    Hi, My University has a parallel computing system and I would like to know if there is a parallel version of ADCIRC model to run the SMS in that cluster, using e.g. 20 processors. If yes, can you give me information about how it works? Thanks, Amy

    Is there any way I can open a Mike21 FM mesh in SMS in order to create a dxf file? I have converted the text version to a 2dm format. When I try to open it I get a message that I don't have enough memory even though Task Manager indicates that there is memory remaining. Is this message generated in SMS or Windows? We are using a Windows XP 32bit system with 3G memory. We will eventually upgrade to a 64bit system and that will probably solve this problem but in the meantime??

    I assume that you want to model Seawater intrusion into groundwater. The most popular model for doing that is SEAWAT. GMS version 8 will have an interface to SEAWAT. GMS currently has an interface to FEMWATER (finite element model) that can also handle salt water intrusion problems.

    It sounds like the DEM is really big and you need more memory to handle it. If you have a 64 bit machine, download the 64 bit version of SMS. If you don't, then you may have to filter points out to make it something your machine can handle. Cameron

    I was able to run the MODFLOW SFR2 tutorial model. I would recommend going through the MODFLOW-SFR2Package.pdf tutorial located in C:\Program Files\GMS 7.0\tutfiles\MODFLOW. There it explains how to set up a model using the SFR2 package. You can also see a finished model that uses the SFR2 package in C:\Program Files\GMS 7.0\tutfiles\MODFLOW\trans\sample. If you need to download the tutorials, you can find them here.

    Well, loading the map file put most of the important stuff back up, and worked just fine. I had to retrieve a new TIN, and extract my cross sections again, but other than that, it seems ok. I am working on schlepping the 37 MB zip file of the model that wasn't opening to tech, just to see what was causing it to freeze. Thanks, Rob

    Rob, I'm not sure that you need to even model your diversions if you are having problems modeling them. You could just do a cross section before and after your diversion and place a flow change location at these cross sections in your HEC-RAS model. You might be able to do what you mention above in HEC-RAS, but I don't know how WMS would handle it if you have multiple downstream terminus points in your HEC-RAS model. Chris

    Hi there I am desperately trying to insert a new part of a mesh into an existing mesh. First I tried to insert the new nodes into the existing mesh and then trying to cut out the old elements of the existing mesh with the boundaries from the new mesh (there should be now a "hole" where I can append the new mesh) But the system is either running out of memory ??!! or is crashing. The existing mesh contains about 56000 points and the new part about 6000 points. I think this isn't too big for SMS or my system. I am working with SMS V10 including the newest patch. Any suggestions or hints? Thanks greetz Chris

    In testing the new capability to export film loop to kmz, I have found a slight positioning error when viewing the animation in Google Earth. The horizontal shift looks to be about 15 m. For background, I am importing TUFLOW results into SMS 10.1 and then setting the projection to the appropriate global projection (Map Grid of Australia Zone 56) and datum (GDA94). Although the error is small, its enough to make the results look incorrect when viewed closely (eg. roads/houses are inundated when they are actually dry). When the raw TUFLOW results are mapped in our GIS (ie. independent of SMS) there is no spatial error. Similarly, when I import the background aerial (ecw file) into SMS the results overlay correctly. Has anyone else found similar issues exporting to GE? And hopefully resolved them! My guess is that the problem is going back to lats/longs in GE, and therefore not something that can be worked around. Cheers, Nick

    Let me see if I understand You have a .geo file with linear or quadratic elements You have a .sol file with a value for each node in the .geo file When you read in the .sol file after reading in the .geo file you get an error message saying, "THE SOLUTION FILE DOES NOT MATCH THE MESH" I believe we will need to take a look at your files. Please send them to technical support.

    Hi, I am using TUFLOW in SMS 10.1 and I would like to link a fine Grid in some areas to a coarser Grid. We already ordered the multiple domains license. When I try to link the two 2D domains according to the help file on http://www.xmswiki.com/xms/SMS:TUFLOW_Linking_2D_Domains as below To setup multiple 2D domains in SMS: 1. Create multiple TUFLOW grids and associated grid components. 2. Define a 2D/2D Linkage coverage and attributes (see below). 3. Add all the 2D domains being used and the 2D/2D Links Coverage to the simulation. the program always tells me, that "this component already has a grid linked to it!". So what can I do to get this thing done? I already posted my question in the TUFLOW forum and they gave me a Tutorial. Unfortunately the multiple domains tutorial is not yet documented and so it is not easy to understand, how to use this tool. Kind regards

    So I'm using the Grid Overlay with Keq method and have 4 materials in my solid. Each one has a different Kh and a Kv set at 1/10 of the Kh. Based on my understanding of the method and the help description ("Rather than simply assigning materials based on which solid encompasses the cell centers, the Keq method attempts to compute a custom Kh and Kv value for each cell. When assigning the material properties to a cell, GMS computes the volume of each solid in the cell and computes an equivalent Kh, Kv, and storage coefficient for the cell that takes each of the solids in the cell into account. Thus, the effect of a thin seam in a cell would be included in the Kh and Kv values for the cell."), I would expect to see my resulting Kv for each cell be 1/10 of the Kh computed. I am finding that the calculated value is often much lower than the expected value. Does anyone have insight on this matter?

    Correct me if I am wrong, but I understand that van Genuchten characteristic curves, while realistic and commonly used, present difficulties in practice. They are highly non-linear, which means that a fine spatial scale is required to achieve convergance and/or good solutions. Vogel & Ippisch (2008) Estimation of a critical spatial discretization limit for solving Richard's Equation at Large Scales. Vadose Zone Journal 7(1) 112-114. So how do people handle this?

    I would like to ask something. I am trying to do the exact same thing with Chris24. I have a small mesh with 12000 elements and I try to append this small mesh into a larger (1million elements, 500000 nodes) mesh. I got the necessary hole in the big mesh and removed all the clashing nodes. Following the below procedure, my machine crashes when meshing (after 8th step) This is using SMS 10.0.11 When I am using the same meshes in SMS 10.1, it crashes at step 3 when trying to create the polygons. To automatically fill the transition zone: 1. Create a new coverage that is empty and set to the model type you are using. 2. In the 2D Mesh module, select the menu command "Data | Mesh -> Map" 3. Select "Mesh Boundaries -> Polygons" 4. At this point you may want to delete all arcs except for the arcs defining the transition area polygon. 5. Switch to the map module and select "Feature Objects | Build polygons" 6. Double click on the transition area polygon and set the meshing parameters - you will probably want to use paving for the mesh generation. 7. Once meshing parameters are set, select the menu "Feature Objects | Map -> 2D Mesh" 8. In the 2D Mesh Options dialog, uncheck "Delete existing mesh" My desktop pc specs: DELL Precision T3400 Intel Core 2 Extreme CPU Q6850 @3.00GHz 8GB of RAM Microsoft XP Professional x64 Edition Any suggestions? Thanks Onur

    I believe ADCIRC may be more stable when wetting and drying is occurring. However, if you want to use your hydrodynamic solution to run RMA4, you will need an RMA2 solution. It sounds like you have most of the data you would need to use the reflection / absorption BC - can you also get TAREA? You may also want to consider extending the mesh if possible so you don't need to use a reflection / absorption BC. It is more difficult to get a solution from models with wetting / drying - I also believe the reflection / absorption BC can be difficult, and it is hard to know what value to use for BETA.

    The quick answer is "not directly." Check out this link - http://www.xmswiki.com/xms/GMS:Importing_MODFLOW_Files In the past, I took the VM files and edited them to have the proper format for importing (I didn't have a VM license at the time to be able to export generic MODFLOW files). It took a little time, but it worked.

    Mark, Tom just tried doing the conversion in SMS 10.1 and the results look correct. We did a major overhaul on our coordinate system support in SMS 10.1. You may want to try downloading SMS 10.1 Beta from the Aquaveo Downloads page and using it for this project. - John

    Transient data needs to be in a "step-type" format (duplicate data points to end one stress period and start the next). This could be one problem. Not having imported transient data for a while, I don't recall if it will do some of this automatically when you import data. The last error is not necessarily a big deal, depending on how things turn out. You may be running your model for a certain length of time or for stress periods that don't match up exactly with your transient data and the model just says it doesn't line up (but it will attempt to line things up).

    Matevz, You may want to check your units. They should be consistent each time your are entering parameters for the model. The "Edit | Units" dialog should be set up correctly, and these units should be used in each subsequent step. In the "Seep2D | Analysis Options" dialog, is the "Compute flow lines" check box activated? If not, it should be in order for them to appear. Regards, Todd XMS Technical Support

    Hi John Thanks again for your reply. Thats exactly how I tried it today, but the programm is crashing while linking the two meshes with paving. Well, I think I have to "fill" up the gap between the two meshes manually. greetz Chris

    Hi all I have been trying to run a simple PTM run to test it's capabilities. First I tried forcing the particles with outputs from a CMS-FLOW simulation I completed recently. While I followed the documentation as closely as I could, and was confident that I had set everything up correctly, the model would not run, and kept giving the following error message: forrtl: severe (157): Program Exception - access violation I thought that perhaps the problem was with using the CMS-FLOW outputs, so I tried to force the particles with outputs from the ADCIRC tutorial simulation. Again, after setting up the model I received the same error. I have tried a number of variations on the model setup: different time steps, with and without particle sources/traps, etc. I also downloaded and installed the latest model exe updates, without success. If someone could provide any insight on whether I'm doing something wrong, or whether there is a bug in the model it would be much appreciated. Regards Joel

    I am using HEC-HMS to model snowmelt, and have several questions: 1. What are reasonable values for the ATI (antecedant temperature index) meltrate function? Similarly for ATI meltrate coefficient? Alternatively, what are some reasonable methods to determine these values? It isn't clear to me what these really are. 2. When I run the model, I get an error message that melt rate is undefined for my first time step (even though I have numbers for ATI function and coefficient. Any insight as to why I am getting this error message and how I can correct it? Thanks, TFree

    There is still time to register for the training course "Hydrologic and Hydraulic Modeling with WMS" March 10-13, 2009 in Orlando, Florida. For more information, see http://www.aquaveo.com/wms_training_orlando. In this hands-on, application oriented training course you will learn how to use automated hydrology and hydraulic tools in the Watershed Modeling System (WMS). Upon completion of the course, you will know how to obtain and use GIS data and digital terrain data in watershed modeling, floodplain analysis and mapping. You will also learn the software tools needed to process this data, create numerical models, and generate digital watershed and flood maps. This course will provide practical training on the use of software tools to aid in the hydrologic and hydraulic analysis and floodplain delineation. The use of the Watershed Modeling System (WMS) for watershed runoff analysis, coupled with channel hydraulics, will be the focus of the course. An integrated, GIS-based approach to hydrology, hydraulics, and mapping will be presented step-by-step, with computer worksessions, to allow participates to implement the concepts presented. Participants will gain experience in using the software to create 1) GIS-based hydrologic simulations using NFF, HEC-1 (HEC-HMS), TR-55, TR-20, or Rational Method 2) hydraulic simulations (HEC-RAS) from the hydrologic model results and GIS data. The final step will be using WMS to interpret hydraulic model results in conjunction with digital elevation data to create flood extents maps, flood inundation maps, flood depth maps, and flood impact maps. Automated watershed delineation will be covered in detail along with application of GIS data layers to compute common hydrologic and hydraulic modeling parameters (Curve Number, Manning's roughness, Green & Ampt parameters, travel time, etc.) Since this course will focus more on application than on theory, a knowledge of basic rainfall/runoff modeling principles is recommended, but not required. The training course is taught by the WMS developers and will use the latest version of WMS. The 4-day course will familiarize attendees with the following topics: * Watershed delineation from digital elevation data (USGS DEMs, survey data, etc.) * Use of digital terrain data for basin lag time and time of concentration computations * Data exchange with GIS systems for hydrologic model development including: - Use of vector (basin and stream) coverages for creating model input files - Land use and soil type coverages for composite curve number generation * Incorporating man-made/urban interference in watershed modeling * Set up and use of the following hydrologic models: - HEC-1 - TR-20 - TR-55 - Rational Method - National Flood Frequency Program (USGS Regression Equations) * Generate HEC-RAS models from GIS and terrain data. * Find out how to link hydrologic and hydraulic models to perform uncertainty analysis in floodplain modeling. * Learn to create approximate (Zone A) and detailed (Zone AE,AH) FEMA flood maps * Creation of professional output in the form of images, plots, and video clips * Preview of additional WMS Modules: StormDrain, GSSHA 2D modeling

    Open the Geometric Data editor and look in the Tools menu. You should see a tool called "Cross Section Point Filter." It's not as easy as saying "Delete all my duplicate points" but you can set criteria such as slope, vertical, and horizontal tolerances that HEC-RAS will use for filtering. If you want to minimize the number of points that get filtered, just set the tolerances really low and that should get rid of the duplicate points and maybe a few others. Clark

    There is no tool in GMS to do exactly what you want, but here's a possible workaround. There is an interpolation option to "Assign default extrapolation value to hidden objects". You can use that in combination with hidden mesh elements and the data calculator to create the type of data set you want. What you would do is hide the elements pertaining to the upper aquifer, then interpolate from scatter points to the mesh using the option mentioned above and a default extrapolation value of something like -999 or some number much less than you have in your data. Then you repeat the process but this time hide the lower aquifer elements and interpolate to the upper aquifer. Then you use the data calculator and create a new data set that is the max of the two data sets you just created which will get rid of the -999 values. You can then export that data set and use it for your initial condition.

    Does any one have any tips on how I can increase the memory available to WMS. I'm working with large elevation dataset and while doing things such as building tins, reading in text files (high resolution aerial survey xyz files), delineating floods, etc. I am routinely getting an "Out of Memory" error that forces me to stop what I'm doing, close WMS and open it back up. Usually I can not even save my progress because I get the out of memory error when I try to save as well. My desktop configuration is as follows: Core 2 Duo 2.66GHz E6750 CPU 3.00 GB RAM 32-bit Windows XP Professional SP2 I'm not multitasking while using WMS, and it seems like it can read 2 or 3 (50 MB) elevation data sets before it runs out of memory. Is there a cache I can increase or periodically empty? increase the windows page file size? Any, suggestions would be much appreciated. -Clint

    Right now MODPATH is computed based on the active MODFLOW solution. If I have an mt3d solution loaded as well and activate it then I get an error that MODPATH could not run. It would be nice to be able to specify the MODFLOW solution that will be used with MODPATH in addition to using the active solution.

    Hi. I'm just wondering if someone could enlighten me as to how CGWAVE or SMS dissipates wave energy following breaking when a ratio of H/h is used (wave height/water depth) rather than using the wave breaking option in the actual model. Thanks, Brett

    Hi GOAL: Determine wave height and period in a harbor during a storm METHOD: set up two grids; one is for offshore growth; second is for the harbor itself, where higher accuracy is needed. Grid 1 is 'wind' only for wave generation, the second grid is set up to spectra (from the parent grid) and wind. APPLICATION: I use the 'nested grid' technique successfully HOWEVER: At this point I cannot say for sure that the child grid is actually using the wind spectrum, so there is no wind-wave generation! Can you help with this? My setup is: 64-bit, 10.1.11 (25-jan-11) on XP. Thank you. John

    Hey folks, I am working on a RMA 2 steady state model and received the following message in the output: --> ZERO OR NEGATIVE AREA for Element= 4544 Imat= 0 ignor if imat > 900 This message is repeated about 200 times for the various elements. This doesn't appear to be a catastrophic error as I still get reasonable results from the model. I understand that this is a result of elements connection being made clockwise rather than counter-clockwise. I haven't been able to determine from the user manual/tutorials how to re-connect the elements in the appropriate direction. If anyone knows of a tutorial that describes this process I'd appreciate hearing back from you. Cheers.

    Hi, I am pleased to announce that the beta version of SMS 11.0 has been posted on the website. SMS 11.0 contains a few new interfaces and lots of new or improved features both specific to individual models as well as general features everyone can benefit from. To enable SMS 11.0 beta, request an evaluation license. When this expires, please contact sales@aquaveo.com to get a longer beta evaluation. You can download the beta installation from: www.aquaveo.com/downloads/sms *Note: Currently the installation does not include a new TUFLOW or ADCIRC executable. In order to try SMS 11.0 with these models you will need to use the versions compatible with SMS 10.1 and you will need a 10.1 license for the model on the computer. The new TUFLOW Advection/Diffusion module for TUFLOW is not available yet. We hope to get these updated and included into the beta install soon. The new features are listed below New Module - Raster Module You can now work with raster data (DEM) in SMS without needing to convert the data into a scatterset (TIN). Raster formats are more space efficient and quicker to draw than TIN based formats with the same number of points. This allows you to work with larger DEMs than previously possible within SMS. Rasters can be used to interpolate elevations to a scatter, mesh, or grid. You can create observation profile plots of raster data to see cross-section views of raster data. New interface - ADH The 2D shallow water component of the ADaptive Hydraulics Modeling system (ADH) now has an interface within SMS. ADH was developed by the Coastal and Hydraulics Laboratory, ERDC, USACE (www.chl.erdc.usace.army.mil). ADH solves the 2D shallow water equations, features an adaptive mesh solution to dynamically alter the resolution of the mesh based upon where it is needed, supports wetting and drying, boat effects, and wind effects. See the ADH website for more information on ADH (https://adh.usace.army.mil/). Note: The sediment and AD transport portions of ADH are not currently supported in the SMS interface. New interface - WAM The global ocean WAve prediction Model called WAM is a third generation wave model. WAM predicts directional spectra as well as wave properties such as significant wave height, mean wave direction and frequency, swell wave height and mean direction, and wind stress fields corrected by including the wave induced stress and the drag coeffieient at each grid point at chosen output times. (http://chl.erdc.usace.army.mil/chl.aspx?p=s&a=software;8) The WAM interface in SMS supports building WAM grids, creating WAM simulations, nesting WAM grids, post-processing support (contours and spectra), and generating spectra for STWAVE input (requires the STWAVE interface). New tool for Runup/overtopping using Bouss2D It is now possible to run Bouss2D in 1D mode to simulate run-up and overtopping. The runup/overtopping interface supports the ability to extract transects, position gages, specify roughness zones (Chezy or Manning), and define multiple wave cases. Post-processing includes 2D profile plots along transects, time-series plots of gage output, generated summary statistics such as height of highest 1/10, 1/50 of waves, and the point of furthest encroachment on each transect. New functionality to TUFLOW interface - Advection/Diffusion Module There is a new Advection/Diffusion (AD) module for TUFLOW. TUFLOW AD simulates depth-averaged, two and one-dimensional constituent fate and transport. Both dissolved and particulate constituents can be simulated. TUFLOW AD adaptively expands its computational stencil (between third to ninth order) in areas where strong constituent gradients are identified. The module is fully supported within SMS including the ability to support spatially varied initial concentrations and transport coefficients. New or Improved Generic Model Features We have added several features to the generic model interface to offer more options for providing a user-interface for models without a custom SMS interface. Now boundary condition and material parameters can now support more than just a floating point or curve value. Each parameter can be enumerated options, boolean, integer, float, curve, text, or float/curve (user chooses which). Now multiple boundary conditions can be assigned to the same entity (node, nodestring or elements). This is particularly handy if you have bc information for multiple solution types (flow and sediment transport). The generic model designer can show/hide parameters based upon an enumerated option parameter. For example, the user could choose between chezy and manning roughness approaches and show the appropriate parameters depending upon the choice. Boundary condition and Material properties can use global parameters or their own parameters to base the hide/show logic. The designer can also choose to have multiple material groups (roughness/sediment). In order to accomplish the features above and make parameters as consistent as possible, some existing card definitions have changed. This will necessity changes for models using the generic model interface and migrating from SMS 10.1 to SMS 11.0. *Note - In order to take advantage of the above options, the model developer has to make some changes. If you are a template user, you will need to wait until an updated template is available. CMS Updates CMS Flow now supports the ability to run a coupled CMS Flow/CMS Wave model without the use of the steering module (inlined). Running the models inlined minimizes the file IO for the models decreasing runtimes. CMS Flow also supports an optional Implicit solution scheme allows for longer time-step sizes and parallel runs so you can distribute your work across all of your processor cores. The option to change which mode (2D or 3D) CMS Flow runs in has been removed. By default, CMS Flow will run in 2D. CMS Wave has several new features including the ability to define a muddy bed, non-linear wave effects, infragravity wave effects, spatially varied wind field, xmdf output, and a Gauss-seidel solution scheme that allows you to run across multiple processor cores. TUFLOW Updates You can now import projects created outside of SMS. Multiple TCF files can be read together to maintain sharing of objects where supported by SMS. Makes it easy for someone familiar with SMS to pick up on a model started by someone else or to help transition to using TUFLOW within SMS. You can now choose to output datasets in XMDF format which is much faster (basically instant) for loading datasets into SMS. You can also add custom text to the output options to choose items not supported by SMS. You can now create, manage, and use irregular culverts from inside the SMS interface. You can now choose to have SMS write zpts to a new xf file format that is binary and very fast to read/write. Includes manhole support for the new TUFLOW manhole features. You can specify options for the automatically generated manholes and override these settings using a TUFLOW manhole coverage. You can now select grid cell locations (9 cell locations used by TUFLOW) using the “Feature objects->Select/Delete Data” command. Cartesian grids store their own projection and reproject on the fly You can now have a projection associated with each of your cartesian grids. The grid will be reprojected on the fly into the working projection for display purposes. You can right-click on the grid and choose “Work in grid projection” to easily change your working projection to the grid’s projection which is required for working with the grid and using tools. Note: Bouss2D and CMS-Wave do not currently have the ability to save this projection information. STWAVE Updates We are now linked to STWAVE version 6 which has new file formats and improvements made by the model developers. You can now extract boundary conditions from a larger WAM run and have improved iteration control for the full-plane version. The new interface/model allows you to specify names for your boundary condition cases. Improved Crash Reports The crash reports from SMS now contain more information often enough for our developers to fix the issue without any user interaction. Please allow SMS to post this information so our developers can fix issues that arise. Dynamic background images from the web through ArcGIS If you have ArcGIS on your computer, you can use the GIS module within SMS to get background imagery that updates on the fly from the internet. Particle module/PTM changes Particle sets can have a projection defined and are reprojected on the fly. You can estimate the number of particles that will be generated in by a PTM source coverage. This helps ensure you don’t accidentally generate so many particles that the computations take to long. Virtual gages - You can use virtual gages to determine concentrations and other data around a point or within a polygon. Particle filters - You can use particle filters to display a subset of particles to use for display, selection and compute grid datasets. You can use this to look at particles from particular sources, etc. Bouss2D changes You can now have variable roughness defined by map polygons for a Bouss2D simulation General Features If you do file | Save as and choose an image file, SMS writes an associated world and projection file You can change the symbol size used in plots You can convert mesh elements to polygons using Mesh->Map. This makes it possible to get your mesh elements into a shapefile SMS now uses the existing background for flowtrace and drogue plots rather than have this specified separately “Zoom to” options to easily see specific information including: zoom to mesh, grid, scatter, and selections Option to always use white when printing rather than current background color You can now import TINs from LandXML files Find/select map points, arcs, and polygons by id (use zoom to selection to find in busy coverages)

    Hello everybody, I was trying to figure out how the gradient of a given scatter set is calculated in the data calculator - spatial option. In the wiki I found this definition: "Gradient. Creates a function that gives the gradient at each node. The gradient is calculated as the run divided by the rise." Is it possible to have a more explicit definition? in particular, as I suppose the run is the distance between two nodes and the rise the relative vertical difference, the gradient at each node is then the average of run divided by rise between all its neighbor points? how many points are considered? Thank you Andrea

    I am exporting a surface to a LandXML file so I can import the surface in SMS 11.0. It appears the the northings and eastings are reversed. The landxml points are listed as a (northing, easting, elevation) pr (y,x,z). The way the surface is displayed in SMS looks to be (Easting, Northing, elevation) or (x,y,z). Has anyone else experienced this problem? Or is there a way to change the way the coordinates are read? I am using Pennsylvania State Plane Coordinates. Thanks for your help.
