    Include an option to export/save materials from the "Edit | Materials" window. The user who suggested this to us asked: "Is there a way to save the materials designations (by this I mean the name, color, pattern, and so forth of the soil units or horizons) so that these can easily be imported into a new project. I realize they are saved if I save the project I created them in, but I’d like to be able to just import this information if I create a new project rather than having to rebuild the designations."

    Unfortunately, there is not an automated method to export well transient pumping data for all wells in the format you'd like it to be in. However you can export out the pumping data for each well (if you have them assigned as feature points in the map module) by following the steps below. 1. Double click on a feature point representing a well with transient pumping data 2. Select the button in the "Flow rate" column with the three dots to bring up the XY Series Editor 3. Select the "Export..." button 4. Specify the file name and location and then select "Save" I realize that with many wells this will be a tedious process. I am therefore submitting this as a feature request to the GMS developers. I apologize for the inconvenience.

    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

    Dear Colleagues: This is only a help for the case you get problems when installaing SMS. I have just moved to Windows 7 ultimate, and SMS could not be installed. I got a message "Error 1935.An error occurred during the installation of assembly - HRESULT: 0x80070020". I haved spent some 5 or 6 hours looking for a solution, since I am in a hurry, trying to finish a modelling. Well, after finding several possible solutions and buying a couple of cleaners, the way to fix the problem was very, very simple: - The main problem is the size limit of the registry - The solution: -- Open the registry (regedit) -- Go to HKEY_LOCAL_MACHINE ---------System ---------CurrentControlSet ---------Control ------------ Key: RegistrySizeLimit, type REG_DWORD ------------ Change the size to FFFFFFFF -- Close and reinitiate Cheers, Jose

    If your FEMWATER model was created using a conceptual model, you should be able to double click on the well and change it's attributes using the attribute table. After doing this you will also need to map the changes over to your FEMWATER model

    I don't think you have missed anything. The most simple way to do this with the current tools is with a scatter set and interpolation.

    Remove the "MODFLOW is steady state and one or more of the coverages are transient” warning that appears when trying to save a MODFLOW simulation with transient data in the map module while the MODFLOW simulation is steady state. (requested by a user who says that it gets on their nerves while working with transient models. They said that the warning will always come up since that will always be the case – steady state and transient coverages.)

    Hi Matt, I am not aware of SMS ever being able to export out 3D polyline shapefiles. However, you could export the map data as a dxf/dwg file by right clicking in the "Project Explorer" and selecting "Convert to CAD", then selecting "File | Save As" and changing the "Save as type:" to "AutoCAD Files (*.dwg;*.dxf)". You can then add this AutoCAD file into ArcMap using the "Add Data" tool and the lines will be loaded as Polyline Z features with the elevations specified in SMS.

    I am having a problem when using the "Transform XS2D Panel to Geosection" tool in subsurface analyst. I keep getting an error message saying the following, "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Is there a way to fix this problem?

    Is there a way to vertical hydraulic conductivity values using fixed head differences between two boreholes at the same Horizontal location? For example, if I drill two boreholes just a few feet apart but at different depths there is a good chance that the heads could be different. I want to calibrate my vertical hydraulic conductivity so that there is a few feet head difference between the boreholes. Any suggestions for how to proceed?

    Great! this solves the model checker error message. I made a simplified version of the femwater model and compared it to a modflow one. - brief one layer two bc - constant head (h=2 and h=0 sea level) top and bottom elevation derived from boreholes data (scatter data) refined elemnts I attached the following screen capture show computed head contouring: 4-1 = modflow with 1 layer grid (top and bottom elevation interpolated), plus obs wells, everything seems ok 4-2 = modflow with grid (mean values for top and bottom elevation), plus obs wells, everything seems ok 4-3 = femwater with 1 layer grid (top and bottom elevation interpolated), plus obs wells. The 4-3 model show the total head that is the same as head in modflow. Is it correct? Why the contouring 4-3 is so different? I run the model with different starting heads and the computed heads depends from the initial condition. I coudn't get the obs wells (in conceptual model - obs point) to have the computed head value. I tried to fix their z elevation to match the 3d grid elevation but without success. Thanks dlattuada

    The tin idea gave me a direction to go. After a bit of fiddling. I got the solution I was looking for. I created a tin for the river that only included that area. I created another tin for the rest of the area that used the exact verticies of the river boundary. Then I used a 2d scatter file to create a tin for each layer using the appropriate base tin (river or surrounding) putting them into an appropriately named folder. Using horizons to solids, I used the tin folders and put them to the river or surrounding tin. I then combined the solids that were created into a single folder. That created a perfectly vertical contact.

    I'm glad you were able to resolve the problem. I'm guessing you found the line in the .2dm file Yong Lai has put together for SRH-2D that limits the Manning's Coefficient to the range of 0.0 to 0.2, to help prevent users from using unreasonable values for typical situations. MD 1 "Manning's Coefficient" MV "Manning's Coefficient" 0 0 0.2 The .2dm file is described here. I have attached the SRH-2D template file that we have been using to test SRH-2D and will be distributed with SMS 10.1. Yong Lai has a different version also for SMS 8.1. Both are available from the SRH-2D website. We are very excited about the SRH-2D model. How long have you been using SRH-2D? What types of applications have you used it on? - John srh_2d_model_definition.zip

I'm using WMS and really i did as example SMPDBK in my project but really i need a clear idea about things... Can i see the flooding of dam break in depending of time, EX: After 5 minutes how's the flooding looks like and after 20 minuters how it looks like....and how much of time it takes to reach to some area...?And offcourse the hight of water also in depending on time... Thnx for all... Best regards...

    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

    I tried to run a steady flow through my model in HEC RAS. I get the error 'Station and elevation data contains duplicate points - The cross section filter can be used to remove duplicate points' These extra points can be deleted manually, but it takes awhile and I can't seem to find this "Points Filter" function in HEC RAS. If anyone knows please give me heads up. Thanks

    Hi Ashish, That is very interesting that your water surface rises when lowering the Manning's n value. Maybe something else in your model is changing, causing your water surface to rise. I'd compare everything in your models before and after changing the Manning's value. Has anybody else seen this or have any input on this topic? Chris

    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

    Hi all, I am trying to figure out how to treat four irrigation ditches over the mainstem of a HEC-RAS in WMS model. Each one diverts and returns to either the mainstem or a tributary right before the tributary joins the mainstem. Any input on how to place diverted flow? Add a outlet point? Thanks for any thoughts or ideas, Rob

    Hello dear community, Searching for a solution to my problem, someone recommended me Aquaveo. I will shortly describe the issue and hopefully ,in time, I can reach my goals with your help. The topic would be a simulation (using GIS techniques) of the area that will be affected by floods if a dam breaks, I guess we can call the objective a flood zone risk map(the scenario refers to a hypothetical dam rupture because of some reason and the flood induced by the water (lake) that is retained by the dam). I want to make this study on an accumulation lake near my home city. Floods are a major problem in my country and this study could help in risk assessment projects. I find difficulties in: 1st of all, in choosing the software(extensions) that could do this. 2nd - establishing the data needed in order to get the maximum out of these programs 3rd (possibly a 2nd)the methodology that needs to be followed. I read a few recommendations made by Mr Chris Smemoe about using HEC-RAS and consulting the users manual. I think this could be a 1st step but the issues mentioned before still remain unclear. Please do not think that I want others to do my job, I just want someone to show me guidance in this matter because our teachers are not very experienced in these sort or studies. Please let me know if I should mention properties of the dam construction or/and volume data of the water that it retains (properties of the lake that would flood the zone if the dam breaks). Kind regards to the WMS community,

    When exporting from a Time Series plot (Display | Plot Wizard | Time Series | right click on plot | export/print) , make the time accurate to more than one decimal place, as the Active Data Set Time series does (4 decimal places). The "Maximum Precision" option does not seem to change the output. (requested by user)

    So one of my first projects with WMS/HEC-RAS involves an entire river system, with multiple lakes and dams along the entire system. I understand how to bring cross-sections and dams from WMS to HEC-RAS. However, how do I model the lakes that the dams actually hold back? My basic understanding of these two programs shows that on HEC-RAS I can model Storage areas, and I can connect the Areas to a certain cross-section. Can I place a connection for a storage area (aka my lake) on the cross-section that drains into the lake, and then another connection on the cross-section that models my dam? Also, if I model a storage area on HEC-RAS, what will read back into WMS? Will it work?

    Installed also 8.1.3 and used an existing and working model. Did map to modflow and a CHD boundary condition was gone. The arc of the boundary condition was exactly on the boundary of the cells. Moved the arc a little inside and the CHD boundary appeared again after map to modflow. Will install the new update of 8.0

    KMerriman, I ran into this issue a couple weeks ago. I was trying to map velocity in ArcMap. I found that some of the polygons were missing. I found that it is just an issue with how the data set contours (velocity mag. for example) were defined in SMS and ArcMap. So, how you define the contour intervals for the data set in SMS affects how it immediately appears in ArcMap. But you can change the interval settings for the layer in ArcMap to get everything to show. Go to your data layer in ArcMap Right Click -> Properties -> Symbology -> Quantities -> Graduated Colors Select the appropriate Value under Fields box (example ELEV_AVG) Under the Classification dialogue box adjust the number of classes (depends on the range of contour values). Click classify to define the interval of the classes. You will have to play around with this to get it to map how you want. Generally, if polygons are missing you need to refine the classes so the values of the missing polygon are represented. Hope that helps.

    Other users have reported this problem in GMS when they had CAD data loaded and tried to save. If you do have CAD data, could you try converting it to feature objects, deleting it and then saving the project again? If you do not have CAD data, would you please upload your files to our FTP site by following the instructions below so we can look into the problem? 1. Create a new folder with a unique name on your computer and copy all of your project files into it. (please zip up the folder) 2. Open windows explorer (My Computer). 3. Enter "ftp://pubftp.aquaveo.com/incoming/" in the address bar. 4. (If the "Log On As" dialog box appears) check the box labeled "Log on anonymously" and click "Log On". 5. Copy the folder with your project files in it into the "incoming" folder. 6. Send an e-mail to support@aquaveo.com telling us the name of the folder you uploaded and exact steps taken to produce the problem. *Please help us stay organized by putting all of your files in a single folder before you upload them. After you upload the files, you will not be able to edit them.

    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.

    I am curious how GMS calculates the magnitude of flux in the CCF files. From my understanding, the magnitude of flux of a grid should be the summation of the flux from the 6 faces bounding the grid. However, it seems the value from the CCF-Mag file does not match this value. Anybody has an idea why this happens? Here is an example: i ,j ,K ,Front ,Right ,Bottom ,CCF_Mag 1 ,1 ,1 ,0 ,4.83 ,0 ,4.83 1 ,2 ,1 ,-1.10E-03 ,6.59 ,-1.82 ,12 1 ,3 ,1 ,-7.65E-03 ,6.61 ,-6.86E-02 ,13 Take the grid (1,2,1) for example, the flow from back and upper faces are 0, because this is the first row, and first layer, and no recharge or precipitation. Then the flux calculation is the summation of front, right, bottom and left faces, which is Flux = -0.0011+6.59-1.82-4.83 =- 0.061. But the value from CCF_Mag file is 12.

    I have a centerline coverage and a cross section coverage along with a TIN. I'm trying to define roughness values for the model. I have created materials in Edit | Material Data and entered roughness values in HEC-RAS | Material Properties.... when I go into HEC-RAS | Model Control there is no option to select 'Materials' for use in generating roughness values. Do I need to build polygons and creat a new coverage for the roughness values? roughness.doc

    Hi all, I am working towards a working HEC-RAS model from WMS input. I have a centerline, channel banks, and cross sections to define model geometry in HEC-RAS. I have saved as a 1-D network schematic, but when bringing it into HEC-RAS, it will only use one of these coverages to define geometry, so I get error messages saying that there are no cross sections. Any thoughts (Chris and Clark, I'm looking at you)? Thanks, Rob

    I set up a model and entered the unsteady flow data into HEC RAS 4.0 Beta. When I click compute the geometry processor runs smooth with no errors and then the analysis stops without initiating the unsteady flow simulation. There is no indication or output with errors explaining the problem as to why. What is wrong with my model?

    It would be great if the elevation attribute of a contour would also be mapped to the contours while using the MapInfo File Interchange format (.mif) for exporting, similar to exporting to arc shape files. Right now all contours have no elevation at all. In contrast to arc shape files created by GMS, Manifold can read the .mif files created by GMS so this would probably be a workaround for that problem also.
