  3. Hi! I'm currently working on a WMS MODRAT model of keep coming across some weirdness. Certain actions make my WMS window instantly close and there doesn't seem to be a clear-cut pattern. Sometimes WMS closes when I click to start computing basins, or sometimes even something as small as clicking 'NEXT' on the time of concentration wizard will shut me out. I wonder if anyone else is having these issues as well? Another question I have, unrelated to the crash bug, has to do with having MODRAT calculate my Tc for me. It lists out which basin parameters are missing and in my case, a couple of my basins did not have an 'active time of concentration computation arc' (<- not this exactly, I forget the word for word sentence). Regardless, I go into the basin parameters/attributes to see how I can change this computation arc to "active." I was able to find the toggle for it, but after I click DONE and go back to check, it toggled itself right back to inactive! Does anyone have a clue why this is? I'll come back to edit this post with pictures when I get the model in front of me again. Thanks!
  4. Hi, I'm a student and I'm woking with WMS 11.0, I want to run a stochastic simulation using Manning's coefficients as Stochastic variables, the results of the simulation yields that there is a 100% fllod or 0% wich I think is not accurate, plus there is an error message that seems to pop u during the simulation about WMSRAS.exe. I don't know how to fix the problem. Thanks in advance for your help.
  5. Hi, I've been a heavy WMS user for over 3 years and recently started using the NSS model, and was wanting to know if someone could provide some clarification regarding how WMS is computing the watershed geometric characteristics for input into the regression equations. The regression equations I'm using require an area, a channel slope (at 10/85%), and a main-channel length. I've created a watershed model that is performing satisfactorily, but some of the geometric output numbers are a bit puzzling, specifically the channel length parameter. I've compared WMS output to my own measurements to verify, and sometimes it's a struggle to match any of the WMS numbers at all. I'm referring to both basin-specific channel lengths, obtained by clicking on basin icons, and cumulative lengths, obtained by clicking on outlets. My question is, what exactly is it outputting for that parameter and how is it computing that value? Any information would be very helpful.
  6. I am having a problem with my WMS 10.1.17 where when I run the CleanDam tool and accept changes, but the resultant grid still has depressions. It isn't readily apparent until I run a GSSHA simulation and look at the ponding. When I turn on digital dams in display properties I get no display of digital dams, however when I look at the flow directions with my depth grid, I can plainly see all four arrows pointing inward and a pond. I turn on elevations display values which confirms the flow directions honor the elevation file. I have tried running CleanDam externally from WMS as well with no luck.
  7. Hi all, Why there's a difference in elevations between DEM data from USGS using WMS and google earth? I used DEM data from here: https://dds.cr.usgs.gov/srtm/version2_1/SRTM3/ Is there a better accurate more updated source? Thanks,
  8. Dear All: I have a problem related to use WMS for building the bathymetry of Ce-Qual-W2. I closely followed the tutoiral :http://wmstutorials-10.0.aquaveo.com/35%20WaterQualityModeling-CEQUALW2.pdf. The problem is : 1. For 6.2 Create Branches, I want to only build one branch for my research area. After I created branch coverage, should I also right-click on the “Branch” coverage and select Build Polygon? When I do like this, the wms was crashed (I tested several times). 2. If I didn't build the polygon for my branch, I can continue to build the segment. However, when I finished building the segment and want to do the 8.2 "Branch Identification", the computer crashed again when I select CE-QUAL-W2 | Map Segments ↔ Branches. Could anyone help me find a reason for these two crashes? What I do is closely followed the steps in the tutorial. The bathymetry and the segments are attached below. Note, I deselect the Triangles in the display option. Many thanks and look forward for the reply! Best Cheers Chenxi
  9. Hello, I'm currently using GSSHA to model overland flow processes in a depression-dominated watershed. I've successfully mapped and retained the depressional characteristics of this basin, and have retained these features in the model and subsequent simulations. Now, I'd like to be able to determine the rate at which depressions fill from overland flow, and determine the extent of surface water connectivity between depressions using water depth contours at various times during a simulation. Is this possible using built-in WMS tools? Thanks, David

  12. Hello, I have a model in HEC-Ras version 5.0.3 that I set-up in Civil 3D 2017 (stream alignment, cross sections, LOB, ROB) and I was asked to add in the Manning roughness values from SRH2D. I was asked to do this because I was told that the .geo file from WMS brings in all of the n-values along the cross section, creating a more real-world HEC-Ras model. Currently, I have only 3 n-values. I found a forum that displayed how to correctly transfer the materials file from SRH2D to WMS, and then create essentially the geometry file in WMS to export to HEC-Ras, but I already did most of this in Civil 3D. I don't want to re-do my .geo file in HEC-Ras because it is basically complete. Is there a way to import only the n-values from SRH2D without re-doing my entire HEC-Ras model created from Civil 3D? Thank you
  13. Does anyone know a process for exporting a materials coverage from SMS to WMS? I would like to use a 2-D materials coverage to define Manning's roughness values in a HEC-RAS model I am preparing in WMS 10.1. Thanks!
  14. WMS 10.0 Has been updated! The 32-bit full installation can be downloaded here. The 64-bit full installation can be downloaded here. The Tutorials can be found here. Bug fixes can be found here.
  15. How Can I offset cross sections over a channel at specific distances?
  16. Hello all I am getting confused with the way in which I need to create my bathymetry file in WMS for CE-QUAL-W2 in terms of the initial water surface elevation for my model run. I have been provided a reservoir bathymetry map that was created when the reservoir was at a level of ~509 masl. This is in the form of a raster file from ArcGIS, and I have exported the data as an ASCII file and opened it as a DEM in WMS to be converted to a TIN (as recommended previously on this forum). Therefore the maximum elevation of the TIN in WMS is ~509 masl. But this is not the maximum water surface elevation of the reservoir water level data (just the elevation at the time the DEM reservoir boundary was created), sometimes the water level goes up to ~511 masl. So my first question is how should I address this in WMS when setting up the CE-QUAL-W2 interface? The second question refers to the CE-QUAL-W2 bathymetry input file created in WMS. When I follow the tutorial and set the 'top elevation' when calculating the rating curve, layers etc for the segments. What is the 'top elevation' exactly? Is it the maximum elevation of the TIN, the maximum elevation the water reaches during the model run, or in is my initial water surface elevation on the first day of the model run? I.e. Should I be creating a new bathymetry input file in WMS each time I run the model depending on the initial water level on the day the model run starts? Sorry it's long winded, but I'd be grateful for all guidance anybody can provide!!! Many thanks
  17. Hi folks, I am in the USA and we write our date/time in the format of "Month/Day/Year Hour:Minute:Second AM". I built an HMS model in WMS in the USA. I have imported precipitation time series and linked them to gages. I sent over the WMS files to our partners in Morocco. They open up the precipitation time series and the values are all scrambled up. My best guess is that the date/time stamp is being incorrectly interpreted as "Day/Month/Year". To test the idea, I switched my "Region and Language" setting on my computer to be "dd-MMM-yy". Sure enough, when I open up WMS and open up the files, I get the same scrambled time series. Is there a way to tell WMS to unscramble the time series? Thanks, Lisa
  18. Sorry if this has already been asked somewhere in this forum, but I'm a research student modelling water quality with CE-QUAL-W2, new to both WMS and CE-QUAL-W2, and I'm finding the tutorials/Wiki pages confusing. I would like to create my lake bathymetry in ArcGIS as I have ArcGIS shapefiles and I am applying Kriging, using both land and lake elevation data points, in the interpolation. I then want to just export my masked lake area to WMS to create the segments needed for CE-QUAL-W2. All I've been demonstrated how to do is to import my ArcGIS interpolated data points into WMS as a CSV file with XYZ coordinates and then triangulate in WMS. But to me that seems like I am running two types of interpolation on the same data set?? What is the best way to simply import the prepared DEM, raster file, or TIN into WMS as already prepared ArcGIS data, and simply add the segments, branches etc in WMS without re-editing/interpolating. It is a very simple Lake bathymetry map I need, with inflow/outflow, with no watershed or tributaries etc. Thanks for any help anyone can provide!!!
  19. GSSHA needs observed peak and volume flow data to compare calibration runs for a closeness of fit. If an observed hydrograph has multiple peaks for a single event, how will automatic calibration in GSSHA deal with that? Also, does automatic calibration in GSSHA tends to match observed peak and volume only, but not the shape of hydrograph?
  20. Hi, I am new to the WMS- CE-QUAL W2. I followed the instructions in Using TINs tutorial to import a bathymetry file, convert it to TIN, and then triangulate the TIN. All measurements are in meters. From there, I followed tutorial #9 for CE-QUAL W2 set up. However, during step 9.2 : branch identification, in the select the "Get lengths and orientation of branch segments tool" I get an error message: could not assign length and orientation for segment XX. Also, it seems there are multiple segments with the same number assigned to them (this was not the case right after creating the segments). These segments though have different areas assigned to them. Looking for help on how to proceed on assigning length and orientation. And in case someone has pointers on more detailed tutorials, and other help, it'll be much appreciated. Thanks

  22. What version of GSSHA does WMS 9.1.8 have?
  23. I currently use WMS Version 9.1. I like the "Get Online Maps" and other added features in the new versions. Until recently, I was able to import "World Imagery" and "World Topo Map" but it's been few days when I try to import, error message (attached) pops up saying - "There was a problem loading online image. The Error ID is 20." However, I can still import "NAIP Color Imagery for US".

  25. I was exploring WMS-GSSHA results visualization and I have a question: Is it possible to show aggregated sediment loss on the map for a longterm simulation ? now I can only view one time step at a time , and I was wondering if I can also view sediment lost for example for the whole month ..using color ramp display on the map.
