  2. Time-axis label format setting

    Hisham, we have had others report the same behavior to Aquaveo technical support in the past. We submitted the issue for feedback from our AHGW development team. They discovered that it was not a bug in the AHGW processes but rather in the ESRI plotting tools since AHGW uses the ESRI plotting tools in this process. The customers that have reported this in the past were all using ArcGIS 10.3. Are you by chance using ArcGIS 10.3 or earlier? Up until now we have not had any reports of this occurring with later versions of ArcGIS, so it is possible they have fixed the plotting issues. -Cody
  3. GSSHA long-term simulation

    Vaclav David, Just looking at your screen, there are 2 things I can think of that might possibly be incorrect in your model. One possibility is that you are trying to run a storm drain model without having defined channel routing in your model. There was a bug in GSSHA that was recently fixed where if you tried to run storm/tile drains without channel routing defined GSSHA crashed. This has been fixed if you download the latest gssha.exe from http://gsshawiki.com. Another possibility is that your GSSHA output window states that there was an error encountered in the hmet_WES file. This is your HMET file used in your long term simulation. You should probably attempt to fix this error and see if this fixes the problem. I believe sample files are located on gsshawiki.com and there are some sample files in the long-term modeling example from the WMS tutorials. You could also contact our Tech support department with your files if you have a current maintenance contract for WMS. Let me know if I can be of further assistance. Chris

  5. GSSHA long-term simulation

    Hello everybody, I'm trying to run long-term simulation but it falls down very quickly. I suppose that the problem can be in my precipitation data file (.gag) as the last message concerns the precipitation data. Is there anyone who could confirm that to me? I attach the printscreen. The .gag file can be found at /data/files/osobni%20stranky/Vaclav%20David/model_data20180222_6_cont_prec.gag THanx in advance for any advice. Vaclav David
  6. Diverting a Drainage Path

    Mike, I just saw this and you have some strange things happening. If you still have the files and get a chance, it would be nice if you could contact support@aquaveo.com or call them with your files so we can see what's wrong with importing your flow directions. Thanks, Chris
  7. Routing Data

    Joe, Thank you for your input. I think this is a good suggestion and would not be difficult to do. I added it to our task list. In the mean time, there is a "filter" tab that's available when you are in the cross section attributes dialog. This tool allows you to reduce the number of points in your cross section to a certain number of points based on certain criteria. Chris
  8. Importing Survey Data

    Joe, You should be able to get survey data into WMS. Here's what I do to get it into WMS: 1. Select FIle | Open and select the .csv file. Here's my sample .csv file: 1, 1, 2 2, 2, 3 1, 2, 4 2, 3, 5 2. In the dialog that pops up, use the defaults and select "Next" 3. Under "WMS Data Type", select "Survey Data", then Finish. 4. This brings your data into WMS as TIN vertices. If you have vertices turned off, you won't see anything. To triangulate your vertices and show contours, select TIN | Triangles | Triangulate from the Terrain Data Module menus. You will see the triangles and contours. Let me know if you need anything else, Chris
  9. Index is out of range

    Dear GMS users, I am experiencing the same issue when mapping my recharge coverage to MODFLOW, while I could map the recharge correctly without errors so far. The error remains even if I switch back to steady state. Anyone knows how to solve this problem? Thanks in advance
  10. Hey all! I have a question regarding boundary condition set up. I am working on a regional model of an large aquifer field which is used for drinking water purposes. Hydrologic and hydrogeologic conditions are at this stage of the research verry clear. We are dealing with open aquifer field where boundary condition is representing inflow to the aquifer from surrounding sedimentary formations. We have calculated the infow using National groundwater recharge model and at this stage we have data of infow (Q [m^3/s]) for every cell of the boundary condition. Is it possible to calculate the needed hydraulic head in order to simulate the boundary conditions as constant head?
  11. I'm trying to bring in field survey data into WMS, but am having trouble getting it to appear correctly. The *.csv has northings, eastings, z's and I can group them generally in the section groups. Do I need to determine "D" outside of WMS?
  12. MT3DMS Error with MODFLOW-NWT

    Hi all, I am attempting to run a MT3DMS simulation (and eventually SEAWAT, too) with MODFLOW-NWT, and MT3DMS reports this error: Error Reading Flow-Transport Link File Possibly Caused by: 1. Incompatible Styles of Unformatted Files Used by MODFLOW and MT3DMS; 2. Unformatted Flow-Transport Link File Saved by Verison 1 of LinkMT3D Package Which Is No Longer Supported by MT3DMS. Has anyone come across this before and has a suggestion on how to fix? It may be related to a GMS bug (I am using version 10.3.5, 64-bit) as I have tried an older model that successfully ran MT3DMS last year on an earlier version of GMS, but that model now reports the same error. I have contacted GMS support, but they are very busy and slow to respond, so I thought I’d ask the user forum to see if anyone had a solution. Thanks.
  13. Hi all Playing with the time series tutorial, I am unable to get the time-axis labels to plot correctly. I get years like 1899, 1900, 1901, etc. The time series table is fine though. Any ideas/suggestions? Thanks

  15. Coverages on the same plane

    Cool, thank you for your help Cody!
  16. Coverages on the same plane

    mikeg20, the Z location of the features in the SRH-2D Boundary conditions type coverage displayed in your two images is not important. That is the case for most map coverages with a few exceptions. Since it appears you are using SRH-2D the one SRH coverage type which does make an exception is the SRH-2D Obstructions coverage which uses the z location of arcs and points to define it's position in the z direction. -Cody
  17. Coverages on the same plane

    New SMS user here... just wondering, does it matter if all the coverages are on the same plane? I have noticed that when you switch to the 3D mode, depending on what coverages are visible when you create them, they appear in different planes. I am just wondering if this is what is causing my model to crash. I have run a successful model, but I never actually noticed this scenario. Now, this model won't run, and I am curious as to if this is the reason? Any advise or knowledge pertaining to this situation would be great! I have attached 2 separate pictures showing both scenarios encase my explanation was poor. Thanks!
  18. Transient spatially distributed recharge

    Thank you for sharing the solution. Nice one Have you used some sort of interpolation to obtain modflow compatible dataset from the raster data? Or is the grid and rasters identical in number of rows and columns?
  19. Hi, try preparing the transient dataset so, that for each polygon in GMS coverage, there is a corresponding timeserie with the polygon id assigned at each row of the dataset. It will be a large dataset, but GMS should handle it unless you run out of memory.
  20. Dear Hisham & Michal, the procedure you mention, I think, refers only to steady-state models and we have already applied it in this type of simulation with no problem at all. In this case, we run a transient simulation so, as far as I know, we have to import the shapefile first (without the recharge information), convert the shapefile to feature objects and then assign the time-series with the recharge values to those features (using text import wizard and selecting "transient polygon data"). But the conversion procedure creates a large number of features, since we have multipart polygons, and the recharge value assignment does not properly done.
  21. I agree with Hisham on this. There is no such concept as multipart polygon in GMS, as far as I know.
  22. Dear Chris,

    I have a WMS model with HEC-HMS for hydrological modelling. And I have defined "user hyetograph" in HMS Meteorological Method as the following format. But I have an error "the start date or time is invalid". Do you have any suggestion for this case? Thank you for your interest.

      The only suggestion I have is that you may be able to fix this by setting your computer to use "EN-US" as the locale setting when running WMS and HMS.

      Hope this helps,


  23. Dear isiarkos I would say you'd better include a "recharge code" field in your shapefile and use it to group polygons for recharge value assignment. Or, you can assign recharge values to the shapefile so that recharge values will be transferred to feature objects when you process your shapefile in GMS. This way, keeping multi-part features is not needed. I hope this helps
  24. Thank you very much for your quick response! Yes, that is exactly the case… The shapefile I imported contains multipart features. However, it is great of importance that these multipart features remain as multipart after conversion to feature objects (because they will be used as recharge zones). Therefore, I would like to ask: a) Is there a command in GMS (i.e. something like “single part to multipart features”) that converts back the new split features into multipart? OR Is there a way to prevent GMS from splitting multipart to single part features during conversion (when executing the command “shapes to feature objects”)? OR c) Is there another solution in terms of maintaining multipart features during conversion to objects?
  25. Your shapefile polygons may also be intersecting each other. Check them in GIS first and correct topological errors.
  26. Hello, this is interesting. Maybe there are 553 multipart polygons in the shapefile and when converting to feature object GMS performs multipart -> singlepart conversion. http://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/multipart-to-singlepart.htm
  27. Hello, I have imported a shapefile containing multiple polygons (553 polygons). When i tried to convert the shapefile to feature objects (command "shapes to features objects"), GMS creates more than 553 polygons-features (about 5000! polygons-features). For example, a single polygon with a specific ID, when converted, is split into multiple features with the same ID. How can this issue be addressed? It is important that during conversion to keep the same number of features as the initial number of polygons of the imported shapefile. Thank you in advance!
  28. LPF package

    Dear @Alan Lemon, Regarding your above reply; In my case similar to above, when I assign negative values for HK zones, the run results completely wrong. With the negative values I do can create key parameters by using "initialize from model". But the model doesn't run properly. On the other hand, with positive HK values I got a successfully finished run. However in this case, I couldn't initialize the key parameters from the model and don't know how to create parameters by hand. What should I do? Should I just add new parameters? If so, how does the program understands that these parameters indicate my assigned HKs? Best, Cansu
