  1. They don't have all the builds on their downloads page, as you have noticed. Sometimes you can reach out to tech support (support@aquaveo.com) and they may be able to send you the build you are looking for. It's worth a try! -Calberts
  2. WIALLEN, are you possibly using a Community License? If so, one of the limitations is the inability to save a shapefile. https://www.aquaveo.com/software/sms-community -Calberts
  3. pagesk, if you abort the simulation, you would lose the results since SRH-Post would not run and give you the final _XMDF.dat file. I found myself in a similar situation once and found that you can override the original simulation end time by using the _DIP.dat file. See Appendix C of the SRH-2D user manual Page 91 https://www.usbr.gov/tsc/techreferences/computer software/models/srh2d/downloads/Manual-SRH2D-v2.0-Nov2008.pdf The process would look like this: 1. while srh is running, open the _DIP.dat file in a text editor 2. copy and paste in the start and end lines as well as the command to override the total simulation time (see below for example, this would override the simulation end time and make it stop at hour 9) $DATAC TOTAL_SIMULATION_TIME = 9.0 $ENDC 3. Save the text file, SRH will then read it and override the end time Note: If you will run the simulation again and do not wish for it to stop at that override time, you need to manually delete the lines in the file added in step 2 above, or delete the _DIP.dat file. -calberts
  4. Fcernst, you likely have already moved on from this question, but for sake of providing an answer for others out there that may be facing a similar question, the elements are generated based upon the spacing of the arc vertices and nodes. To see a great demonstration of this, check out the meshing tutorial at the link below. http://smstutorials-13.0.aquaveo.com/SMS_MeshGeneration.pdf -calberts
  5. Rob, I don’t believe SMS 12.3 has the capability of converting to raster, someone correct me if I’m mistaken. I do happen to know that functionality was added to 13.0. In 13.0 you first convert the mesh to a scatter set by right-clicking on it and converting to scatter and then you right click on the scatter set and convert it to a raster. You can set the desired resolution and it will save out a geotiff. If you haven’t done so already, you could evaluate SMS 13.0 with a free trial and check it out. Or I’d also suggest looking into renewing your maintenance since 13.0 comes with some other useful features like improved LiDAR processing. calberts
  6. Donald is right, you may have better luck with using the source arc redistribution for those bends in the channel. See the following wiki for more details: Source Arc Redistribution The problematic elements are likely the tight group of skewed elements I've circled in the image below: The other elements that are flagged could also be improved (and will be with source arc redistribution), but I wouldn't expect them to be the problem. -calberts
  7. Is this for a line or point type obstruction? In general, for both types of obstructions you can set the height by changing the Z value(s) associated with the line or point . The thickness attribute that is assigned to it then is measured vertically upwards from that elevation. Cody
  8. Thanks for sharing the .srhhydro file, I believe Aquaveo has fixed this issue in SMS 12.3. As a workaround in SMS 12.2 try the following: 1. Export the simulation (Just choose "Export SRH-2D" and not "Save, Export, and Launch SRH-2D") 2. Open the .srhhydro file in a text editor and modify the last 5 lines to match the following lines: LinkNodestrings 1 1 2LinkFlowType 1 CONSTANTLinkConstantFlow 1 70 ENLinkLagtimeMethod 1 SpecLinkSpecifiedLagtime 1 3600 3. Save the changes to the .srhhydro file in the text editor. 5. Launch the simulation (Just choose "Launch SRH-2D" and not "Save, Export, and Launch SRH-2D") With these changes SRH should be good to run. Let us know if it still has issues. -Cody
  9. Typically when SRHPre asks for “on screen input” it means that a required variable for the structure has not been provided. This usually means that something went wrong exporting the simulation and the variable was not written to the .srhhydro file or It was written in an incorrect format. Could you include a screenshot or copy of the text in the .srhhydro file? Also, what version of SMS are you using? -Cody
  10. JKM, As you are to the point of running the model and already have a mesh created, the scatter set won't have any influence on the model since the elevations from the scatter were a piece of the mesh building process. The main thing you would want to verify is that if the scatter set does have problems, those problems have not been transferred to the mesh. If you review your mesh and all looks good, then the -999 values for the WSEs likely are caused by something else. You could review the materials coverage to make sure you have materials polygons covering the entire extents of the mesh and that those polygons have a material type other than "unassigned" that have been assigned to them. Aside from the materials, the only other thing I can think of is that the model possibly needs to be ran for a longer duration of time? Let us know! -Cody

    B. Horrocks, The .img file that comes with the .rrd file you downloaded is supported by WMS and can be loaded in. However, due to the size of the file you will run into a snag when converting the .img to a native land use grid that WMS can use for computations. If you can crop the raster down to your area of interest using an exterior GIS program, that would be necessary. This is assuming you want to use the NLCD 2011 data. If the land use in the area you are working in hasn't changed much since 2006, WMS can download a cropped subset of the NLCD 2006 data by using the web services. I'd recommend using the Get Data From Map button and selecting it from the list of web services that pop up. In the near future WMS 11.0 will be released to a beta version. In that version the same capability described for the NLCD 2006 data will apply to the NLCD 2011 data, which will make it much easier to use the 2011 data. -Cody
  12. Fahad, Currently, SMS only allows the specification of materials for TUFLOW as polygons. It is possible that there may be a way to manually modify in the input files after SMS has written them which will allow you to use a raster file. So you may want to post this question on the TUFLOW user forum as well and see what suggestions you get from them. https://www.tuflow.com/forum/ -Cody
  13. Isaac, If I'm not mistaken, that may just be another way to tell SRH that you want to use a restart file. I have never done it that way, but from the manual it appears that you want to do either "IREST=0" for no restart file or "IREST=1" to use a restart file. You would then have a file alongside the simulation .DAT file which matches the casename of the .DAT file but has an "_RST.dat" at the end of it. Below is a snippet from page 91 of the SRH Manual Either way it seems like this is just an alternate way to specify that you want to use a restart file. Let us know if it works. I still think that the restart file should have the sediment info included in it, so let us know if it does not appear to have such. -Cody
  14. I do work for Aquaveo. Thanks for letting me know.
  15. Thanks for checking that. SRH-2D will interpret the geometry in SI units if the horizontal projection unit is in meters. So what I believe is happening is that SRH is interpreting the ~330 ft mesh elevations as 330 meters and the TW values are much much higher than the 330 ft values in the HY8 table. I would recommend making your horizontal and vertical units consistent by using the "Reproject All" function to convert all your horizontal units to feet or all your vertical units to meters, whichever one fits the situation. After doing that you should be ok to run SRH and even raise your timestep back up. -Cody
