  1. Retriangulating to remove embankment

    DHendon is right. You can delete the triangles, but the scatter points at the triangle edges will remain in the scatter set and be triangulated again. You can turn on scatter points in the display options and see where the points are that are representing the embankment. If you select and delete those points and then triangulate, your embankment should be removed. Making a copy of the original is always a good idea. -Cody
  2. CE-QUAL-W2 - what am I missing?

    With the TIN turned on, is difficult to tell from just the image if your segment coverage has a lake boundary defined by feature arcs (Tutorial sections 4.1 or 4.2 show two ways to create the boundary). If it does have the boundary, WMS has a built in snapping feature so that if you click close (within a couple computer monitor pixels) to the boundary, it will snap to the arc. If it doesn't have the boundary already, you can create it by one of the methods in the tutorial referenced above and then recreate your segment dividing arcs keeping in mind that you must click close to the boundary arc to get it to snap. Regarding your other question, I believe that you still need to specify the single branch as the main branch and go through all the steps to create segments, even if no other stems exist. -Cody
  3. Problems With Pressure BC

    SRH-2D pressure flow structures are different than the other SRH-2D structures. For weirs, culverts, and gates it used to be recommended that you leave the materials for area between the structure arcs "unassigned", that is something that has recently changed. SRH-2D now will inactivate these areas when it runs the model, which is one less thing we have to try and remember to do now. Pressure flow structures actually need a material assigned to them because the area between the structure arcs (bridge deck) never gets unassigned. The 2D simulation results are computed in that area and represent the flow beneath the bridge deck. Try assigning a channel roughness to the polygon beneath the bridge and everything should run correctly. -Cody
  4. Diverting a Drainage Path

    Mike, This is exactly what I ran into the other day for a project I was working on. One possible workflow would be to edit the DEM using a feature arc. This is done by creating a new coverage, digitizing an arc through the center of the culvert (terminating it at the toes of the roadway embankment, or just beyond), editing the underlying DEM cells along the arc, and then rerunning TOPAZ. You can read more about this process in the online documentation: http://www.xmswiki.com/wiki/WMS:Editing_DEM_Elevations. An easy way to get the "Edit DEM Elevations" to pop up is to select the arc running through the culvert and then right click on it and select "Edit DEM Elevations". In the "Edit DEM Elevations" window, you can multi-select the first and last points in the plot by holding down shift and then you can press the "interpolate" button to linearly interpolate the elevations between the two selected points. When you select OK, it will edit the DEM elevations accordingly. Don't forget to rerun TOPAZ to pick up the new drainage path and then re-delineate your basins. If after doing the above, TOPAZ still does not pick up on the new drainage path further editing could be required such as widening the gap by repeating the process with a parallel arc or extending your culvert centerline further upstream/downstream. Let us know how it goes. -Cody
  5. Boundary Condition Issues

    Hi WIALLEN, Did you also extend your materials upstream? I have seen this message when my materials do not cover the inflow boundary. -Cody
  6. Scatter Data question

    John, As far as some of the more routine or general processes go in SMS like filtering, retriangulating, and merging go, my understanding is that most only utilize a single core. And as far as running models goes in SMS, there are some numerical models which allow parallel processing such as ADCIRC, ADH, and even TUFLOW has a form of parallel processing with their GPU solver, but there are also many which do not have that capability. Are you planning on using any of those models? The general set of hardware requirements are listed at the bottom of the following page: https://www.aquaveo.com/software/sms-surface-water-modeling-system-introduction You could stick with the 32G of RAM that you have, and match that with a processor with the fastest clock speed that your budget will allow, as mentioned in those general set of requirements. -Cody
  7. Scatter Data question

    It depends on the situation, really. If I don't need to do a lot of changes to the TIN, I like to convert it to a raster format. High resolution rasters are handled very efficiently in SMS and with the realease of SMS 12.3, you can now use rasters for meshing and grid creation. Raw .LAS lidar files can be brought in as a raster or external software can be used to interpolate points to raster. If the TIN data requires extensive edits and changes and I have to keep it in a TIN format, then I look for ways to cut the points down which could include filtering the data or deleting the outer extremities of the data which lies outside my project area. Are any of those possibilities for your situation?
  8. Scatter Data question

    John, SMS has tools to filter out scatter points, see the documentation below: http://www.xmswiki.com/wiki/SMS:Scatter_Data_Menu#Scatter_Commands You provide a filter angle which helps decide the extent of the filtering. I usually vary the angle a bit until I like what I am seeing for the remaining scatter set. So you may want to make a duplicate to preserve the original, if you do not end up liking what the filtering options give you. I will add that I have run into large scatter sets where it also takes a long time to filter. These larger datasets end up chewing on the data while requiring a lot of RAM during the process. If the computer you are using doesn't have a significant amount of RAM, it will likely take a lot longer. If these scatter sets were created from LiDAR tiles, there are other options for bringing them in that might work for you which handle the data more efficiently, processing wise. Let us know how it goes. -Cody
  9. SRH-2D Materials Coverage Errors

    Hi Gary, We have recently encountered the "error renumbering..." message while working with some files of our own. It seems to happen while modifying the polygons as you have mentioned. This has been reported as a bug and will be fixed in the very near future. I have not seen any issues so far with polygon assignments being different as shown in the task bar or any 5-15 second delays in opening the materials dialog, but we would like to investigate this a little more so we can resolve any issues that may exist. If you still have the files showing this behavior, and would be able to share them, you could contact our technical support team at support@aquaveo.com. They can set up a link to upload the files and look into this a bit further. -calberts
  10. You could use the split nodestring command. This option is found in the "Nodestring" menu and is usually dimmed and unavailable for use. To un-dim this command and use it, use the select node tool and select the node along the nodestring where you would like to split the nodestring (so in your image above, this might be node 1). With a node selected, you can then choose Nodestring | Split and the nodestring will be split at the node. Of the two resulting nodestrings you can delete the one that you no longer wish to have. I tested this on one particular nodestring and it preserved the nodestring inputs within both of the resulting nodestrings. A similar command is the Merge nodestrings command which is available when two nodestrings are multi-selected. I hope this helps. -Calberts
  11. Interpolation of cross sections with node strings

    Hi Tertia, I am not aware of an option to interpolate cross sections with nodestrings. But I am confident there is a way to accomplish what you are trying to do. The most efficient way is dependent on what you currently have. It sounds like you have a scatter set surface right now and cross section data in some format. In what format do you have your cross section data? (XYZ text file, CAD file, Shapefile, etc)
  12. SRH2D Point Shapefile Output

    NicT, SMS will allow you to create a text file including node point locations and computed datasets in the "Save as" menu. 1. Select the Mesh to make the mesh module active 2. Select "File | Save As..." 3. Change the "Save as type:" to "Tabular Data Files (.txt)" 4. Give it a name and click Save. 5. Specify the number of columns, Precision, and Delimeter type 6. In the "Data" row at the bottom select the "Data" button for each column to choose a mesh dataset that will be written to the text file. You can choose "X" and "Y" which are the coordinates of each node, and then choose other datasets to add the the other column(s) (which will be however many columns you chose to include) 7. Select OK when finished setting up the columns and it will create the text file with the columns configured how you set them up reporting data at the node locations. I have used this quite a bit to transfer mesh data to other programs and excel. -Calberts
  13. CulvertĀ“s parameters in SRH 2D

    Hi, For the FST culvert, which is called "Culvert" in the SMS SRH-2D Linear BC assignment window, your best reference will be the Bureau of Reclamation's Technical report SRH-2016-09 which can be accessed at the following link: https://www.usbr.gov/tsc/techreferences/mands/mands-pdfs/ModelingIn-StreamStructuresInternalFeaturesWith SRH-2D_02-2016_508.pdf That paper also provides detailed description of all other structures in SRH-2D. For the HY-8 culvert, which is called "Culvert HY-8" in the SMS SRH-2D Linear BC assignment window, you will most likely find the HY-8 user manual to be most helpful. http://wmsdocs.aquaveo.com/HY-8_UserManual_v7.5.pdf -Calberts
  14. Scaling set as bathymetry when building a mesh

    Thank you for posting this. We are unaware of any problem such as the one described at this time. However, we would like to run some tests to try and replicate it. Could you send an email to our support team at support@aquaveo.com with a description of this problem and details of your SMS setup? This will help us narrow down our testing. Please be sure to mention which SMS build you are using and any pertinent information such as the steps you take to assign the bathymetry and scalar paving data.
  15. Reverse water flow at Downstream

    Fahad, Thank you for posting this. Could you provide more information on this so we can adequately answer your question? What type of boundary conditions are you currently using? What is it that you are wanting to see the model simulate? Kind regards, calberts
