  2. Hello! I'm constructing a GSSHA model of an urban watershed and in my watershed there are some open channels that flow into closed conduits (pipes/storm sewer) and then flow back into open channels. I've successfully run some GSSHA models including a GSSHA Storm Drain SUPERLINK coverage and I can get the storm sewer to discharge to a stream arc or the overland grid. However, after running the model and looking through the user manuals, it appears that the SUPERLINK storm sewers only receive water from the overland grid and not from the stream arcs. Is there any way to set a stream arc as the inflow to a pipe? Or is there a way to discharge the flow from a stream arc to the overland grid cell so it can then be picked up by the SUPERLINK storm sewer? Or maybe is there some way to do what I want by modelling the closed conduits as culverts (I couldn't find much information on including culverts as hydraulic structures in GSSHA)? Thanks! Conrad

    draining water to the ground using canals

    Thank you Sean. I will try this and let you know. Appreciate your prompt response.

    draining water to the ground using canals

    Increase the recharge in the cells where you are simulating the canals. Just an option - may not be exactly what you are looking for.

    PROBLEM IN DISPLAY OF WIND VECTOR USING SMS

    THANKS A LOT TODD THIS SUGGESTION WORKS WELL......

    PROBLEM IN DISPLAY OF WIND VECTOR USING SMS

    Hi smita, I believe what is going here is that your contours are covering the vectors in the upper portion of your mesh. To make your vectors show up above the contours, you can either add transparency to the contours in the display options or change the Origin/Offset options in the vectors tab of the display options to tell SMS to draw the vectors at a higher location. Hope this helps.
  7. Hi All, I would like to check the effectiveness of using canals to draining water into the ground with the gravity (opposite of drain) without using injection well. How do I model this in GMS modflow? Please let me know your suggestions. Thank you, Lalith

    SMS Saving Vertical Projection for a LIDAR file

    I had a similar problem, my x and y stayed as feet, but SMS converted to z data to feet. The problem was that the raster data was already in feet so my imported data was off by a factor of 3+. After playing around for some time trying to reproject, etc.. etc... I ended up using 3D Analyst and using the Raster Math tool to adjust my z values.
  9. Dear Forum, I am attempting to add non-vertical boreholes to a preexisting XS2D profile using the tool in the XS2D editor but I haven´t had any luck so far. If someone could detail a simple workflow for this task that would be greatly appreciated. The tool help information indicates the following: The feature classes should be in the same feature dataset. The XS2D_Catalog should be set up previously with a XS2D Line feature class, and an XS2DType of "Boreline" for the SectionLine the tool is working off of. The tool works off of a selection set of Well features near the SectionLine feature used in running the tool. With respect to the second point, my question is how to create a second Boreline XS2DType in the XS2D_Catalog that allows for entry of azimuth and dip data, in addition to the first Boreline XS2DType for the already existing vertical wells. One thing I tried to do was copy the Boreline Type and then add fields for azimuth and dip so as to later import this data through the text importer, but the application didn´t let me add fields. The other thing I tried to do was to generate 3d borelines in ArcScene according to the "Non-Vertical Boreholes" tutorial (which I was able to do) and then import the feature class to the same feature dataset from where I had generated the XS2D profile (according to point #1) so as to later generate the non-vertical boreholes in the same profile, but the application did not allow me to import stating that the coordinate system did not coincide (although it does). Any advice on how to carry out this procedure is very welcome Regards, Marlin

    Reprojecting a GRID

    You can do this manually by editing the origin and rotation of the grid in the Grid Properties dialog.

    What is actually meant by Boundary stress?

    I have got the answer. Boundary stress is a standard output of sms and it represents bed shear stress based on frictional resistance of flow. It is depth averaged value. And, of course, I can calculate bank erosion using fine mesh.

    NLCD

    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

    NLCD

    In the past, I have downloaded NLCD data from the National Map website. The National Map website now has a link to the MRLC website, and it appears the NLCD information is only available in a .rrd file which covers the entire contiguous United States. Can the .rrd file be used in WMS?
  16. Whenever I am plotting wind vectors using the new SMS versions like 12.0, 12.2 or even 12.3 the complete wind vectors are not displayed over the domain . Here I am attaching the .png file of such plot where the right hand side wind vectors are completely not visible . it will be nice if somebody can guide over the issue.

    SRH-2D Monitor Lines

    I believe it is just a straight average.

    SRH-2D Monitor Lines

    Good morning, Does anyone know how SRH-2D monitor lines work. I am wondering how they calculate the average water surface elevation? Is a straight average or flow weighted somehow? Also how is the flowrate calculated? I find they never match flux calculated with an identical observation line. Thanks, Phillip

    Reprojecting a GRID

    Hello, I am using a model which was previously built using the conceptual model approach. However I reused the active/inactive cells conditions in another grid model. The Grid model is not projected. Is there a way I can reproject my Grid model according to the projection of the first model? Thanks

    Head is computed for dry cells (below bottom of the cell)

    After doing some reading I realized that these observations are a result to the the MODFLOW-NWT version which indeed calculates the head for dry cells but readjusts the conductance so that no flow occurs between dry and wet cells. In addition, the storage formulation was modified for unconfined conditions such that there are no changes in storage for head changes that occur beneath the cell bottom.

    What is actually meant by Boundary stress?

    Is Boundary stress given by SMS after postprocessing the flow induced stress? Is it depth averaged value? Can I calculate bank erosion by this value? ---Shahidul Islam.

    Use Raster file as a Landuse file in TUFLOW

    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

    Local Refinement

    Sounds like refining the mesh. The best way I know to refine a mesh is to add an arc if it is a linear feature you are trying to represent, and then adjust vertices until you have the refinement you want. If it is a general area, you can place a node, right click it and select refine attributes, then make it a refine point. There are other ways to refine your mesh, but they will do it to the entire mesh. Hope this helps.

    Local Refinement

    I read from a book that "Where there is a sharp change, high resolution should be used there." I think, this is talking about refining mesh.
  26. Donald Hendon

    Local Refinement

    Can you be a little more specific? Are you talking about refining scattered set data ,or mesh elements, or what?
  27. Shahidul Islam

    Local Refinement

    I want to know about local refinement and how can I do it by SMS software?
