  1. Variable 2D roughness at low depths

    When applying direct rainfall onto 2D zones traditional roughness values do not typically apply, especially where the depths of water on the mesh element are very small. Often the workaround is to apply much higher roughness values in order to 'slow the flow'. It would be helpful to have a depth varying roughness that could be phased out as the water depth increases. This would put ICM in line with how TUFLOW and Flood Modeller Pro deal with the problem.

  2. GIM and infiltration zones

    When rainfall is applied to the 2D mesh with infiltration zones, it would be advantageous to have a GIM module that works with the infiltration zones, their infiltration model (i.e. Horton) and the sewer system to represent rainfall induce infiltration more effectively.

  3. Triangles browser

    Small triangles can slow down 2D simulations significantly. Currently, after creating a 2D mesh, I export the 2D mesh to a GIS software to check how many triangles I have below certain size and where they are. This helps me address the problem of small triangles efficiently. it would be helpful to have a similar functionality in ICM (i.e. triangles browser).

  4. Adjust mesh locally without remeshing all

    Adjust mesh locally without having to remesh the entire 2D zone.

    We are looking into this, but for the majority of cases it might be that there is already a significant improvement related to this with the new “Clip meshing” which was released with version 11.0 of the software, but in a prototype state, please ensure outputs are reviewed before use. The reason it provides an improvement is that it does a coarse mesh first (which is likely to remain unchanged if only small amendments are made) and follows this with a more detailed mesh after. It would be great to get any feedback you might have on your experiences with the Clip meshing and consistency of results.

  5. support (geo)tiff format as ground model format

    geo tiff is a more efficient format using less disk space, widely accepted.

  6. Inserting channels into topography

    Being able to insert channels into terrain rather than editing in 12D or other software would be more practical for smaller firms to turn around modelling ideas.

    Landscape packages allow terrain meshes to be manipulated with tools that sink into mesh easily. Channels and swales need slope, not simply vertical depression to model correctly. XPStorm allows 1D modelling but this isn't useful for presentations and Civil 3d and 12d are catching up quickly now that rational method is being phased out.

  7. As a user, I would like to have warnings about the landuse polygon size that will greatly slow down the performance in XPSWMM.

    Large number of land use polygons can greatly slow down the performance of XPSWMM, it can take up to 10 min to open and save a model. Ideally this issue should be fixed. Before that happens, if XPSWMM can warn the user for the large size of the landuse polygons, and provide links to ways to simplify the polygons or move landuse out as a reference layer, that will save the users lots of time.

  8. Create preset 2D inflow equation

    Similar to inlet capacity, have the ability to create 2D inflow equations relative to inlet size and control depending on weir or orifice curves. This will allow the user to increase or change 2D inflow control easier and more standardized.

  9. Include groundlevel as attribute in export network 2D mesh elements

    When you export a model to shape for example, only the element id is included. You have to run a simulation (for a second) and then exporting maximum reveales the element ground level. It saves time to add the mesh element level to the export. Although easy to add in GIS, the element area is also a handy attribute

  11. Apply RTC / observed values to Sluice Linear Structures

    At the moment we cannot move sluice linear structures in 2D. We're wanting to model a river entirely in 2D but the river is subject to a series of barrages that would require control. Therefore it would be essential to apply RTC and observed settings to the gates.

  12. Merge more than two polygon in one go

    Merging polygons representing for instance mesh zones can help reducing the number of triangles, particularly small ones, and reduce simulation time. The version of ICM I am using can only merge two polygons at the time. I currently do the polygon merge as part of my data pre-processing before importing the data into ICM as I can merge more than two polygons at the time. However, it would be useful to be able merge several polygons in one go in ICM.

  13. Reduce validation time of models with river banks or inline banks

    Current validation of models with bank lines takes a long long time for larger models, Up to several hours. My first guess is that checking a vertice bank level against the mesh level is the probelm. Same thing happens when you want to update ground levels from the mesh. This is also very very slow. It would help productivity speed if this could be reduced significantly

  15. Enable TIN Reference in Scenarios (Enable/Disable)

    All other layers in XPSTORM/XPSWMM are able to be deactivated for different scenarios.

    If you could allow for the Topography tins to be activated and deactivated (like Fill Areas, Elevation Shapes etc), this will allow for multiple scenarios (i.e. pre- and post-development) and minimise the complexities of trying to model two identical scenarios on two seperate models.
