The dual drainage capability of VO-SWMM has found a useful application for water professionals looking to build integrated models that connect surface water with storm and sanitary sewer systems. Today, we are excited to release additional features and improvements that make the tool more relevant to users.
Customers can now leverage the precision allowance for the parameters of Dstore-Imperv and Dstore-Perv. Users can also find that they can set the default variables to be plotted on the time-series Plot Result window with ease.
What’s Improved with VO-SWMM?
- One key addition to the GIS toolbar is a dedicated selection button that is easily accessible. The new change allows users to click the button on the map to select the upstream/downstream/long section. Also, we have added more flexibility to how you can refine a selection within sub-catchments. For example, select connected sub-catchments.
- We have kept the rating curve the same but introduced a simple way to import curves via a CSV with two formats for each type of curve.
- To prevent using the same NHYD in the scenario, Smart City Water (SCW) has added a check in the error list to manage NHYD usage. The reason for this is first to keep consistent with the VO project (which does not allow the same NHYD) and second, this feature will be used later on to improve the scenario comparison, so if your old model cannot be run with the new installer, you can first check the error list.
- We have added real images of irregular transect curves and customized shape curves in the Shape Editor of the conduit so that users can see the real transect instead of a fixed image directly from the shape editor.
- The speed of surcharge analysis has also been improved so that for the long-term simulation, it can also generate surcharge analysis results.
- Additional fixes have been made to warnings and errors for conduit, outlet, weir, and orifice. SCW has also fixed the bugs of auto-connection of the catch basin and manual assignment of the catch basin.
How have VO & VO-SWMM both Advanced?
SCW has made changes to both engines to lead to advanced data insights of users. One of the changes being modifications to the Resource Library so that users can import the measured rainfall in a format of intensity, volume, and cumulative (for VO project, only Volume will be allowed; for VO-SWMM, all those three are supported as in SWMM5).
Presently, MTM has been added to the default coordinate system. It is useful to note that as long as the shapefile has a prj file associated, the software can detect the shapefile location automatically even though the default coordinate system is not the right one. A stimulating new design has been used (with video playing) for the progress bar.
Finally, SCW has also removed the bug of the Resource Library when upgrading from the lower version to VO6.2 while the performance of Sort Selected has also been improved.
