Ongoing development
StormTac Web is continuously being developed with new data and methods, partly based upon feedback and requests from our users. The following development is going on right now:

1. Integration with GIS through automatic export of area data from GIS to StormTac Web, then through import of results (concentrations, loads and flows) from StormTac Web back to GIS for presentation on maps for each (sub)watershed area.

Users now have the ability to import area values per land use and subwatershed area from GIS.
This is the first step to facilitate the work between GIS and StormTac Web.
The next step is to visualize calculated data into GIS from StormTac Web. A work in progress.

2. Quantification and presentation of uncertainties regarding total pollutant loads before and after treatment, including specific uncertainties for precipitation, runoff coefficients and (sub)watershed area.
