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. A comprehensive literature search and update of the database with more data on land use specific concentrations for many different substances, and with more reduction efficiencies as well as more irreducible concentration data per type of facility. These data will improve the accuracy of the predictions of pollutant loads and their treatment.
2. 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.
3. Quantification and presentation of uncertainties regarding total pollutant loads before and after treatment, including specific uncertainties for precipitation, runoff coefficients and (sub)watershed area.
