The rainwater analysis is part of the DTM analysis-module of BBSoft®. It is performed by initially calculating the catchment areas with their respective surface within a DTM in order to conduct a rainwater analysis subsequently. That will convey you a realistic presentation of different rain occurrences within a DTM. With the aid of the drawing possible flooding surfaces can be recognized in advance with the selection of rain occurrence, the duration of this and the water amount per hour.
- selection of different scenarios of rainwater analysis, e.g. heavy or constant rain, shower or tropical storm (with the declaration of duration of shower and the respective water amount per hour)
- rainwater analysis report
- highlighting in the CAD, if a catchment was extended because of exceeding the min. drain height
- water depth and volumina of each catchment are inscribed in your drawing.
required modules: BB-VGR, BB-VDGM, BB-VHLN
