Hydraulic stormwater circulation

The flood map method can only be used to calculate the depth of depressions and hollows, the size of their catchment areas, as well as the flow routes. Using e.g. photo analysis and/or GIS analysis of basic data, the calculations can factor-in paved areas. This makes it possible to perform hydraulic stormwater calculations for observed precipitation events. The calculations can be performed as 1D or 2D stormwater calculations, i.e. calculating the upstream runoff either as one-dimensional channels or as two-dimensional surfaces.
