Precise consideration of all peripheral conditions
The European Norm EN 752 (drainage systems outside buildings) and the ATV guideline A118 are taken into account
Determination of the surface run-off taking special conditions into account, e.g. evaporation, wetting, depression and flow length
Calculation of the rainwater run-off in the network using a dynamic transport model in mathematically exact consideration of all peripheral conditions
Up to 999 different and independent rainfalls as well as rainfall series, including drying phases, can be included in one calculation step (long term simulations are possible)
Definition of the rainfalls as constant block rainfall or variable model or natural rainfall
Roughness may be taken into account based on Prandtl-Colebrook or Manning-Strickler (open trenches or channel areas can be approximated)
50 pre-defined sewer cross-sections are available, up to 50 further individual sewer cross-sections may be defined
Various phenomenona and special cases can be taken into account, such as pressure flows, reverse flow directions, network depressions, complex networks, pump stations
Integrated network calculation of any common special structures, e.g. storm water tanks, overflow structures, sewer storage capacities, inverted syphons, pumps with their characteristic curves
Technical data
Maximum number of reaches: 1,000, 2,000, 3,000 or 250,000 depending on the module
