Sewer Network Hydraulics - Hydrodynamic

Precise consideration of all peripheral conditions

Results list
Results list
  • 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
