Sewer Network Hydraulics - Hydrological

Exact dimensioning and calculation

Manhole & reaches
Manhole & reaches
  • Determination of the surface run-off taking special conditions into account, e.g. evaporation, wetting and depression
  • Calculation of the rainwater run-off in the network using a transport model with follow-up determination of the water level lines
  • Up to 20 different and independent rainfalls can be included in one calculation step
  • Definition of the rainfalls as constant block rainfall or variable model 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
  • Dimensionings and verification calculations of sewer networks
  • Integrated network calculation of any common special structures, e.g. storm water tanks, overflow structures, sewer storage capacities

Technical data

  • Maximum number of reaches: 1,000, 2,000, 3,000 or 250,000 depending on the module
  • Maximum number of special structures: 4,000
  • Maximum number of flood curves: 500
  • Maximum number of nodes per network: 10,000
  • Number of catchment areas per reach: unlimited
