HYSTEM-EXTRAN is the classic option for hydro-dynamic simulation of sewer systems: in the complete re-visited version 7 (among others) this expands for simulating pollutant loads coming from the surface. Use HYSTEM-EXTRAN 7 for proving hydraulic efficiency, for example for master plans, as well as for new planning and replanning of sewer networks.
With the hydro-dynamic rainwater, runoff and pollution load system HYSTEM-EXTRAN, sewer system simulations with design storms as well as long-term series simulations can be carried out. Besides the classic sewer system simulations, HYSTEM-EXTRAN can be used even in other related fields, thanks to its flexible structure. Combined with the rule interpreter CONTROL, control strategies for sewer systems, for example, can be developed and checked.
This clearly-arranged software concept contains the following modules:
HYSTEM-EXTRAN 7 supports the following simulation methods:
HYSTEM-EXTRAN 7 stores all incoming data (network data, rainfall data, special profiles, etc) in a model database and all simulation results in a results database. Results databases from various simulation runs can be easily compared. The connection to the graphical modules GIPS and FOG is thus implemented. So, HYSTEM-EXTRAN results and findings can be used, for example, for large-scale themes and further evaluations.
