is a software package for carrying out precipitation-runoff simulations. The standard version of Kalypso Hydrology contains the computation module from the Institute of Hydraulic Engineering at the Technical University of Hamburg-Harburg. This model allows for simulating the entire land-based part of the water balance on the basis of given precipitation time series.
In this context the processes of snow storage, evapotranspiration, soil water storage, groundwater recharge, surface runoff, interflow, groundwater flow and wave translation in open channels are modeled.
