openLISEM a spatial model for runoff, floods and erosion

About openLISEM

openLISEM is a spatial hydrological model that simulates runoff, sediment dynamics and shallow floods in rural and urban catchments. It is an event based model, that can be used for catchments from 1 ha to several 100 km2. The model is designed to simulate the effects of detailed land use changes or conservation measures during heavy rainstorms. It is a model designed to be used in disaster risk management, not for long term estimates.
