LISEM: Lisem Integrated Spatial Earth Modeller

LISEM (Lisem Integrated Spatial Earth Modeller) is a free and open-source software tool that aims to enable systematic integration of state-of-the-art numerical solutions for natural hazards both spatially (e.g. multi-hazard) and temporarily (e.g. feedbacks between events). It makes gathering and processing data easier and helps with dealing with uncertainties in complex simulations in a flexible and customizable manner. The modelling framework of LISAM treats data as sub-pixel fractions and allows multiple flow types (1D and 2D linked) and fully integrated erosion/hydrology components.
