Title: Simulating slope failures and runout within a hydrological model: the OpenLISEM model.

 

Abstract: Hazardous land surface processes such as slope failures, resulting in mass movements, are a globally important hazard. Slope stability is influenced by hydrology and slope failure can thus be triggered by hydrological processes. In order to better predict and understand these hazardous processes, an integrated, physically-based approach is required. The free, Open-Source model OpenLISEM has been developed to simulate slope failure, estimate failure volumes and simulate the resulting mass movements, all within a full hydrological catchment model. This gives users a better indication of the physical causes of slope failure, and increases prediction accuracy.

OpenLisem simulated a fully physically-based hydrological cycle including interception, infiltration and simple ground water flow. Slope stability is estimated using the Iterative Slope Failure method. Finally, we use the two-phase mass movement equations by Pudasaini (2012) for runout simulations and interactions with water.

During this short course, a brief explanation of the algorithms and theories used in the OpenLISEM model will be given. The model itself will furthermore be given, together with test datasets of real events. This will allow for immediate practical experience in using the model.
