| Zusammenfassung |
| The use of Cellular Automata is extended in various disciplines for the modeling of complex
system procedures. Their inherent simplicity and their natural parallelism make them a very
efficient tool for the simulation of large scale physical phenomena. We explore
the framework of Cellular Automata to develop a physically based model for the
spatial and temporal prediction of shallow landslides. Particular weight is given to
the modeling of hydrological processes in order to investigate the hydrological
triggering mechanisms and the importance of continuous modeling of water balance
to detect timing and location of soil slips occurrences. Specifically, the 3D flow
of water and the resulting water balance in the unsaturated and saturated zone is
modeled taking into account important phenomena such as hydraulic hysteresis
and evapotranspiration. The infinite slope analysis is coupled to the hydrological
component of the model for the computation of slope stability. A test case of a
serious landslide event in Switzerland is investigated for the verification of the model. |
