DFG-Project FOR 581: Coupling of Flow and Deformation Processes for Modelling the Movement of Natural Slopes, Subproject 2: Numerical simulation of two-phase flow processes for natural slopes

Research group funded by the German Research Foundation(DFG) - Projekt number 5471717


The development of the movement of large hillslopes until failure is the result of complex interactions of hydrological, subsurface-hydraulic and soil-mechanical processes ranging over large space and time scales. As no reliable simulation methods exist today for such purposes, new solutions are suggested which bring together improved process models with coupling, averaging and upscaling methods while combining deterministical and stochastical approaches to take the complexity of the processes as well as the available data on the different scales into account. The tools which will be developed should first be verified using controlled experiments (benchmarks) before being transferred to a concrete field case for which a very good data set already exists. The central subproject is responsible for the coordination and administrative tasks of the researcher group. For the collaboration within the researcher group, a central internet-based information system will be set up to also serve as a platform for software-technical model couplings in the range of possibilities.
