Abstrakt

WinGeol/SedTec is a software package which simulates erosion and deposition in dependency of topography, fault movements,

lithological properties and sea level. Sediment transport such as mass and suspension flows are induced by elevation or concentration

differences between neighbouring cells. Grain size reduction during sediment transport is included into the model. The spatial distribution

of different rock types in the source area is used to model sediment composition. Rock types are characterized by their resistance to

erosion and grain size reduction during sediment transport. Input data for simulation include elevation, lithology, fault data and tabular data

from various data sets such as sea level curves and control points. Faults are defined by their geometry, geographic position, time interval

of activity, and a displacement vector. Examples simulated with WinGeol/SedTec include landscape deformations due to translation and

rotations of several fault blocks, erosion and deposition along a steep scarp and sediment transport and grain size distributions in

sedimentary basins such as the Pleistocene Mitterndorf basin in Austria.
