1165 | 604 | A simulation and visualization framework for the assessment of gully erosion dynamics: An application example from KwaZulu/ Natal, South Africa | Michael Maerker; Adel Omran

Gully erosion is known to affect soil productivity, and to limit land use in many parts of the world. To assess the susceptibility of soils_x000D_
to gully erosion, the triggering factors must be analyzed. We evaluated gully evolution dynamics in a test area sited in KwaZulu Natal, RSA. Therefore we developed a framework to simulate gully development using a numeric process based model and pre- and postprocessing modules implemented in Python –GIS. As input the topographic characteristics of the study area, soil properties, and measured runoff was used. The results show that the developed modules allow a successful data preparation, process simulation and spatial visualization of the obtained results in 2D and 3D as well as an analysis of gully evolution dynamics.
