The importance of catchment characteristics in terms of intensive erosion runoff formation threat level
We located almost 130 000 critical localities near to urban areas where eroded material can enter the urban area. These localities were divided into five threat categories. Detailed modelling by WaTEM/SEDEM provided an extensive database of almost 130 000 micro catchments with outlet profiles threatened by intensive erosion runoff, and classified by five categories of threat for infrastructure damages.
