A rainfall simulator is a common laboratory tool for soil erosion research. Typical objective of the rainfall experiments is the evaluation of various factors on soil erosion processes, such as the effect of rainfall intensity, rainfall duration, soil characteristics, soil management, crop residues on the soil surface, plot’s slope and length.
The article deals with the development of agriculture bare soil surface using the stereophotogrammetric method. It describes and compares the development of selected soil characteristics investigated on four types of field cultivation.
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.
