The marked sites show considerable erosion phenomena due to precipitation events combined with sediment transport and soil accumulation, especially in waters, biotopes, construction facilities, etc. The damage notifications mostly resulted from water maintenance work. Due to the accumulation of the eroded soil material in the course of the water, considerable expenses for water maintenance are necessary every year. It is necessary to prevent further harmful soil changes from erosion and to provide for security measures.
