It is generally accepted that land use changes influence fluvial regime, especially generation of surface runoff, water discharge in water courses, and soil erosion. The disturbances in fluvial systems of old cultural landscapes caused by land use changes bring many difficulties in landscape management (floods, accelerated soil erosion, silting of river beds, etc.). The land use structure in the Trkmanka River catchment in the Czech Republic consisted until 1953 of fragmented plots (small patches of land, ribbons) and later has been changed into large fields with agricultural monocultures. The catchment is known for the highest values of soil erosion in the Czech Republic. Testing of common soil erosion models showed that they are not fitted for the catchment. A new model of soil erodibility is proposed in this paper.
