Evaluation of the dynamics of ravine erosion in the Grodarz stream basin stimulated by agricultural exploitation and communication system

Ravine erosion is a serious economic problem in Poland, especially in the loess uplands with high relative relief. Kazimierz Dolny, is one of the areas with the highest impendence of ravine erosion in Poland. In this paper it is shown that: with the current cultivation structure it is not possible to limit erosion processes to the level that will not be troublesome for Kazimierz; a basic method to protect ravines against erosion should be biological construction, that is introduction of suitable plant varieties in order to fix the most active ravines; it seems that some technical solutions cannot be avoided; material carried outside the ravine catchment should be directed via a special canal and culvert under the road to the purpose-built retention reservoir; only very considerate and complex preventive measures against erosion can limit this phenomenon in any significant way.
