In the Czech Republic, about 50 per cent of agricultural land is affected by water erosion that adversely influences soil productivity and the environment. That´s why the goal of this work was an evaluation of soil erosion danger in an arbitrary area. And secondly, if high erosion danger found, there was a task to make a proposal of suitable erosion control measures. The chosen area is called Hosín, located northly close to České Budějovice. There were fifteen profiles found in the area which are most likely to be in a danger of increased water erosion. These fifteen profiles were proved by two different methods of soil erosion evaluation. The RUSLE method - revised universal soil loss equation, and SMODERP {--} a simulation model of overland flow and erosion processes. SMODERP method showed all the proved profiles beeing not in a high erosion danger. Which means no erosion control measures are needed. The result gained by the RUSLE method was: by more than one third of examined slopes the estimate average annual soil loss raises above the limits. In this case the erosion control measures are necessary. Four different possibilities were proposed, the final one was combination of two erosion control measures {--} mulching and using a vegetative stabilization while the soil is uncovered. This kind of control measure was found to be the best one because of its low financial costs and easy implementation. On the other hand this control measure doesn´t restrict the farmer´s choise of the crops kind to grow. An objective comparison of the different results gained of the two methods wasn´t possible because of different enter data.
