Diploma thesis deals with the evaluation of threats on agriculture land by water erosion in the cadastral area of village Čikov before and after proposing of counter – erosion measures. For the calculation of erosion was used Universal equation (USLE) according to Wischmeier and Smith. The analytical operations leading to the calculation individual factors Universal equation and average long-term loss of soil by water erosion were made using the software ArcGIS, USLE2D and LS – Converter. Partial analysis are presented in the form of map outputs. In the interest area, after the calculating of the USLE, it was found that on 30,39 ha occurs very strong erosion which represents 4,73 % of the solved area. Strong erosion occurs on 36,56 ha (5,68 %), medium erosion on 229,94 ha (35,75 %) and slight erosion on 346,33 ha (53,84 %). Thanks to the proposed counter – erosion measures, very strong erosion in the interest area was completely eliminated. Strong erosion was reduced to only 2,52 ha (0,39 %) and medium erosion to 74,79 ha (11,58 %). Slight erosion increased to 566,21 ha (88,03 %).
