AB Intensity of snowmelt erosion was computed for cadastral areas of Pohořelice, Strážnice, Kuchařovice, Holešov, Dukovany, Vizovice, Velké Meziříčí and Bystřice nad Pernštejnem on the base of 1980-2006 data for the period November to March. Mean long-term soil loss was estimated according to ZACHAR (1981) equation on the base of average rate of snowmelting, amount of melting water, outflow and infiltration characteristics, topographical factor, soil factor and vegetation factor. For the studied localities the average rate of snowmelting varied from 2.29 mm.day<sup>-1</sup> to 7.90 mm.day<sup>-1</sup>. Also amount of melting water reached the maximum in Bystřice nad Pernštejnem in dependence on climatic region (6.11 cm of water column). Outflow and infiltration characteristics varied from 0.94 to 1.14. High value of topographical factor (10.5) was assessed in Vizovice. Soil factor was estimated according to main soil unit from Estimated Pedologic-Ecological Unit EPEU. Its values varied from 0.31 in Velké Meziříčí to 0.47 in Holešov. Vegetation factor varied from 0.2938 in Vizovice to 0.4881 in Kuchařovice. Average soil loss as a consequence of snow melting varied in interval from 0.61 t.ha<sup>-1</sup>.year<sup>-1</sup> in Pohořelice to 30.08 t.ha<sup>-1</sup>.year<sup>-1</sup> in Vizovice.
