In Santa Maria, there are so many villages where conflicts dealing with earth occur. Such conflicts highlight problems associated with flooding, leaking and landslide. Considering this information, the objective here is to determine the erosion caused by the rain in Santa Maria, by establishing a critical rate through the regression's equation. The erosion provoked by the rain was determined according to Wischmeier & Smith's purpose (1956), expressed by E130,from 1980 to 2002. The relationship between erosion, flooging and landslide was established. The critical rate obtained from the EI30 was 48.55 Mj.há/ mm.h and trom the rain accumulated to the promotion of the events was 31,21 mm.
