摘要：It is known that effective erosion triggered by light rain, get local differences depending on the specific impact of these weather factors that are causal and conditional factors, geological structure and soil, vegetation, relief, etc. Therefore these reasons, the analysis of complex phenomena erosion must be made at the scale of basin or sub-basin, depending on the specific conditions of the site studied. In the Sub-Carpatien hills of Romania, the conditions are conducive to intense soil erosion event, the inventary in each river basin scale, considerable areas of degraded by such phenomena. This paper presents some aspects concerning gully erosion process developed on small torrential and agricultural watersheds as well as its impact on environment in Romania, with a case study located in one of the most affected areas by water erosion and landslides, namely Sub-Carpathian Curvature. The case study was carried out in the period 1992- 1999 on a number of 11 gullies located in the Slanic River Basin, which is a tributary of the Buzau River. After a short introduction on soil erosion process and its impact on environment, in general, gully erosion - in particular, in Romania, especially in the case study location, the paper presents some aspects regarding the main findings on some state and risk indicators of gully erosion developed in Romania on the small agricultural torrential watersheds. These indicators can be then easily used for soil erosion modeling.ca
