Environmental Science and Policy
The revised universal soil loss equation (RUSLE) was used to analyze potential high erosion risk areas in Northampton, Massachusetts, with a geographic information system (GIS) program. Soil units and land use features were reclassified with numerical values. Slope length and steepness were grouped together under one single index and calculated by means of GIS. These three factors were multiplied together and a map indicating high erosion risk areas was derived. Slope length and slope steepness have the biggest influence in determining where erosion will take place, and rivers and streams are at the highest risk for erosion. This erosion map should be considered for construction areas, as these areas produce high amounts of sediment, and based on this map the proper prevention or control should be implemented.
