Integrated Erosion Tool (IET) Services

The Integrated Erosion Tool (IET) services enable the analysis of soil erosion by water and wind using the Revised Universal Soil Loss Equation (RUSLE2) and Wind Erosion Prediction System (WEPS) models developed by the USDA Agricultural Research Service (ARS). The services support a geospatial IET application extending the resource analysis functionality of the USDA Natural Resources Conservation Service (NRCS) Customer Service Toolkit (CST) deployed to 2,800 agency county offices. CST has been used for several years to manage more than 1 million conservation plans on 300+ million acres of agricultural land. IET services also support the Keystone Center's Field to Market Initiative involving a consortium of public and private sector food supply chain organizations.

IET services calculate sheet/rill erosion, wind erosion, PM10 air particulate matter, soil condition index (SCI), and soil tillage intensity rating (STIR). In the coming months the ARS Water Erosion Prediction Project (WEPP) model service will be added providing concentrated flow erosion, gully erosion, and sediment delivery calculations. The Rangeland Hydrology and Erosion Model (RHEM) model service will calculate soil erosion by water on rangeland.
