SWIFT - Small Watershed Nutrient Forecasting Tool

software
posted on 2023-11-30, 08:11 authored by USDA ARS Grassland Soil and Water Research Laboratory

SWIFT (Small Watershed Nutrient Forecasting Tool), a component of the USDA/ARS Soil and Water Hub, is a web-based tool that allows the rapid estimation of sediment and nutrient loads from small watersheds for a given ecoregion in the US.

SWIFT can be used to estimate loads given relatively common information such as watershed size, landuse, and location. Estimated loads are provided as a distribution to illustrate the relative uncertainty inherent in the methods used. The web interface supports charting of precipitation, runoff, water yield, sediment, phosphorus, and nitrogen forecasts by ecoregion, watershed, and landuse (rangeland, cropland, urban, forest, pasture/hay) across the contiguous United States as annual averages.

SWIFT is based on the concept of export coefficients and delivery ratios. SWIFT uses export coefficients for major landuse categories in the US derived from SWAT (Soil and Water Assessment Tool) predictions. Delivery components are based on data derived from the CEAP (Conservation Effects and Assessment Project).
