AB: Soil moisture data collected from an in situ network and from satellite measurements were used to enhance estimates of streamflow for the Suwannee River Basin in the Southeastern U.S. Coastal Plain. Soil Moisture data collected from the AMSR-E instrument as well as the in situ data were used. The Soil Water Assessment Tool (SWAT) was used for the hydrologic simulations. Simulated stream-flow characteristics were compared to observed data from the Basin. Simulations using the observed soil moisture data were compared to those obtained without the soil moisture observations. Improvements obtained through incorporation of the observed soil moisture, based upon peak flow and volume estimates, were quantified. If successful, the real time estimates will be used to improve drought, flood, and agronomic production forecasts.
