Watershed Description:Eight watersheds in the Guadiana basin, Portugal, totaling 2778 km^2, with sub-humid to semi-arid climate. Landcover is mostly annual rainfed crops, sparse cork oak agroforesty systems ("montado"), and shrublands. Soils are mostly low-depth and low-fertility lithosols. Ten watersheds in the Tejo basin, Portugal, totaling 1252 km^2, with humid to sub-humid climate. Landcover is mostly annual rainfed crops, commercial pine and eucalyptus forests, and vineyards. Soils are mostly Cambisols. 
Calibration Summary:Available data for calibration and validation included daily streamflow for 1980-1990 for most of the watersheds, and sediment-discharge curves for four watersheds in each basin. Calibration was performed with 5 years of data for half of the watersheds, evenly divided between 1980-1985 (dryer years) and 1986-1990 (wetter years). Nash-Sutcliffe efficiency for calibration was 0.85 for streamflow and 0.79-0.81 for sediment yield. 
Validation Summary:Validation was performed with the remaining streamflow and estimated sediment yield data, including 5 years of data in the calibration watersheds, and 10 years of data in the validation watersheds.Nash-Sutcliffe efficiency for calibration was 0.82-0.85 for streamflow and 0.71 for sediment yield. HRU-scale erosion and agricultural productivity were compared with long-term averages for the region.
