摘要: Abstract The present study evaluates the applicability performance of Soil and Water Assessment Tool (SWAT) in small forested watersheds (less than 1000 km2). This open-source software is widely used investigations focused on water availability quality. Overall, SWAT model ranges between satisfactory to good. Normally, underestimates daily peak discharges. limitations are related accuracy climate data time period for validation. Watershed area, forest cover streamflow spatial distribution have an important influence modeling processes. from analyzed studies, we observed discharge a decreasing tendency, more pronounced towards end 21st century (up −54%). For surface runoff, was noticed same tendency up 41%. Regarding sediment yield, results vary within very wide limits. These findings according watershed location, scenarios adopted, eligible time.
