Runoff estimation in southern Brazil based on Smith's modified model and the Curve Number method

► We model surface runoff for different soil classes and management system. ► Runoff can be estimated based on rainfall intensity, land slope and soil porosity. ► The Smith's modified model estimates runoff for no-tillage management system. ► Curve Number overestimates the cumulative runoff for...
