Abstract

In order to analyze the influence of erosion in the hydrological behavior of small streams, two similar catchments of the upper portion of the Velhas River were simultaneously monitored throughout a hydrological year. Rainfall, stream flow and hydrochemical data were sytematically collected. The results showed that the eroded catchment presented smaller baseflow rates and bigger but short-lived stormflows. This contrasting flow regime is attributed to the gully, which is causing the partial withdraw of the regolith and the exposure of weathered rock
