Abstract

The solute and suspended-sediment load following 5 rainstorms (2005–2007) with varied intensities were studied at the Vernegà experimental watershed, north-western Spain. This study investigates the capacity of each land-use (forest and agricultural area) to yield water, suspended sediment concentration (SSC) and dissolved solid concentration (DSC). Results showed that the agriculture area produced significantly greater mean DSC than in the forest area. Geographic information system (GIS) spatial data layers of the watershed were produced to determine the relation of tracks, landforms, slopes and forest management to SSC yield in the forest outlet during the 5 rainstorms. Agriculture practices are the main cause of soil erosion at the study area
