Description :
The aim of this study is to analyze suspended sediment transport in a Mediterranean agricultural catchment under traditional soil and water conservation practices. Field measurements were conducted in Can Revull, a small ephemeral catchment on the island of Mallorca. This study uses continuous turbidity records to analyse suspended sediment transport regimes, construct and interpret multiple regression models of total suspended sediment concentration (SSC) and of SSC related to stormflow discharge, and assess the sediment loads and yields of 3 hydrological years (2004-2005 to 2006-2007). Multiple regression models identify rainfall intensity as the most significant variable in sediment supply. However, the historical use of soil conservation practices has also an impact.
