Description :
This study aims to attempt a sediment budget for the Holocene period using different approaches (quantification of present flux of solid material, of various sedimentary stores, and of rates of sedimentation), and to compare the values obtained by each approach. The mean sediment yield of the catchment will be compared to those of its various sub-basins. In the Négron catchment, the values of sediment yield differ widely according to the parameters used for calculation. Sediment yield varies by a factor of 1 to 5 according to the lithology of the sub-basin studied. During the Holocene it has increased by a factor of 6 as a result of the growth of agricultural activities.
