Abstract

In-channel sediment storage has been studied in a ∼3-km channel length reach of the River Isábena during an average hydrological year (2007-2008). This river is located at the Southern Pyrenees and the channel network flows through an area of extremely erodible materials producing an enormous amount of suspended sediment. Sediment storage values obtained in the study reach have been extrapolated to the whole main channel. In-channel storage shows both temporal and spatial trends. In relation to the former, sediment is continuously accumulated during low-flows while the latter shows that sediment accumulation increases in the downstream direction. Results suggest that the fine-grained sediment stored in the channel may represent an important component of the suspended sediment budget of rivers draining highly erodible materials such as the River Isábena
