Precipitation, discharge and suspended sediment concentrations were continuously measured during over 10 years at the 4 km2 Vallcebre experimental catchment (South-Eastern Pyrenees). The results show a complex response, as small and moderate events show large sediment concentrations whereas large events show lower sediment concentrations but much larger discharges and longer durations. On the long run, the actual role of major events is difficult to assess not only because their low frequency but also because measurement errors are larger during them than during small frequent events. |
