Excess sediment has been identified as a key issue for the River Rother, West Sussex, UK, a 350 km2
river catchment. The aim is to identify the severity, extent, possible causes and potential mitigation options available to reduce sediment into the river. Ten monitoring sites were installed on four major tributaries and the main channel of the River Rother to collect sediment in the river. Sediment will be compared with possible source soil samples to trace where the sediment originated.
