The material exported from a watershed reflects its origin and the processes it undergoes during downhill and downstream transport. Due to its nature as a complex mixture of material, the composition of suspended particulate material (SPM) integrates the physical, biological and chemical processes effecting watershed material. This study will (1) use a sediment fingerprinting approach to quantify the composition and sources of SPM in the White Clay Creek Watershed in SE Pennsylvania and Delaware, USA, (2) examine longitudinal trends in SPM composition and source in first to fourth reaches of the White Clay Creek, (3) quantify the differences in composition and source with hydrologic variations produced by storms and seasonality.
