Nested, Spatially Distributed Annual River Channel Sediment Budgets Pinpoint Sediment Sources and Identify Downstream Sediment Transport Pathways

Traditional watershed-scale sediment budgets sum sediment sources such as bank erosion (BE) and headwater tributary inputs (HI) and subtract sediment sinks (floodplain deposition, FD) to compute watershed sediment yield (Qs). This approach, however, d
