Understanding Sediment Sources, Pathways, and Sinks in Regional Sediment Management: Application of Wash Load and Bed-Material Load Concept

摘要

This System-Wide Water Resources Program (SWWRP) technical note describes how the concept of wash load and bed-material load can be applied to sediment transfer through the fluvial system for sediments derived from various bed, bank, gully, and catchment sources thereby providing a reliable analytical foundation for effective regional sediment management. The utility of this concept is demonstrated for Hickahala Creek, where erosion control features in the upper watershed were shown to have the potential to reduce sediment delivery to the downstream channel improvement project (Biedenharn et al. 2006).
