WebThe movement of sediment from the hillslopes may be transport and/or supply (weathering) limited. The most effective way to deal with the accumulation of fine sediment in aquatic habitats is to stop the excess at its source. This is feasible only for the sediment derived from accelerated erosion. WebThreshold channels, therefore, transport no significant bed-material load. Fine sediment may pass through threshold streams as throughput. In general, this throughput sediment should not be considered part of the stream boundary for stability design purposes, even if there are intermittent small sediment deposits on the streambed at low flow.
