Sediment diagram, from source to sink
Sediment is the sand, mud, and pebbles that were once solid rock. Sediment flows in tributary streams and river channels of the Skagit, from the Cascade Mountains to Skagit Bay and Puget Sound. Source: Erosion from slopes and migrating river channels generate a lot of sediment. Transport: Rivers move sediment downstream. Sink: Sediment is deposited across natural river deltas and floodplains. Diagram courtesy of Skagit Climate Science Consortium.
