Sediment sources and sinks
WebIn general, sediment sources can be divided into two broad categories: (1) upland sediment sources, and (2) channel sediment sources. Upland sediment sources include various land-use and land-cover types: forest, cropland, pasture, construction sites, roads, etc. Channel sediment sources can include the streambanks, beds, flood plain, and gullies. WebFor a source circuit, there is a "switch" connected between the positive terminal and load, where it sources the current through the load from a voltage supply. For a sink circuit, there is a "switch" connected between the load and negative terminal, where the current sinks to ground through the load. Is my understanding correct or not ?
