摘要: The unit Hydrograph method is extended to sediment graph analysis, thus yielding a graph. applicable small uniform watersheds where the main contribution suspended transported in drainage channels as result of runoff derives from upslope erosion, that is, wash load and not entrained bed material. Bixler Run, load-producing watershed near Loysville, Pennsylvania, was used data source deriving graphs. hydrographs concomitant graphs are generally parallel shape coincide during peak flow.
