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