<Li> Deposition of sediment on shore </Li> <Li> Gullies through the land </Li> <P> This sediment then enters the coastal system and is transported by longshore drift . A good example of the sediment budget and longshore drift working together in the coastal system is inlet ebb - tidal shoals, which store sand that has been transported by long - shore transport . As well as storing sand these systems may also transfer or by pass sand into other beach systems, therefore inlet ebb - tidal (shoal) systems provide a good sources and sinks for the sediment budget . </P> <P> Sediment deposition throughout a shoreline profile conforms to the null point hypothesis; where gravitational and hydraulic forces determine the settling velocity of grains in a seaward fining sediment distribution . Long shore occurs in a 90 to 80 degree backwash so it would be presented as a right angle with the wave line . </P>

What depositional feature can be used to determine the direction of longshore transport
