Coastal Armoring in California - ArcGIS

Sand sources for these littoral cells consist of rivers, streams, and eroding coastal bluffs. These sources provide sand to the shoreline. Sand sinks are coastal features such as dunes and submarine canyons where sand is lost from the shoreline. Longshore transport or littoral drift is the wave force that moves sand along the shoreline.
