WebJun 16, 2024 · How does sediment size change along a beach? On some beaches, sand grain size composition varies with distance from the water. A greater proportion of finer, smaller sand grains may be pushed higher up the beach by waves or by wind, whereas larger, coarser grains are deposited closer to the water. WebWaves and currents sort the sediment and move it alongshore as a river of sand, predominantly to the south along the California coast. Coarser material remains closer to shore. Below mobile surface sediments, a …
