What is a Delta Landform: Formation and Types of Delta
As the flowing river reaches its final destination (lakes, ocean or sea), deposition of sediment takes place according to size of the grain. The first to be deposited is sand, which is the coarsest sediment. Since sand is the coarsest, it's deposited close to the mouth of the river. The finer sediment (silt, fine sand, and clay) is deposited next.

Sand Movement | Explore Beaches - UC Santa Barbara
Sand is washed ashore with waves and blown inland forming sand dunes. There are dramatic seasonal changes in sand movement: high-energy winter storm waves pull sand offshore; lower, gentle summer waves carry sand onto the beach. Sand flows into submarine canyons where it is stays for millennia (barring human intervention).
