Coastal Processes and Landforms

1. Depositional Featuresf) EstuariesWhat is a delta?Deltas form wherever rivers encounter standing bodies of water such as lakesor oceans. The sudden decrease in energy causes the river to drop itssediment load. Deltaic deposits therefore become finer grained the fartherout into the lake or ocean (distal edge). Across the delta, they are coarsest inthe distributary channels and finest away from the channels.
