Deltas form when the volume of sediment deposited at a river mouth is greater than what waves, currents, and tides can erode. Deltas extend the coastline outward, forming new land along the shore.
Delta Landforms - U.S. National Park Service
Wave erosion and strong longshore currents disperse the sediment away from the river mouth, producing a relatively straight coast with only slight seaward bulges of the shoreline. In some regions, a large tidal range overshadows river and wave effects, creating tidal-dominated deltas.
