Animation of delta progradation delta top-set sediments river input mean sea level delta foreset sediments delta bottom-set sediments The initial set up is of a river supplying sediment from the left into the ocean. The sediments deposited near sea level, where wave action and river forces can dominate will be different than the sediments deposited offshore, which can be dominated by storms and flood events, which will be quite different than sediments deposited in deeper and quieter waters. These three different types of sediments are labeled here as delta top-set sediments, delta foreset sediments and delta bottom-set sediments.
