Deltas' greatest importance to human activities, fish and wildlife lay in their characteristic highly fertile soil and dense, diverse vegetation. In order to fully appreciate the role deltas play ...
Deltas, like the Mississippi River Birdsfoot Delta, are river-dominated ecosystems. A river-dominated delta is only partially influenced by tides and waves. In this instance, wave energy dissipates before connecting with the coastline. These delta types are formed by sediment transport and deposition, also known as “fluvial processes.”.
