What is drowned river valley?
Due to either down warping along the shoreline or eustatic sea-level rise, rivers that flow into a sea or lake may drown or fill with sea water.
Former river valleys frequently display a dendritic network of tributary valleys and transform into deeply indented bays and estuaries.
Drowned river valleys are distinguished by the extension into an existing river system landward, river valley cross sections, shallow waters in the estuary, and corresponding bottom levels.
Estuaries of drowned river valleys are created when existing river valleys are flooded by rising sea levels.
The Chesapeake and Delaware Bays on the Atlantic coast are the largest drowned valley coasts in the United States.
