Ria

A ria is a coastal inlet formed by the partial submergence of an unglaciated river valley.

Essentially, it's a drowned river valley that widens towards the sea. The resulting inlets are typically funnel-shaped, wide at the mouth and narrowing inland, with relatively shallow water.

They often feature complex branching patterns, following the original course of the river and its tributaries.

Rias provide sheltered harbors and are frequently associated with changes in sea level or coastal erosion.
