Ria
A drowned river valley in an area of high relief; most have resulted from the post-glacial rise in relative sea-level (based on Allaby & Allaby, 1990). As defined for the EC Habitats Directive, 'rias and voes' are "drowned river valleys (not of glacial origin) with relatively deep narrow well-defined channels which are predominantly marine throughout".
