In earth science
a submergent coastline
is a coastline
which has experienced a rise in sea level, either due to a global sea level change, or local subsidence
. Submergent coastlines are identifiable by their submerged, or "drowned" landforms
, such as rias
(drowned valleys) and fjords. The Baltic
coastline, Chesapeake Bay
and southern England
are famous submergent coastlines.
