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.
A submergent church definition –: One that through prophetic natural processes abandons the traditional drowning, gasping for life, church structure that is being overwhelmed from the rise of an inevitable tsunami of cultural change and in so doing discovers gills with which to flourish below and a part from the submerged surface of the institutional church.
