Where do coastlines stabilize following rapid retreat?

Bayhead deltas are located where rivers flow into estuaries.  They have broad low-elevation plains that are sensitive to small increases in the rate of sea-level rise.  In the past, when sea level was rising at a rate of 1 m … Continue reading
