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 per 100 years, bayhead deltas across the Northern Gulf of Mexico experienced a phase of rapid landward retreat. Subsequently, those bayhead deltas stabilized and Alex Simms (UC Santa Barbara) and I are interested in better understanding controls on bay-head delta stabilization following rapid retreat. We recently published a paper in Geophysical Research Letters that shows bayhead deltas stabilize at tributary junctions as they are moving landward in response to sea-level rise. These results highlight the shortcomings of models that predict the impacts of sea-level rise by simply flooding topography (i.e. bathtub or passive-inundation models). One of those passive-inundation models is being served by NOAA. Play with the NOAA model online and then read our paper.
