The distribution of sedimentary environments presents the limited domain of
deposits from "River Input", the flood tide wedge of "Atlantic Sediment", and
the extensive region of indigenous, recycled "Coastal Erosion Sediment" in the
Chesapeake Bay littoral environment. Studies by Miller (1982, 1983, 1987) along
selected reaches of the tidewater Potomac River showed that bluff retreat in
the littoral environment could be measured and modeled at as much as 0.5 to 1.0
m/yr. During the September 18, 2003 Hurricane Isabel storm surge of nearly 3 m,
as much as 8 to 10 m of coastal erosion was measured near some of Miller's
sites.
Storm-driven coastal erosion is the most extensive source of Holocene sediment
in the modern Bay. Although massive amounts were eroded from the terraces and
uplands during lowered sea level and cold climates, presently most sediment
eroded and transported from terrace and upland source areas has been stored on
slopes and alluvial bottoms of the Coastal Plain landscapes that surround the
Chesapeake.
