Shore erosion as a sediment source to the tidal Potomac River, Maryland and Virginia
Andrew J. Miller
1987, Water Supply Paper 2234-E
The shoreline of the tidal Potomac River attained its present form as a result of the Holocene episode of sea-level rise; the drowned margins of the system are modified by wave activity in the shore zone and by slope processes on banks steepened by basal-wave erosion. Shore erosion leaves residual...
