Particle Size Distribution and Small-Scale Bed-Forms on Sand Waves, Chesapeake Bay Entrance.
Abstract
The relationship between sediment texture and topography has been studied along five series of sand waves in Chesapeake Bay entrance, Virginia. Results indicate that two types of distributions are present: sand waves with coarse sediment on crests and fine in troughs, and sand waves with fine sediment on crests and coarse in troughs. Asymmetrical, migrating sand waves exhibit the first type; near-symmetrical, nonmigrating sand waves exhibit the second type. In general, bimodal sediment is present on crests of migrating sand waves and in troughs of stationary sand waves. There is a progressive decrease in percentage of biomodal samples in the Bay entrance sand wave field with distance to the southeast, the direction of net sediment transport.
