The influence of wind waves and tidal currents on sediment resuspension in Middle Chesapeake Bay
1985
Resuspension of bottom sediments by waves and tidal currents was investigated in three characteristic environments of middle Chesapeake Bay (shallow platform, deep platform, and main channel). In the shallow near shore platform wind waves frequently resuspended significant amounts of sediment, some of which was transported offshore. In both the shallow and adjacent deep platform regions, tidal currents were too weak (<20 cm cm/sec) to resuspend bottom sediments. In the main channel, peak current velocities were substantially stronger (40 cm/sec), but were still not competent to erode the bottom. The stability of the bottom in this area is related to the activities of the benthic organisms which are influenced by seasonal anoxia.
