Current Measurements In The York River Near The Coleman Bridge, John M. Brubaker
Current Measurements In The York River Near The Coleman Bridge, John M. Brubaker
Reports
In support of Tidewater Construction Corporation's project to widen the George P. Coleman Bridge, current measurements were conducted in the York River between Gloucester Point and Yorktown, Virginia, along both sides of the bridge. The objective was to sample the currents at approximately 10 feet below the water surface during maximum ebb and flood flow, at enough locations to resolve cross-river variations in the flow field. This objective was well satisfied with multiple surveys conducted during ebb, slack, and flood phases of the tidal flow, each survey providing current data at multiple depths. Significant cross-river variability was documented.

Virginia Institute of Marine Science (VIMS) has been developing a general purpose three-dimensional hydrodynamic and sediment transport model, Environmental Fluid Dynamics Computer Code (EFDC; Hamrick 1992). The real-time model simulates density and topographically-induced circulation as well as tidal and wind-driven flows, and spatial and temporal distributions of salinity, temperature and sediment concentration. The model also is capable of handling the wetting and drying of shallow area, hydraulic control structures, vegetation resistance for wetlands and Lagrangian particle tracking. The information of physical transport processes, both advective and diffusive, simulated by the hydrodynamic model can be used to account for the transport …

Reports
The Virginia Institute of Marine Science, in cooperation with the Virginia Department of Conservation and Recreation, Division of Soil and Water conservation, has identified as one of its major goals the systematic study of hydrodynamic processes that affect recreational, shoreline and benthic resources in the coastal zone of the Commonwealth. As one component of the Virginia Coastal Information Program, a wave climatology project was initiated in 1988 with support from the National Oceanographic and Atmospheric Agency's Coastal Zone Management Program administered by the Virginia Council on the Environment. Directional wave observations were begun on a seasonal schedule (fall, winter, spring) …
