Three Dimensional Hydrodynamic Modeling Study, Craney Island Eastward Expansion, Lower James River And Elizabeth River, Virginia, Harry V. Wang, S. C. Kim, John D. Boon, A. Y. Kuo, G. M. Sisson, J. M. Brubaker, J. P-Y. Maa

Reports

The Craney Island Eastward Expansion Hydrodynamic Model Study was conducted in three phases: 1) model calibration and verification for the Elizabeth River, 2) model testing of four Craney Island expansion options using single variable runs (using a single variable, tidal range, for model input), 3) model testing of two expansion options using historical runs (using multiple variables in real time for model input). The expansion option designs were evaluated for both global and local hydrodynamic change through simulation comparisons with the Base Case condition.

Three Dimensional Hydrodynamic-Sedimentation Modeling Study : Hampton Roads Crossing, Lower James River, Virginia, John D. Boon, Harry V. Wang, S. C. Kim, Albert Y. Kuo, G. M. Sisson

Reports

A three-dimensional hydrodynamic-sedimentation computer model, HYSED-3D, was used to evaluate the effect of bridge-tunnel infrastructure for a proposed highway crossing of Hampton Roads on the physical characteristics (tides, currents, circulation, salinity, and sedimentation) of the James River estuary in Virginia. Model-represented infrastructure included tunnel islands and bridges on pilings connecting the islands to interstate highways in Newport News, Hampton, Norfolk, and Portsmouth, Virginia. Combinations of these elements occur in each of three proposed crossing routes designated Alternative 1 (Hampton-Norfolk), Alternative 2 (Hampton-Norfolk, Norfolk-Portsmouth), and Alternative 9 (Newport News-Portsmouth-Norfolk). Simulation comparisons were made between the existing waterways and infrastructure in Hampton …

A Three-Dimensional Environmental Fluid Dynamics Computer Code : Theoretical And Computational Aspects, John M. Hamrick

Reports

This report describes and documents the theoretical and computational aspects of a three-dimensional computer code for environmental fluid flows. The code solves the three-dimensional primitive variable v1ertically hydrostatic equations of motion for turbulent flow in a coordinate system which is curvilinear and orthogonal in the horizontal plane and stretched to follow bottom topography and free surface displacement in the vertical direction which is aligned with the gravitational vector. A second moment turbulence closure scheme relates turbulent viscosity and diffusivity to the turbulence intensity and a turbulence length scale. Transport equations for the turbulence intensity and length scale as well as …

Beach Erosion And Accretion At Virginia Beach, Victor Goldsmith, Susan C. Strum, George R. Thomas, Coastal Engineering Research Center (U. S. )

Reports

This report is published to provide coastal engineers with a description of beach erosion and accretion at Virginia Beach, Virginia, including the effect of continuing beach replenishment, and the apparent unimportance of land use in determining erosion. This report also provides bench-mark data on coastal processes at the shore north of the CERC Field Research Facility at Duck, North Carolina. The work was carried out under the beach evaluation program of the U.S. Army Coastal Engineering Research Center (CERC).
