“…Field data itself must also be considered carefully since they, too, are limited representations of the prototype that are subject to error. Similar long-term data set comparisons can be found in studies detailed in references Berger et al (1995a) and Johnson et al (1993).…”

“…The hydrodynamic portion of the model solves the hydrostatic, free surface, Reynolds-averaged Navier-Stokes equations with turbulence closure, similar to the models of Blumberg and Mellor [26] and Johnson et al [27]. The numerical solution techniques are the same as those of Blumberg and Mellor [26], except for the solution of the free surface, which is implemented with a preconditioned conjugate gradient (direct) solver rather than an alternating-direction-implicit-method [12].…”

Abstract-Marine hydrokinetic (MHK) projects will extract energy from ocean currents and tides, thereby altering water velocities and currents in the site's waterway. These hydrodynamics changes can potentially affect the ecosystem, both near the MHK installation and in surrounding (i.e., far field) regions. In both marine and freshwater environments, devices will remove energy (momentum) from the system, potentially altering water quality and sediment dynamics. In estuaries, tidal ranges and residence times could change (either increasing or decreasing depending on system flow properties and where the effects are being measured). Effects will be proportional to the number and size of structures installed, with large MHK projects having the greatest potential effects and requiring the most in-depth analyses. This work implements modification to an existing flow, sediment dynamics, and water-quality code (SNL-EFDC) to qualify, quantify, and visualize the influence of MHK-device momentum/energy extraction at a representative site. New algorithms simulate changes to system fluid dynamics due to removal of momentum and reflect commensurate changes in turbulent kinetic energy and its dissipation rate. A generic model is developed to demonstrate corresponding changes to erosion, sediment dynamics, and water quality. Also, bed-slope effects on sediment erosion and bedload velocity are incorporated to better understand scour potential.

“…Water temperature and radionuclide concentrations also can be specified at those nodes. ALGE solves the set of 3-D partial differential hydrodynamic equations used by most researchers to predict the behavior of bodies of water with free surfaces (Blumberg and Mellor 1983;Oey et al 1985;Froehlich 1989;Jin and Kranenburg 1993;Johnson et al 1993). The equations used in ALGE are more fully developed in Garrett and Hayes (1997).…”

“…ALGE includes a free-surface simulator, first-order chemical reactions, and accounts for radioactive tracer transport/particle transport deposition and resuspension. The advective and diffusive terms in the 3-D hydrodynamic equation set for ALGE are solved by the conservative differencing scheme described by Roach (1972), Jin and Kranenburg (1993), and Johnson et al (1993).…”

Abstract3-D hydrodynamic models are used by the Savannah River National Laboratory (SRNL) to simulate the transport of thermal and radionuclide discharges in coastal estuary systems. Development of such models requires accurate bathymetry, coastline, and boundary condition data in conjunction with the ability to rapidly discretize model domains and interpolate the required geospatial data onto the domain. To facilitate rapid and accurate hydrodynamic model development, SRNL has developed a pre-and postprocessor application in a geospatial framework to automate the creation of models using existing data. This automated capability allows development of very detailed models to maximize exploitation of available surface water radionuclide sample data and thermal imagery.4
