Initial Investigation of Multidimensional Flow and Transverse Mixing Characteristics of the Ohio River near Cincinnati, Ohio

摘要

This report documents an initial investigation of flow and mixing characteristics along a 34-mile reach of the Ohio River from a water-level gaging station at Cincinnati, Ohio, upstream to the Meldahl Dam. Acoustic Doppler current profiler (ADCP) surveys and ancillary data provided flow, velocity, flow-depth, and water-level information needed to estimate channel roughness and eddy-viscosity parameters associated with a two-dimensional (2D) hydrodynamic model, and two dye-injection studies provided concentration data needed to estimate turbulent mixing and dye-decay parameters in a 2D water-quality transport model. Boundary conditions for model simulations included water-level data from the USGS gaging station at Cincinnati, Ohio, and available flow information at Meldahl Dam.
