Simulation Modeling of Hydrodynamic Systems

Managing water use in riverine and estuarine systems requires an understanding of the governing supply, circulation, mixing, and flushing processes. Qualitative and quantitative evaluation of the hydrodynamic and transport properties of such water bodies can be computed via mathematical/numerical simulation models. To accurately simulate both the temporal and spatial variations of the flow, which significantly define the transport processes, the simulation model must be capable of accounting for hydraulic and tide-induced fluctuations, water withdrawals, discharges, winds, nonuniform geometric configurations, and other manmade or natural factors. Objectives of this project are to investigate and develop various mathematical/numerical techniques with which to simulate the hydrodynamics of one-, two-, and three space dimensional transient flows in various waterbodies; evaluate and/or develop methods to describe the transport of solutes in such waterbodies utilizing the comprehensive flow information derived from flow simulation models; and develop and implement an operational system in support of flow/transport simulation models.
