A Hydrodynamic Model of Mobile Bay, Alabama
نویسندگان
چکیده
This paper presents a hydrodynamic model of Mobile Bay developed using the Adaptive Hydraulic Modeling system (ADH), the Hydrological Simulation Program FORTRAN (HSPF), and the Mesh Generation and Refinement Tool (MGRT), to simulate water surface elevations in Mobile Bay, Alabama. The computational grid was created using MGRT and NOAA’s coastline and bathymetric data. HSPF provided stream flow time series for establishing fresh water boundary conditions. NOAA’s tidal stations in the region were used for establishing ocean boundary conditions and for calibrating the model. ADH was used for the actual hydrodynamic calculations. The existing parallel ADH code (developed at USACE-ERDC) was compiled in a 384-node computer cluster and an exploration of the optimum number of processors for the model’s runs was performed. With the parallelized code, speed-ups of up to 21 were obtained. The hydrodynamic calibration of the Mobile Bay hydrodynamic model was greatly eased with the parallelized ADH version. The Surface Water Modeling System (SMS) was used for partial preprocessing (add bathymetry data to mesh) and visualization of the results. Calculated and observed water depths were consistent (r2 > 0.75).

This paper presents a comparison of two hydrodynamic models of the Weeks Bay sub-estuary (Alabama, USA). One model was developed using the Environmental Fluid Dynamic Code (EFDC). The resulting model was compared to an existing hydrodynamic model (of the same water body) that was developed using the Adaptive Hydraulic modeling system (ADH). Comparisons were performed in terms of predicted water...

This paper presents a methodology for using hydrodynamic modeling to estimate inundation areas and water depths during a hurricane event. The Environmental Fluid Dynamic Code (EFDC) is used in this research. EFDC is one of the most commonly applied models to Gulf of Mexico estuaries. The event with which the hydrodynamic model was tested was hurricane Ivan. This hurricane made landfall at the A...

Bushehr Bay is situated along the northern Iranian coasts of the Persian Gulf, between 28°52΄ and 29°5΄ north latitude and 50°42΄ and 50°52΄east longitude. In this study COHERENS, which is a threedimensional hydrodynamic model, was employed to simulate surface and under surface currents in the Bushehr Bay. The atmospheric forces and four main tidal constituents M2, S2, K1, O1 and also boundary ...
