Three-dimensional hydrodynamic model set-up: a case study of middle Tennessee River
… Fluid Dynamics Code (EFDC) is a widely used hydrodynamics model that is no longer up to date with modern technology. As part of this research, an automated MATLAB based structured grid generator for EFDC was developed and was tested by developing a test model for Tennessee River near …

Implementation of a one-dimensional hydrodynamic model for the Middle Paraguay River Basin
A steady 1D hydraulic model (HEC-RAS) was implemented for the Middle Paraguay River Basin (MPRB), which comprises a reach between Porto Murtinho, Brazil, and Asunción, Paraguay. In order to prepare the model, first the topo-bathymetry was prepared by digitizing more than 10,000 depth points from …

Comparison of the 1D idealised flux theory and a 2D hydrodynamic model with full scale secondary settling tank performance data
In this research, the two dimensional (2D) hydrodynamic model SettlerCAD (Zhou et al., 1998) was applied to full-scale circular secondary settling tanks (SSTs) with the principal aim to 1) establish whether or not it "automatically" reproduces a flux rating <1.0 with respect to the steady state 1D …

Modeling of nearshore hydrodynamics for sediment transport calculations
… analyzes and improves Tajima's (2004) nearshore hydrodynamic model. Tajima's simple model accurately predicts long-shore sediment transport along long, straight beaches, while cross-shore transport predictions differ from observations. A better prediction of cross-shore transport requires …

Hydrodynamic modelling of the oscillating wave surge converter
This thesis investigates the numerical modelling of the Oscillating Wave Surge Converter (OWSC). The OWSC is a bottom hinged, flap-type, pitching wave energy converter. The device is installed in shallow water (10 - 15 metres} and covers the entire water column from the sea floor to the water …

Hydrodynamics and freshwater diversion within Barataria Basin
… developed two-dimensional, depth-integrated hydrodynamic model is applied to simulate estuarine processes. The equations for conservation of mass and momentum predict specific physical processes when forced by tidal and salinity variations at the open boundaries, wind forcing patterns, …

MEASUREMENT AND MODELLING OF ESTUARINE CHEMISTRY
A l-D tidally resolving hydrodynamic model of the Tweed Estuary has been encoded using the Estuarine Contaminant Simulator, ECoS. The model results of axial and time series variations in water elevation, salinity and turbidity are compared to field data recorded during the LOIS survey programme. …

An Implicit Finite-Volume Depth-Integrated Model For Coastal Hydrodynamics And Multiple-Sized Sediment Transport
A two-dimensional depth-integrated model is developed for simulating wave-averaged hydrodynamics and nonuniform sediment transport and morphology change in coastal waters. The hydrodynamic model includes advection, wave-enhanced turbulent mixing and bottom friction; wave-induced volume flux; wind, …

Three-Dimensional Numerical Modeling Of Multiple-Sized Sediment Transport Modeling Under Current And Waves
In this study, a three-dimensional numerical model of multiple-sized sediment transport under current and waves is developed. The coastal circulations are described by a three-dimensional hydrodynamic model, which is governed by the three-dimensional phase-averaged shallow water flow equations …

Evaluating the combined use of three-dimensional hydrodynamic modeling and polyethylene passive sampling in the Lower Duwamish Waterway
… can be coupled with a three dimensional (3D) hydrodynamic model of a given surface water body to identify where sources contributing to the measured concentration distribution are most likely located and what mass flux is required to produce the measured concentrations. This evaluation was …
