Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...
Sediment Yield and Accumulation in the Cache River
Sediment data collected in the Cache River basin of southern Illinois were used to calculate the sediment yield from tributary streams draining into a significant wetland area. Sediment...
Flow Separation Around a Solitary Dike: Eddy Viscosity and Mesh Considerations
The hydronamic model RMA-2V has been verified on a variety of global circulation studies. These studies rarely involved separated flow patterns around sudden expansions or contractions....

Hydraulic Modeling of Flow Control Gates
Flow control gates are subject to complex hydrodymanic loadings, which may in many cases only be predicted through investigation on a physical hydraulic model. Scaling of gate models,...
Three-Dimensional Modelling of Recirculation Behind a Groyne
Extensive investigation on the three-dimensional flow patterns behind a groyne have been carried out in a small-scale experiment. A three-dimensional hydrodynamic numerical model is verified...
Validation and Recent Enhancement of a Three-Dimensional Curvilinear-Grid Finite-Difference Model for Estuarine, Coastal and Lake Circulation: CH3D
This paper describes the validation and recent enchancement of a three-dimensional curvilinear-grid hydrodynamic model: CH3D. The model employs finite-differences techniques and allows...
River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...
