Secondary-Flow Correction for Depth-Averaged Numerical Models
An empirical equation is proposed for the production and transport of secondary (streamwise) vorticity induced by lateral curvature in shallow water. The streamwise vorticity creates a...

Application of Weakly Compressible Flow Method to 2-D Open Channel Flows
The depth averaged equations for open channel flows are shown to be similar to that of the weakly compressible flows. The finite volume scheme developed for weakly compressible flows has...

Numerical Computation of Free Surface Weir Flow Using Isoparametric Finite Elements
Numerical computation of flows with a free surface boundary involves three problems in one: the internal flow problem, location of the free surface and the actual flow rate. The development...

Computation of Sediment Transport Resulting From Snowmelt and Rainfall in a Sierra Nevada Watershed
Erosion within a watershed can cause extensive damage to the land and adjacent properties. It is a common problem throughout the United States, and has become severe in many areas of the...

Redondo Beach King Harbor Model Studies, California
Redondo Beach King Harbor frequently experiences damage when large winter waves occur in conjunction with high water levels. Damages consist of revetment failure, land erosion, flooding,...
