Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...

The Turbulent Wake of a Recirculating Eddy in Shallow Waters
The wake, created by injecting dye into the recirculating zone of a sudden lateral expansion in a shallow open channel, is examined experimentally for a range of bed-friction influence....

Cellular Automaton Simulation of Viscous Free Surface Fluid Dynamics
It has been demonstrated elsewhere that the simple interaction of a two dimensional field of discrete particles traveling on a regular lattice yields large scale behavior closely approximating...

Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....

Cocohatchee River Basin Study
The report presents the modeling of the Cocohatchee River basin, including 2-D routings for wetland regimes, hydrologic/hydraulic analyses of the agricultural and suburban land uses, and...

Resilient Moduli of Soils
