Dynamic Analysis of Multi-Pool Irrigation Canal
This paper discusses the dynamic characteristics of an open multi-pool irrigation canal from robustness point of view. In particular, the presence of right-half plane zeros in an open...

Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...

Automatic Control of Flocculation Processes
A control system for flocculation, used in water and wastewater treatment operations is being developed. The approach is based on detailed particle size distribution measurements of influent...

Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...

A Method to Study Suspended Sediment Induced Flow Characteristics Changes
Sediment-laden turbulent flows occur in nature and through man-made hydraulic structures. Our current understanding of this two-phase flow phenomenon is incomplete, and many important...

Determination of Bridge Scour Velocity in an Estuary
Determination of the appropriate design for protection against bridge pier scour depends significantly upon the design velocities at the project site. In estuaries with large influences...

Modeling SSO's Resulting from Peak Conditions
Miami-Dade Water and Sewer Department (MDWASD) is undertaking the installation and maintenance of a computerized collection and transmission model and peak flow management study. Through...

Modeling Unsteady Open-Channel Flows Having Longitudinally Varied Fluid Density
Unsteady flows in waterways with fluid density varying longitudinally can be described by various sets of partial differential equations, according to conditions of density variation....

Eddy Pump Dredging Demonstration at Cresta Reservoir
A demonstration test of a new environmentally ifiendly slurry dredging technology using the EDDY Pump, a patented vortex slurry pump, was perfbrmed in 1994 at Cresta Reservoir in northern...

Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...

Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...

Temporal Development of Local Scour at Bridge Piers
The temporal development of local scour depth at circular cylindrical bridge piers is considered. New data are presented and used to quantify the influence of flow duration on the depth...

Evaluating Hydraulic Roughness in Tunnels
Much of the data presented in the literature on measured friction losses in tunnels are given in terms of the Darcy-Weisbach f or Manning's...

Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...

Physical Modeling to Determine Head Loss at Selected Surcharged Sewer Manholes
The head losses at sewer pipe junctions (manholes) under surcharged conditions were measured in a 1:6 scale model of a typical manhole with one main line passing through it and two perpendicular...

Assessment of Risks of Flooding by Use of a Two-Dimensional Model
In case of rare floods, the rivers might go far away from their minor bed, submerging large areas, eventually with relatively high velocities. One-dimensional models are not suitable to...

Engineering Mechanics
This proceedings contains keynote and summary papers presented at the 11th ASCE Engineering Mechanics Conference held in Fort Lauderdale, Florida, May 20-22, 1996. The keynote papers address...

Sound Way to Save Fish
Fish protection need not cost an arm and a fin. Using light and sound to spare fragile blueback herring and other species a harrowing fate, the U.S. Army Corps of Engineers devised a fish...

Engineering Mechanics
This proceedings, Engineering Mechanics: Proceedings of the 10th Conference, contains papers presented at the Conference held in Boulder, Colorado,...
