Animation Techniques for Visualizing Coastal Flow Dynamics
Numerical Simulation of Internal Kelvin Waves with Z-level and Sigma Level Models
Dynamic Optimal Groundwater Remediation by Granular Activated Carbon
Objective functions to describe the operating and capital costs of GAC treatment are incorporated into a control theory model for optimal pump-and-treat groundwater remediation design....
Pier Width and Local-Scour Depth
Presented here are the results of an enquiry into the effects of pier width on local scour depth. The results show that scour depth does not scale linearly with pier width unless there...
An LPI Numerical Implicit Solution for Unsteady Mixed-Flow Simulation
A Local Partial Inertia (LPI) technique is developed as an option within the National Weather Service (NWS) FLDWAV dynamic flood routing model to enhance its capability to model unsteady...
Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...
Feasibility of Modeling Phosphorus Dynamics in Stormwater Wetlands
This research, underway at the University of Guelphs School of Engineering, studies the feasibility of modeling phosphorus assimilative capacity by stormwater wetlands in cold climates....
Flood Forecasting Model for an Alpine Drainage Basin - River Drau in Austria
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...
Results of Field Evaluations of the New Modular Inclined Fish Diversion Screen
The Electric Power Research Institute (EPRI) has developed and biologically evaluated a new type of fish diversion screen known as the Modular Inclined Screen (MIS). The MIS is designed...
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...
Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...
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...
