Mobile Bay Scour Analysis for Mobile and Baldwin Counties, Alabama
Scour analyses were prepared for ten bridges and causeways in and around Mobile Bay on the Gulf Coast of Alabama. Interactions between riverine floods on the Mobile River and tidal storm...

South Carolina Department of Transportation's Statewide Program of Bridge Scour Evaluation
The South Carolina Department of Transportation (SCDOT) has instituted a program to satisfy the FHWAs requirements to evaluate the scour potential of the Nations bridges. The SCDOT's...

Modeling Groundwater Response to a Perimeter Flood
A large industrial facility in the west of France was impacted by a flood in January 1995. Costs associated with the disruption in one week of production were estimated at $15E6 US. In...

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...

System Downstream Control for On-Demand Irrigation Canals
A nonlinear programming (NLP) Model has been developed to assist downstream control for optimal control of canal systems, called system downstream control (SDC). The objective of system...

Successful Implementation of Grouted Boulder Grade Control Structures on Drainageways in the Denver Metropolitan Area
This paper describes the development of design guidelines for the Grouted Sloping Boulder drop structure as an alternative for the sloping riprap drop structure. A number of partial failures...

Groundwater Remediation Design When Pretty Good is Good Enough
This paper introduces some new approaches toward the optimal design of groundwater remediation systems or any other engineered systems. These new approaches primarily consist of making...

Investigating the Non-Convexity of the Groundwater Quality Management Response Function
Under certain simplifying assumptions, the groundwater quality management model can be considered a function of a limited number of variables that describe both the transport simulation...

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...

Hydrodynamic Simulations in Sediment-Carried Contaminant Modeling for the Buffalo River, New York
Accurate prediction of hydrodynamics is of great importance to modeling contaminant transport and water quality in a river and to estimating potential exposure contamination levels in...

Upper Chehalis River Pollutant Capacity and Load Allocations
Dry season water quality was evaluated in the Upper Chehalis River in western Washington state, focusing on low dissolved oxygen (DO), and using the Total Maximum Daily Load (TMDL) process....

Game Model Approach to Multi-Purpose/Multi-Objective Water Resources Related Environmental Protection Project Planning and Management in Developing Nations: A Nigerian Example
The best has not been realised from water resources related environmental protection projects in Nigeria due to problems militating against such projects at the planning, management and...

Analyzing Drought with a Simplified Climate Model
A simplified climate model with combined atmospheric-hydrologic processes has been developed at the University of California Davis for the study of physical processes related to drought....

Development of a Regional Atmospheric-Hydrologic Model for the Study of Climate Change in California
An integrated model of atmospheric and hydrologic processes at regional scale over California has been developed in order to translate the large scale atmospheric conditions of critical...

Mapping Groundwater Vulnerability to Nitrate and Pesticide Contamination in the Salinas Valley, Monterey County, California
This paper describes the approach and the associated investigation leading to the development of groundwater vulnerability maps for a critical water supply region in the Monterey County....

Flow through Vertical Barrier Screens?Numerical Model
A simple one-dimensional numerical model based on the energy equation is developed to predict the normal flow distribution through barrier screens composed of several vertical segments...

White River Fish Screen Project Planning and Design
In 1983, Puget Sound Power and Light Company (Puget Power) submitted a license application to FERC for the overall White River Project. One of the elements of the project application was...

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...

1995: Where the Past (Paleoflood Hydrology) Meets the Present, Understanding Maximum Flooding
Paleoflood hydrology has become accepted in the scientific, engineering, and regulatory communities and increasingly is being used to complement engineering hydrology throughout the Rocky...

Salinity and Hydraulic Issues at a Constructed Wetlands
A constructed wetlands at Boulder City, Nevada was designed to use effluent pumped from the City's wastewater treatment plant. The design was complicated by the highly permeable...
