Reliability Estimation for Vertical Lift Gate at Emsworth Dam
The lift gates are composed of two horizontal trusses, two vertical girders, seven diaphragms, and two end frames. A critical element in the structural integrity of the lift gate is a...

Economic Assessment of Infrastructural Development for the Gurara River in Nigeria
Based on the preliminary designs of the hydraulic structures for the proposed Gurara river water development project in Nigeria, an economic feasibility analysis is presented. The cost...

Wastewater Balance for Storage Pond at Land Treatment Site
Land application is an established method for treating municipal wastewater in the United States. Most land application operations include on-site facilities to store wastewater during...

Nonpoint Source Pollution Control & Land Use
Nonpoint source pollution control requires dealing with city, suburban and rural activities, and controlling pollution either at source, by detention basin quality control or by treatment...

Morris Sheppard Dam: A Rational Approach to Stability Analysis
This paper details the excessive foundation piezometric conditions found during a routine five-year inspection, and presents the results of backfigured stability analysis of a critical...

Benefit/Cost Analysis of Stormwater Detention Systems
In the past, detention basins have been designed to control peak discharge rates. However, there is considerable interest in using the detention basin for control of nonpoint source pollution....

Considerations for a Multiple-Use Stormwater Detention Facility
A 60-year-old neighborhood provides the unusual setting for the City of Tulsa's Turner Park-Will Rogers High School Stormwater Detention Facility. The 20-acre site is located...

Evaluation of Global Warming Impact on Soil Moisture and Water Runoff in Texas
In this paper a numerical evaluation of the variability of soil moisture and surface runoff due to global warming is carried out. An analytical model of the soil moisture balance based...

Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...

Contributions of Satellite Imagery to Water Resource Evaluations
Satellite images may also facilitate the development and maintenance of regional Geographic Information Systems (GIS) by providing both a source of base map creation and update, as well...

Comparison Between the Field and Laboratory Measured Properties of a Clay Liner
Hydraulic conductivity (K) and bulk density (BD) of an experimental clay linear were evaluated at a large number of locations using standard methods. They were then compared to laboratory...

Measuring Performance of Clay Containment Barriers
Clayey soils compacted to engineering specifications are widely used as structures for hydraulic containment. Current applications include landfill liners, landfill covers, pond liners,...

Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...

Non-Point Source Contamination of Aquifers
The paper discusses a new method for simulating the movement of contaminants from a diffuse source at the soil surface through a variably-saturated porous medium. The method accounts for...

Conductivity and Transit Time Estimates of a Soil Liner
A field-scale soil linear was built to assess the feasibilty of constructing a liner to meet the saturated hydraulic conductivity requirement of the U.S. EPA (i.e., less than 1 ? 10^-7...

Vaporizing VOCs
The authors summarize the findings of a study for the Environmental Protection Agency on vapor extraction of volatile organic compounds from soils. The potential for ground water contamination...

Remediating A Fire Site
Machin and Ehresmann describe remediation of a 15 acre fire site at Fort Huachuca, Ariz. An investigation after the fire showed that all of the debris contained asbestos. Sampling confirmed...

Oilcrete
Threatened by probable tightening of hazardous-waste legislation, oil companies are searching for ways to dispose of or stabilize oil-drilling byproducts. One way is cementitious stabilization...

Application of Interactive Videodisc for Work Zone Traffic Control Training
This paper describes the development of the Interactive Videodisc Training (IVT) system and a training course on work zone traffic control. The IVT system uses a microcomputer-controlled...

Tri-County Based Travel Demand Forecasting Analyses in the Tampa Bay Area, State of Florida
This paper describes the application of the micro-computer compatible Florida Standard Urban Transportation Modeling Structure (Micro-FSUTMS) to estimate traffic volume for the purpose...
