Delaware Estuary Nonpoint Source Control Program
Preparation of the Delaware Estuary Management Plan, sponsored by the EPA and the three states of New Jersey, Pennsylvania and Delaware, is part of the national estuaries program. As part...
Statistical Analysis of Wastewater Flow Reduction
Changes in urban water use patterns can significantly impact wastewater flow characteristics. With the increased emphasis on water conservation programs, understanding these impacts is...
Reservoir Water Quality Modeling in Northern Portugal?Some Case Studies
In the last two decades environmental problems have become a major concern in Portugal as the effects of water pollution have gradually impaired the quality of water resources. Mathematical...
Use of Contaminant Mobility and Transport Parameters to Determine Water Testing Protocol
By 1994, EPA plans to regulate 83 contaminants in public water supplies. For rural communities and individuals who are not classified as public systems, the cost to monitor all 83 contaminants...
Statewide NPS Management Strategies
Statewide nonpoint source (NPS) management strategies are necessary because there are several different levels of authority involved, and the priority of action needs to be related to...
A TVD MacCormack Method for Open Water Hydraulics and Transport
Water Quality and Hydrologic Characteristics of a Wet Detention Pond
A small wet detention pond was instrumented to determine treatment efficiencies. Annual loads showed a reduction from the inflow to the outflow for ammonia as nitrogen (39%), organic nitrogen...
The Potential Fate of Particulate Contaminants from the Rehabilitated Ranger Uranium Mine
In the initial period after rehabilitation of the Ranger Uranium Mine most particulate matter released into Magela Creek will be wash load. 10% of the annual deposits on the backwater...
Reuse Rules
Cities that discharge sewage effluent to surface water are under increasing pressure to reduce concentrations of heavy metals, ammonium and nitrate, and substances such as toxic organic...
Evaluation of Fine Aggregate Particle Shape and Texture
In an effort to minimize or eliminate permanent deformation (rutting) of heavy duty asphalt pavements most governing agencies now limit the amount of natural sand which generally (not...
Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...
Estuarine and Coastal Modeling
This is the proceedings of the second ASCE specialty conference on Estuarine and Coastal Modeling devoted to the rapidly evolving field of marine environmental modeling. The primary focus...

James L. Sherard Contributions
This volume is dedicated to the memory of Dr. James L. Sherard, who made many contributions to embankment dam engineering. Twenty-one of his papers related to this topic were selected...
Dual-System Cleanup
Engineers designing a ground water treatment system for a manufacturing plant in northern California, found that two systems are better�and cheaper�than one. Most of the ground water at...
Seismic Hazards in the Eastern U.S. and the Impact on Transportation Lifelines
In the eastern US seismicity is low, hazard is moderate, and risk is quite high, especially in metropolitan regions with vulnerable transportation systems typically not designed to resist...
Seismic Hazard Along a Central U.S. Oil Pipeline
An integrated approach is used to evaluate seismic hazards at six sites where pipeline 22 crosses the major rivers in West Tennessee. On the basis of historical and instrumental data,...
Seismic Hazard Analysis for Crude Oil Pipelines in the New Madrid Seismic Zone
The seismic vulnerability of three crude oil pipelines in and around the New Madrid Seismic Zone (NMSZ) is evaluated for a repetition of the 1811-12 New Madrid events. The seismic hazard...
Migration of Spilled Oil from Ruptured Underground Crude Oil Pipelines in the Memphis Area
This study evaluated the impact of an oil pipeline rupture in the recharge area of a West Tennessee aquifer. Two potential break locations were chosen in the alluvial valley of a main...
