Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...
Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...
Comparison of Worst-Case and Probabilistic Approaches to Ocean Outfall Mixing Zone Analysis
Two approaches have been used for ocean outfall mixing zone analysis: worst-case approach and probabilistic approach. This paper discusses some advantages and disadvantages of the worst-case...
Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...
A Three Dimensional Oil Spill Model
This paper reports the development and testing of a comprehensive three-dimensional oil spill model. At present time, the model components include advection and turbulent diffusion, vertical...

Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...
Scour Protection in Bottomless Culverts
This paper will describe the relative severity of scour anticipated to occur at bottomless culverts and will provide some design guidance for scour protection based on research referenced...
Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...
Integrated Facility Information Systems: Total Information Access
This paper will attempt to fill the void in computer information handling with regards to facility management information by providing those in the water industry with tips and suggestions...
Restoration Design for Urban Streams: Anacostia River Basin, Maryland
Several stream restoration projects have been undertaken by the Army Corps of Engineers in the Maryland portion of the Anacostia River basin. Measures used include bank stabilization,...
An Engineering Information System Application for Water Supply and Distribution Systems
Engineering information systems are characterized by both static infrastructure and dynamic time dependent data. Telemetered readings can often be relatively substantial over an extended...
Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...

Rock Foundations
This manual provides technical criteria and guidance for the design of rock foundations for civil works or other similar large military structures. It provides a minimal standard to be...
Tensioned Fabric Structures
A Practical Introduction
The objective of this publication is to provide basic information about the nature and characteristics of tensioned fabric structures. Its target audience includes architects, engineers,...
Big Business
Prior to the 1990s, there were few mergers in the environmental engineering consulting industry. Growth and profitability were generally sufficient to compensate owners and employees and...
Retail Renovations (Available only in
