Changing Channels
When the strict design parameters of a correctional facility in remote Pennsylvania meant blocking a headwater stream, a team of environmental engineers rerouted the waterway 400 ft (122...

Larger Foraminifers as Contributors to Carbonate Beach Sands
Larger foraminifers are locally significant contributors to tropical carbonate sediments, particularly in the Indo-Pacific region. The two major factors influencing foraminiferal production...

Geotechnical Aspects of Beach Restoration
Large-scale beach restoration undertaken by the U.S. Army Corps of Engineers in Florida requires millions of cubic yards of beach quality sand. Exploration for these sand resources starts...

Carolina Crossing
The designers of a cable-stayed bridge across the Cooper River in South Carolina incorporated stringent seismic criteria to safeguard against potentially devasting earthquakes....

Uses and Limitations of Conventional Hydraulic Models in the Planning and Design of Storage Tunnels
The hydraulic design of storage tunnels requires special considerations relative to the design of conventional sewers. These issues include characterization and control of inflows, energy...

An Aggressive I/I Abatement Program is Underway as Part of Vallejos Wet Weather Program
The Vallejo Sanitation and Flood Control District (VSFCD) is undertaking an aggressive pilot program to control wet weather flows and eliminate sanitary sewer overflows (SSOs) that are...

Buffalo Cove Water Management Unit, Atchafalaya Basin, LA: A Case Study
The Atchafalaya Basin is a system undergoing change in topography and subsequently, hydraulics and hydrology. The U.S. Army Corps of Engineers funded and constructed an initial small-scale...

The Watershed Modeling System
The Watershed Modeling System (WMS) is a comprehensive environment for hydrologic analysis developed by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University...

Using Tracer Response Curves to Quantify Hydraulic and Channel Complexity of Prairie Creek, Northwestern California: Implications for Over Wintering Habitat for Juvenile Coho Salmon
This study measured and compared aspects of channel structural complexity with hydraulic complexity at a range of flows including winter storm flows. Five 200-meter reaches containing...

Design Considerations for the North Railroad Alluvial Fan Levee System in Boulder City, Nevada
This paper presents a drainage study for a flood control levee system in Boulder City, Nevada. This levee system is located below an alluvial fan watershed and was proposed to protect...

Pushing Back
(Available on in special edition) The design for the $3.5-million Cameron Run tunnel rehabilitation project involved a tricky and relatively unproven method of pushing corrugated steel...

A GIS Model for Assessing the Impact of Increased Channel Discharges on Hydraulic Geometry
A GIS model is being developed that can be used to assess the impact of increased channel discharges on the hydraulic geometry of streams in the Powder River (structural) Basin in northeast...

Return of the Master Builder
As projects become more complex and clients demand streamlined design and construction approaches, more consulting companies are attempting to add hard-dollar construction to their scope....

Sealing Springfield
The city of Springfield, Missouri, initiated a $12-million, 12-year infiltration and inflow elimination program for its sanitary sewer system after a federal lawsuit was filed to seek...
