Natural Progression
Engineers made storm-water detention, wetlands mitigation, and environmental safeguarding part and parcel of an industrial expansion project. Designers have created an inviting front yard...

Application of a SonTek Argonaut Side-Looking (SL) Doppler Flow Meter for Measuring Discharge on the Southern Leg of the Parana' River at the Entrance to the Itaipu Binacional Reservoir, Parana', Brasil
Index-velocity and water level data collected with a SonTek Argonaut Side-Looking (SL) Doppler Flow Meter and channel cross-sectional area data were used to compute total discharge on...

Establishing Baselines For Pipeline Condition Master Planning
As our most of our cities approach complete built-out and much of our wastewater pipelines near the end of their design life, attention needs to be focused on retiring deteriorated first...

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...

Quality Control Test for Prestressing Wires in Concrete Pressure Pipe
Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts...

Non-Destructive Excavating Around Pipelines and Challenging Conditions
Hydrovac technology provides engineers and contractors with a unique solution for non-destructive excavating around sensitive buried lines. As a non-mechanical excavating method, it is...

Economic Restoration of Concrete Infrastructure at Jefferson Parish, Louisiana
United States municipalities are spending hundreds of millions of dollars annually tore place and repair corroded concrete infrastructures in wastewater systems. Structures such as wet...

Use of New Liner In Water Distribution System
For years there has been interest in rehabilitation of water distribution systems to provide quality drinking water and to reduce breaks in the water system service. Much work has been...

A Major Water Main Crossing of the Ohio River at Cincinnati
This presentation chronicles a major water main crossing of the Ohio River at Cincinnati. The project is of interest because it provides for the interstate sale of drinking water and technical...

Turbulence, Bottom Boundary Conditions, and Sediment Transport in a Shallow Water Habitat
Field experiments were designed to explore the effects of vegetation on the hydrodynamics and sediment transport in Franks Tract, a shallow water habitat in the Sacramento-San Joaquin...

Sediment and Nutrient Monitoring and Modeling in Lake Tahoe Basin, California, U.S.A.
The water quality of Trout Creek, South Lake Tahoe, California is monitored to assess the system's response to stream restoration. It is the principal endeavor to conduct a systematic...

Calibration of Water-Velocity Meters
The U.S. Geological Survey (USGS), as part of its responsibility to appraise the quantity of water resources in the United States, maintains facilities for the calibration of water-velocity...

The Determination of Velocity Spectra and Dissipation by Direct and Indirect Means using Second-Order Accurate PIV
In this paper we present a 2 nd order accurate technique in space (following Wereley & Meinhart's (2001) extension of Cowen & Monismith's (1997) dynamic sub-window PIV...

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...

Penn State's Graduate Option in Watershed Stewardship
A Graduate Option in Watershed Stewardship has been created at Penn State with the objective of educating water resources students to implement team-oriented, interdisciplinary problem...

Watershed Management Education at The University of Arizona
Watershed management education at the University of Arizona is described and discussed in the perspective of other educational programs, and national and international activity. The Watershed...

Watersheds: Preparing Students for the Future
Colorado State University continues to maintain the only undergraduate major in Watershed Science since its inception over four decades ago. As the flagship of Watershed Science, CSU has...

Water Quality Restoration of the Mammoth Cave Karst Aquifer: A Work in Progress
Over tens of thousands of years the aquatic ecosystem of the Mammoth Cave Karst Aquifer evolved in concordance with natural recharge supplied through 24,000 hectares of tall-grass prairie...

Effects of Wildfire on Water Supplies: A Case Study from Denver, Colorado
Wildfires can directly impact municipal water supplies by increasing a watersheds susceptibility to erosion, and thereby potentially increasing the transport of sediment and organic matter...

Erosion from an Industrial Forest Road in the Ouachita Mountains of Southeastern Oklahoma
Erosion from 4 segments of a 2-year old forest road in a 740 ha basin was measured for each of 105 storms that occurred in a 3.5 year period. Two road segments were part of a mid-slope...
