White River Fish Screen Project Planning and Design
In 1983, Puget Sound Power and Light Company (Puget Power) submitted a license application to FERC for the overall White River Project. One of the elements of the project application was...

Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...

1995: Where the Past (Paleoflood Hydrology) Meets the Present, Understanding Maximum Flooding
Paleoflood hydrology has become accepted in the scientific, engineering, and regulatory communities and increasingly is being used to complement engineering hydrology throughout the Rocky...

Salinity and Hydraulic Issues at a Constructed Wetlands
A constructed wetlands at Boulder City, Nevada was designed to use effluent pumped from the City's wastewater treatment plant. The design was complicated by the highly permeable...

Infiltration Properties at Two Sites in the Konza Prairie
The spatial variability of soil hydraulic properties that govern infiltration were investigated at a pristine site and an agricultural site in the Konza Prairie Research Area of east-central...

Contraction Scour at Bridges Founded on Clay Soils
With the federally mandated bridge scour program deadline of January 1997 approaching, scour evaluations are in full progress in many states around the country. A common physical situation...

Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...

Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Q_s...

A Method to Study Suspended Sediment Induced Flow Characteristics Changes
Sediment-laden turbulent flows occur in nature and through man-made hydraulic structures. Our current understanding of this two-phase flow phenomenon is incomplete, and many important...

Overview of the US Army Corps of Engineers Flood Control Channels Research Program
The objective of the Flood Control Channels Research Program, currently being conducted at the US Army Engineer Waterways Experiment Station, is to develop design guidance and systematic...

Vegetative Roughness in Flood Control Channels
Laboratory flume tests and field evaluations were undertaken as a part of the Flood Control Channels Research Program to determine hydraulic roughness values for various types of floodplain...

Hydraulic Effects of Habitat Structures in Flood Control Channels
Three field sites have been established and laboratory flume experiments begun to assess the effect of habitat enhancement measures on water-surface profiles and local scour in flood control...

Using HEC-RAS to Compute Scour at Bridges
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...

Modeling the Lake Decatur Watershed in Illinois to Evaluate Effects of Best Management Practices on Nitrate Loading
The Illinois State Water Survey recently completed a two-year monitoring and modeling study of the Lake Decatur watershed in Illinois to develop land use management alternatives that would...

Managing Border Irrigation for Near-Zero Discharge
A dimensionless database of previously executed simulations of sloping-border irrigation with tailwater runoff constitutes the heart of design-aid software showing the effects on runoff...

On Conductivity of Soils with Preferential Flow Paths
Laboratory soil column experiments were conducted to study the distribution of preferential flow paths resulting from removal of colloidal size clay particles. These experiments specifically...

Sanitary Sewer System Modeling Model Comparison Racine, Wisconsin
As the use of computers continues to increase within the engineering profession, hydraulic computer models are used to simulate major interceptors and sometimes the entire sewer system....

Design of the Inlet/Outlet Tower for the Eastside Reservoir Project
The Eastside Reservoir is currently being constructed near Hemet, California, by the Metropolitan Water District of Southern California. When completed in 1999, water will enter and be...

Reduction of Downstream Impacts Through Use of Variable Detention Basin Volume Requirements
The Pre-post Match is the standard policy for regulating the design of detention basins for new developments despite evidence showing that as multiple developments occur in a watershed,...

Floodplain Analysis of the Lower Santa Margarita River in Camp Pendleton Marine Air Base, California
Floods of 1993 caused extensive flooding of the Santa Margarita River, and significant damage to Camp Pendleton. A floodplain analysis was performed including an assessment of recent flood...
