A Surface Collection Design Approach on the Lower Columbia River
Surface collection and bypass of downstream migrating juvenile salmon has the potential to help improve the survival of the Columbia River salmon population. However, surface passage on...

Surface Bypass-Collector Concepts and Performance
Surfacetype bypass collectors and concepts are described. Biological and engineering requirements to pass juvenile salmonids at Snake?Columbia River dams are presented. The components,...

South Carolina Department of Transportation's Statewide Program of Bridge Scour Evaluation
The South Carolina Department of Transportation (SCDOT) has instituted a program to satisfy the FHWAs requirements to evaluate the scour potential of the Nations bridges. The SCDOT's...

Dynamic Analysis of Multi-Pool Irrigation Canal
This paper discusses the dynamic characteristics of an open multi-pool irrigation canal from robustness point of view. In particular, the presence of right-half plane zeros in an open...

System Downstream Control for On-Demand Irrigation Canals
A nonlinear programming (NLP) Model has been developed to assist downstream control for optimal control of canal systems, called system downstream control (SDC). The objective of system...

Successful Implementation of Grouted Boulder Grade Control Structures on Drainageways in the Denver Metropolitan Area
This paper describes the development of design guidelines for the Grouted Sloping Boulder drop structure as an alternative for the sloping riprap drop structure. A number of partial failures...

Groundwater Remediation Design When Pretty Good is Good Enough
This paper introduces some new approaches toward the optimal design of groundwater remediation systems or any other engineered systems. These new approaches primarily consist of making...

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...

Analysis of Exceptional Meteorological Conditions on July and August in Conakry
Conakry is a zone that receives more precipitation than other countries in West Africa. Sometimes the quantity is more than 4,000 mm per year. Strong rainfalls are observed between July...

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...

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...
