Processes of Meander Bend Migration
The flow pattern in a meander bend is described in terms of the primary flow, secondary flow, and cross-stream flow. Secondary flow which is normal to the primary flow contributes to lateral...

Flood Event Prediction with Movable Bed Model
This study shows the applicability of using a numerical sedimentation model to analyze various problems related to flood-control design in an alluvial river. Problems concerned with maintaining...

Predicting Channel Recovery from Sand and Gravel Extraction in the Naugatuck River and Adjacent Floodplain
Gravel extraction at five sites along the Naugatuck River in Connecticut is of sufficient magnitude that channel recovery to pre-mining morphology is expected to require up to several...

Prediction of Scour Depth Under Armoring Conditions
A simple procedure is proposed to compute scour depth on an alluvial bed having graded materials under flow conditions which produce armor layer at the bed surface. The procedure is based...

Twenty Years of Experience in Unsteady Flow Modeling of Open Channels at TVA
Two concerns prompted the development of dynamic methods for flow routings: (a) the safety of the nuclear plants being planned along the Tennessee River in the 1960's and...

A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...

Physical River Model Results and Prototype Response
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has performed physical hydraulic model studies on various rivers for nearly 60 years. These studies...

Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...

Performance Evaluation of Channels Stabilized with ARS-Type Low-Drop Structures
Field and hydraulic investigations of seven ARS-type low-drop grade-control structures located in Mississippi indicate that most of the structures become submerged during flows with recurrence...

Measurement and Analysis of Tracfcfifc-Induced Transient Motion in Navigation Channels
Two-induced physical effects related to navigation changes on the Kanawha River, West Virginia were measured at three environmentally sensitive representative locations. The purpose of...

Unsteady Flow in a Navigation Channel
Based on the de St Venant equations, the Preissmann's implicit finite difference scheme, and the double sweep algorithm, a mathematical model for one-dimensional unsteady...

Discharge Measurement by Thermal Dilution
A flume study was conducted to develop and improve the thermal dilution method of discharge measurement in trapezodial channels. The study was performed in an indoor channel with dischages...

Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....

Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...

Hydraulic Engineering
The papers in this book were presented at the National Conference on Hydraulic Engineering, August, 1988, Colorado Springs, Colorado. The objective of this conference was to provide a...

Granite Reef Underground Storage and Recovery Project
The Granite Reef Underground Storage and Recovery Project facility is an integral part of the largest water management system under development for the Phoenix metropolitan area. The project...

Conjunctive Use in the Niles Cone, California
The use of in-stream facilities for artificial recharge in stream channels as practiced in Alameda County, California, is discussed. The facilities are (1) stream channels with no other...

Artificial Recharge of Ground Water via Paddy Fields in an Alluvial Fan, Northern Japan
Artificial ground water recharge via paddy fields was tested during the winters of 1985/86 and 1986/87 in order to protect declining water levels. The purpose of this paper is to discuss...

Environmental Impacts of Arctic Marine Transportation: Addressing the Issues through Research and the Provision of Advice
The prospect of numerous transits of the Canadian Northwest Passage and other northern waters by icebreaking tankers raises various environmental issues. This paper reviews the growth...

Environmental Considerations to Channel Dredging
In this paper two principal areas of environmental concern were investigated. The first is the physical impact of dredging and deposition of solid materials causing turbidity on aquatic...
