Environmental Degradation of Spawning Gravels in the Tucannon River
The important relationship between upstream soil and water conservation measures and salmonid habitat conditions in the Pacific Northwest is illustrated by way of computer simulations...
Channel Morphology and Habitat
Stream channels provide habitat for aquatic animals, such as fish and aquatic benthic invertebrates. Associated with the channel are near water habitats important to amphibians, reptiles,...
Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...
Kankakee Dam Discharge Characteristics
The low-head dam on the Kankakee River has flashboards which are installed as the discharge decreases in early summer, to maintain the upstream pool level. In response to concern over...
A Measure of Reservoir Efficiency
The notion of reservoir efficiency is defined for a water supply reservoir operated according to the standard policy, that is, one where the release is constant whenever physically possible....
Schoharie Creek Bridge Model Study
On April 5, 1987, a major storm occurred in the Schoharie Creek watershed and the resulting flood caused the bridge to fail. The hydraulic model of the bridge was performed to simulate...
The Life and Science of R. A. Bagnold
The purpose of this paper is to highlight and honor the exciting life and many significant contributions made by Brigadier Ralph A. Bagnold to our understanding of hydraulics and sediment...
Urban Drainage Calculation Limits for Small Areas
This paper discusses the selection and application of hydrologic techniques in the design of stormwater facilities, with particular emphasis on the selection of hydrologic procedure for...
U.S. Army Corps of Engineers Sedimentation Engineer Manual A. Overview
Until the 1970's, sediment analyses within the Corps of Engineers were mostly confined to estimates of the reservoir sediment storage needed, for the life of the project....
River Sedimentation
This paper discusses Chapter 4 of the U.S. Army Corps of Engineers Engineer Manual of Sedimentation Engineering. The chapter identifies potential river sedimentation problems, associates...
U.S. Army Corps of Engineers Sedimentation Engineering Manual D. Reservoir Sedimentation
This paper discusses Chapter 5, Reservoir Sedimentation, of the U.S. Army Corps of Engineers' Engineering Manual (EM) on Sedimentation Engineering, EM 1110-2-4000. The chapter...
Flow Field and Bed Topography in River Meanders
A mathematical model is developed for the calculation of flow field and bed topography in curved channels with an erodible bed. A small perturbation approach is used to linearize the governing...
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...
Friction Factor and Patterns in Armor Coats
Recent observations of friction factors at armor coat forming discharges suggest the presence of distinct geometric patterns in the locations of the coarsest grains in armor coats. A statistical...
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...
