Preparation of an Environmental Impact Statement (FERC, 1991) for licence applications for the Elwha and Glines Canyon hydroelectric projects on the Elwha River, Washington, included evaluation...
Sediment Modeling of Dam Removal Alternatives, Elwha River, Washington
The new version of the U.S. Army Corps of Engineers (ACOE) 1-Dimensional sediment transport model, HEC-6 'Scour and Deposition in Rivers and Reservoirs', was...
Sediment Problems Associated with Dam Removal, Muskegon River, Michigan
This paper presents an analysis of sediment movement in Michigan's Muskegon River following the removal of Newaygo Dam. The analysis utilized a physical process simulation...
Predicted Fluvial Response to Dam Removal in the Kalamazoo River Valley, Michigan
Research has been conducted by the Michigan Department of Natural Resources (MDNR) to predict the fluvial response to dam drawdown and determine the distribution of recent deposits along...
Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...
Enhancing Effluent Water Quality of Sedimentation Basins Using Constructed Wetlands Technology
The Tennessee Valley Authority (TVA) has constructed twelve wetlands to treat acid drainage at reclaimed coal mines and fossil-fueled power plants. These wetlands are designed primarily...
Large Woody Debris Effects on Channel Friction Factor
A simple method for quantifying large woody debris (LWD) density and computing associated friction factors was developed and tested using data from the South Fork Obion River in western...
Ultrasonic Velocity Meter Used in Stream Gaging
Many streams and canals in Florida are affected by tides or control structures and experience very low flow velocities at times. For example, the St. Johns River in northeastern Florida...
Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...
Model Studies of Outlet and Intake at McCook Reservoir
Two separate physical models were used to investigate the outflow and inflow into the proposed McCook Reservoir. The proposed reservoir will be located in McCook, Illinois, and will serve...
McClure Park: A Multi-Purpose Off-Stream Storage Facility for Tulsa, Oklahoma
The City of Tulsa is in the process of implementing a flood control plan for the 61 square-mile (158 km2) Mingo Creek watershed. The federally-assisted...
Sediment Sources Analysis for Peoria Lake Along the Illinois River
The modern-day lower Illinois River flows within a greatly oversized valley formed by an old course of the Mississippi River and glacial outwash events. As a result, the section of the...
Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...
Data Acquisition for Hydrologic GIS
Various data acquisition options for hydrologic oriented GIS are presented. These options include manual digitizing, commercial digital data, satellite products, and automated scanning....
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
Geographic Information Systems in Water Resources Management
The management of surface and ground water resources within Southern California is increasingly difficult. As population expands, municipal demands for water are increasing. At the same...
Turbulence and Reynolds Stress Distribution in a Natural River
Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway...
Verification of Clark County Hydrologic Modeling
