Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...
Vessel Induced Physical Effects in a Navigation Channel
The U.S. Army Corps of Engineers is investigating ways to improve lockage efficiency at the Marmet Locks on the Kanawha River, West Virginia. A physical effects prediction model have been...
Prediction of Siltation at a Point
This paper describes a zero-dimensional mathematical model which predicts siltation at a point on a cohesive sediment bed. The processes of erosion, deposition and consolidation are modelled...
Channel Changes in the Platte River, 1926?1986
The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some...
Applicability of Several Common Methods of Debris Estimation
In southern California, the Tatum method and the Los Angeles County Flood Control District procedures have been widely used to estimation debris production rates. To evaluate the applicability...
Deposition at a New Dam Near Mount St. Helens
A sediment retention structure (SRS) is being constructed on the North Fork Toutle River in the state of Washington to trap sediments eroding off the 1980 Mount St. Helens debris avalanche....
International Research on Mechanics of River Bank Erosion?A Summary Overview
A brief overview is presented of research regarding mechanisms of river bank erosion and treatments. In the research river planforms, water stages, currents, waves, ice sediments, bed...
Sediment Evacuation System for Impounded Rivers
Current solution techniques for the reservoir sedimentation problem are presented and their rationale questioned. The need for focusing on the overall river transport regime is emphasized....
Some Pertinent Considerations in Dam and Reservoir Design
Two important considerations in designing and constructing a multipurpose earthdam and reservoir are to minimize losses in the event of dam failure because of overtopping, and to conserve...
How Many Years to Fill with Sediment, a Sediment Study of Lake Powell on the Colorado River
A study to determine the current capacity and to update information on the life expectancy of Lake Powell was conducted by the Bureau of Reclamation. The study documented the present storage-elevation...
Hydrometric Networks Serving Hydropower Needs
The Water Resources Branch is the national agency that collects, interprets and disseminates standardized surface water quantity and sediment data and information in Canada. The Branch...
Hydraulic Model Studies - Sidney A. Murray Jr., Hydroelectric Plant
The power plant is located at the Old River Control of the Lower Mississippi River (Louisiana). It consists of an intake channel about 5000 ft long, a power plant with eight bulb units...
Modeling Sedimentation Problems at Hydro Developments
Sedimentation embodies the processes of erosion, transportation and deposition of sediments. At hydro developments, sedimentation can create problems. Computer sedimentation models (CSM's)...
Quick Response on the Mississippi
In November 1987, the Mississippi River broke through the foundation of the St. Anthony Fall's Lower Dam Hydropower Plant. The plant's owner, the Northern State...
Storing Sediment and Freeing Fish
When Mount St. Helens erupted in May 1980, it sent a river of pyroclastic ash and other debris into Washington's North Fork Toutle River Valley. The resulting debris pile...
Preventive Maintenance: Fixing What Ain't Broke
Municipalities are often caught in the cycle of built-neglect-rebuild. For bridges, the solution is preventive maintenance: keep the bridges clean and painted, and they'll...
Hot Mix Asphalt Utilization in Railway Trackbeds
Described herein are the rationales for, descriptions of and evaluations of hot-mix asphalt (HMA) trackbed rehabilitation and construction techniques recently utilized in various classes...
Sediment Transport Modeling
This is the Proceedings of the International Symposium on Sediment Transport Modeling, held in New Orleans, Louisiana, August, 1989. It reviews the state of the art and presents the latest...
Fast Track, Instant Track
There is a newly constructed railroad bridge over the Wilamette River in Portland, Oregon. The 499 ft. clear maritime channel allows the world's largest ships to navigate...
The Race for Smart Cars
