Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...
Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...
Flow and Chloride Transport in the Tidal Hudson River, NY
A one-dimensional dynamic-flow model and a one-dimensional solute-transport model were used to evaluate the effects of hypothetical public-supply water withdrawals on saltwater intrusion...
Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...
Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...
Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...
Deicing Denver
Glycol-based deicing fluids are an essential part of winter operations at most airports. While these chemicals help ensure safe and timely aircraft operations, stormwater runoff contaminated...
Building A Barrier Wall Through Boulders
Engineers and contractors conceived a novel approach to a barrier wall at a difficult site near the Niagara River in New York State. The site had been contaminated by a chemical company...
The Variability of Large Alluvial Rivers
Written by river engineers and earth scientists who are experts in river morphology, dynamics, and control,
Spoils of War
Watertown Arsenal, a former U.S. Army arsenal and nuclear research site noted for its innovations in armament technology, has been shut down and is destined to be returned to civilian...
Fishy Business
Hydroelectric power accounts for about 12% of U.S. electric supply and virtually all the nation's renewable energy capacity. Yet hydro is under increasing attack on environmental...

Automation of Design at the New Denver Airport
This paper outlines an innovative approach to automating the roadway design process by linking design and drafting with multiple software programs and taking advantage of the strengths...
Grading Design Using CADD: Denver International Airport Roadways
Using the terminal access roadway site for the new Denver International Airport as an example, this paper outlines a method for automating the preparation of grading plans and computation...
Steel Alternates for the Hoover Dam Bridge
As input to the Environmental Impact Statement studies of appropriate long span bridges were performed for three alternate corridors across the Colorado River near Hoover Dam. Details...
Rehabilitation of the Deep Creek Lake Dam
This paper presents the rehabilitation design for upgrading the Deep Creek Lake dam. The Deep Creek dam is a rock fill dam, 92 feet (28 m) high and 1290 feet (393 m) long, and constructed...
The Long Term Interim Storage of Spent AGR Fuel
This paper describes the work undertaken by Scottish Nuclear Ltd. on the proposal to construct a naturally cooled dry store for spent advanced gas cooled reactor fuel at Tornes Power Station,...
Resource Implications of Listing Columbia River Basin Salmon Stocks Under the Endangered Species Act
The Columbia River and Snake River dams and reservoirs provide substantial benefits in the Northwest through their operation for hydropower, flood control, irrigation, navigation, and...
