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,...

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...
Under Cover
The impermeable properties of flexible membrane liners have made them hot properties for landfill closure-cover systems. But slip-resistant clay might still be the best cover material...
Calendar: Bridges 1995
Featured bridges are: Lacey V. Murrow Floating Bridge (WA); Waco Suspension Bridge (TX); Rexleigh Bridge (NY); Hernando Bridge (AK & YN); Third Street Bridge (PA); Klamath River...
Wind Design and Analysis for the Normandy Bridge
The Normandy Bridge will represent an important progress in the field of cable-stayed bridges, with a main span 856-metre long. This paper explains how the design has been oriented to...
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...
Effects of Earthquake Intensities and Site Conditions on the Reliability of RC Frame Structures
This paper evaluates the effects of seismic zone factors and site coefficients on the seismic reliability of reinforced concrete frame structures. A nine-story intermediate moment-resisting...
Reliability Analysis of Navigation Structures
Methods for probabilistic stability analyses of concrete monoliths at hydraulic structures were developed and tested. Numerous analyses were performed using data from six actual structures...
Improving Seismic Safety of Dams in California
A search of the dam files at California's Division of Safety of Dams has revealed that at least 94 dams have been improved for seismic stability. The results of the search are tabulated...
Remedial Design and Construction to Improve a Sliding Embankment
The paper describes the studies made to identify the nature of possible remedial measures such as improved drainage, removal of the weak clay layer or a provision of a buttressed dam....
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
Using Innovative Technologies and Geosynthetics in Embankment Dam Rehabilitations
The ever increasing development and confidence in new and innovative technologies such as geosynthetics, in conjunction with often significant economic advantages, have led designers to...
