Application of Particle Tracking Model for Ocean Outfall Siting in New Bedford, Massachusetts
PACE, a particle tracking model, was used to assist siting studies for an ocean outfall to be built in conjunction with the City of New Bedford's proposed new secondary wastewater...

High Early Strength Concrete Containing Large Quantities of Fly Ash
This paper presents results of research performed at a precast/prestressed concrete plant to identify optimum mix proportions for production of high early strength concrete with high fly...

Surface Plumes in Shallow Crossflow

Cold Weather Concreting in the St. Paul-Minneapolis Area

Modelling Estuarine Saltwater Intrusion

Pre-Treatment Process Control of a Variable Quality Raw Water Supply
The West Coast Regional Water Supply Authority is the public agency charged with the development of public water supply for the Tampa Bay Area in the state of Florida. The Authority's...

Self-Aerating Spillway Flow
The concept upon which most past analyses are based is that a continuum exists in aerated flow from 100 percent water, to air bubbles in water, to a water-air mixture, to an air-water...

Localized Mixing for Improvement of Hydropower Releases from J. Percy Priest Reservoir
The J. Percy Priest Project, located on the Stones River near Nashville, TN, experienced low dissolved oxygen (DO) in the tailwaters during hydropower generation. Using commercially available...

Wave—Current Interaction and Sediment Transport
The paper reports on a study into whether a close relationship between the mixing (diffusion) coefficient for the sediment, ɜs, and the mixing (diffusion)...

Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...

Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...

Lessons Learned in Laboratory and Field Evaluation of Accelerated Strength Tests for Quality Control of Concrete Pavements
This paper describes the results of an accelerated strength testing program performed to evaluate flexural strength potential at 28- and 90-days. Based upon a literature review of previous...

Chloride Diffusion Constant for Concretes
Reinforced concrete exposed to chloride ions rapidly deteriorates once the chloride concentration level exceeds the corrosion threshold limit. The diffusion of the chloride ion through...

CORMIX1: Expert System for Mixing Zone Analysis of Pollutant Discharges Into the Water Environment
The Cornell Mixing Zone Expert System (CORMIX) is an integrated software package for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses....

Freezing and Thawing Durability of High Strength Silica Fume Concrete
Specimens from 27 batches of concrete with a water to cementitious (cement plus silica fume) ratio of 0.25 to 0.32, with and without entrained air, were tested for freeze-thaw durability...

Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...

Flushing Flow Analysis Concepts
Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers....

Dynamic Behavior Characteristics of Thermal Discharge Plumes

Gas Transfer at Hydraulic Structures
Field measurements of gas transfer at hydraulic structures are notoriously difficult and imprecise. A technique which measures the transfer of hydrocarbon tracer gases has been tested...

Expert System for Mixing Zone Analysis of Aqueous Discharges (CORMIX1): Further Developments
Two recent publications have reported the development of the Cornell Mixing Zone Expert System (CORMIX) for the analysis, prediction and design of aqueous toxic or conventional pollutant...
