Progress in Hydromechanics
The historical development of hydromechanics in the fifty years since the founding of the Hydraulics Division is reviewed. Rouse's 1938 text, Fluid Mechanics for Hydraulic Engineers, provided...

Surface Water Hydrology
A brief history is presented of activities in surface water hydrology by the Hydraulics Division since 1938. Included is an historical review of division activities in such areas as precipitation...

Research in ASCE's Hydraulics Division
Research in the Hydraulics Division of ASCE during the last 50 years has undergone changes in both technical content and procedures. Open channel flow, sediment transport and pipe flow...

Cold Regions Hydrology and Hydraulics
The Cold Regions Hydrology and Hydraulics Monograph is the eighth in a series of monographs prepared by the ASCE Technical Council on Cold Regions Engineering. The book is intended to...

Water Jets Fight Silt
In the largest U.S. application to date, an array of hydraulic jets is being used to scour a ship berth at the Port of Grays Harbor on the coast of Washington. The system has been in place...

The Truck Commodity Survey in the New York-New Jersey Metropolitan Area
The Truck Commodity Survey was designed to gather information on the characteristics of truck traffic at toll barriers with minimal disruption to traffic flows. It was developed by the...

Aerodynamic Modeling of Chimneys
The wake induced acrosswind behavior of circular cross-section structures, such as industrial chimney, has been studied for many years using wind tunnel models. Due to the relaxation of...

Analysis of Barrier Island Dynamics for Ship Channel Planning at Ship Island, Mississippi
Ship Island is located among a chain of barrier islands approximately 18 km south of Biloxi, Mississippi. During initial construction of Gulfport Harbor Ship Channel, 1901-1905, the channel...

Erosion and Washover in Coastal Louisiana
In 1985 three hurricanes affected the barrier coastline (Caminada-Moreau Headland) of Louisiana. These produced severe coastal erosion and rapid washover extension. Using the 1979 U.S.G.S....

In Situ Determinations of Dispersion and Transport Parameters at Piraquara De Fora (RJ)?Brazil, With Help of a Fluorescent Dye Tracer
This paper deals with 'in situ' determinations of the transport and dispersion parameters at Piraquara de Fora cove, near the site where the first Brazilian nuclear...

Application of Field Proven Fine Bubble Membrane Aeration Technology
Fine bubble membrane diffusers represent a significant technological advancement in diffused aeration technology by providing the consistently high transfer efficiencies of fine bubble...

Radon Entry & Control Versus Indoor Dynamics
The measurements of air infiltration, interzonal transport and exfiltration as the diagnostic procedures have been significantly influential in the selection, implementation and evaluation...

A Method for Design and Evaluation of Rapid Sand Filters Treating Secondary Effluents
The information presented in this paper provides a framework for analysis of rapid sand filter performance. Process variables are quantitatively related to filter design variables in a...

Design and Construction of Slow Sand Filters
The belief that large area requirements are necessary is based on old concepts and contemporary engineering designs that overstate area requirements. Large area requirements result from...

Estimating Soil Gas Flow Rates and Identifying Entry Routes in a Dwelling Using Multiple Perfluorocarbon Tracers
Passive monitoring of indoor air and below basement floor (subslab) soil gas for radon and perfluorocarbon tracer (PFT) gas concentration was conducted to investigate the influence of...

Indoor Radon: Site Evaluation
The soil parameters most important in evaluating the indoor radon potential of a building site are the soil radium concentration, the soil-gas radon concentration and the permeability...

Pressure Differences Affecting Radon Entry in New Residential Construction
Various conditions in a house can commonly produce house negative pressures up to 20 Pascals relative to the soil gas pressure. Depressurization of the house relative to the soil gas will...

Peat Filtration for Oil Removal
An investigation was carried out to assess the potential of horticultural peat produced in Saskatchewan as a filter medium in treating five oil-in-water emulsions (standard mineral oil,...

Quantitative Dye-Tracing of Karst Ground-Water Flow
Analysis of the results of repeat quantitative dye traces between a sinkhole and a spring used for public water supply were used to describe predictive relations between discharge, mean...

Computerized Data Processing, Displays and Groundwater Flow Analyses of the Stringfellow Hazardous Waste Site
Several types of data, maps, and figures were obtained from various sources involved in the investigations and monitoring at the site. This information was discretized, and a computerized...
