Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...
Los Angeles and Long Beach Harbors Tidal Circulation Study
Expansion of harbor facilities frequently involves placement of additional landfill and the deepening of channels and mooring areas. A numerical tidal circulation model was used in the...
Lifeline Seismic Risk Analysis?Case Studies
These papers employ design concepts and procedures in lifeline seismic risk analysis. Two of the papers describe the seismic hazards in the northwestern United States. A systems model...
Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...
Tallying Water Resources Goals
Federal water resources planning philosophy has undergone a lengthy evolution with a number of refinements in the past decade to encompass environmental laws and the political philosophy...
Treating Sewage in One Tank
A sequencing batch reactor (SBR) was the answer to a sewage problem that was holding up community development in Poolesville, MD. Poolesville was one of the first municipalities in the...
Drying Out
Treatment plants are most efficient when they're treating waste, not water. Spurred on by increased fuel prices, a number of new technologies have been developed that can...
Bugs and Carbon Make a PACT
At its Chambers Works in southern New Jersey, DuPont was ordered to sharply reduce the BOD load in the wastewater it discharged to the Delaware River. Out of this mandate came the PACT...
Physics-Based Modeling of Lakes, Reservoirs, and Impoundments
This book provides an overview of considerations that apply to modeling flow and transport in lakes, reservoirs, and impoundments using equations based on conservation principles. Specific...
Deformation Characteristics of Cohesionless Soils from In Situ Tests
This paper is a summary of seven years experience gained by the National Electricity Board of Italy (ENEL), ISMES and Technological University of Turin in assessing these parameters using...
Pressuremeter and Foundation Design
The design of shallow and deep foundations on the basis of pressuremeter results is analyzed using numerous load tests and case histories. The foundations are shallow footings subjected...
Field Permeability Test for Earthen Liners
A sealed double-ring infiltrometer (SDRI) was developed for in-situ measurements of the hydraulic conductivity of earthen liners and covers. The characteristic of the SDRI that distinguishes...
Pressuremeter Correlations for Preconsolidated Clay
Conventional triaxial compression and consolidation tests are often utilized to obtain parameters for design of foundations. More recently, Menard pressuremeter test results have been...
Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
Flat Dilatometer Tests in Calibration Chambers
This paper presents the results of a series of Flat Marchetti's Dilatometer Tests (DMT's) performed in a large Calibration Chamber (CC) on dry Ticino (TS) and...
Residual Soil Settlement From Pressuremeter Moduli
The Menard pressuremeter test is briefly described, and practical drilling techniques are summarized for Piedmont residual soils. Applications and limitations of the pressuremeter are...
Landslide Investigations Using the Weight Penetrometer
The weight penetrometer is a light weight device and can be easily deployed on slopes not accessible to conventional exploratory tools such as drill rigs or cone penetrometers. The weight...
Liquefaction Study of Coal Refuse by Nuclear Gauges
This paper presents a technique for utilizing nuclear gauges to determine density and moisture content continuously throughout refuse embankments and slurry reservoirs. The nuclear measurements...
Waterfront Electric Cone Penetration Testing
Offshore deployment methods developed for use by the oil industry were combined with less expensive nearshore drill barge technology. This resulted in the successful completion of cone...
Dilatometer Tests for the Design of Grouted Piles in Rock
A case study of drilled and grouted piles in rock, which were analyzed using results of down-hole dilatometer tests is presented. The tests were performed from a jack-up platform in water...
