Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...

Additional Benefits from Channel Improvements
This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction...

Marginal Wharf and Embankments?Seismic Design
This paper presents some of the seismic considerations used for the improvements at Berths 225 to 229 at the Port of Los Angeles. The design of the improvements was complicated by the...

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...

CAD Mapping Trailblazer
Until three years ago, few civil/surveying firms had automated both surveying (including digital recording of angles and distances shot in the field) and the related design and drafting....

Use of SPT and CPT Tests for Evaluating the Liquefaction Resistance of Sands
A cone penetration test (CPT)-liquefaction resistance relationship has been established using the large body of standard penetration test (SPT) data. Factors for relating CPT tip resistance...

Laboratory and Field Evaluation of Cone Penetrometers
Cone penetrometers from 8 organizations have been studied by performing laboratory tests and field tests. The testing show that pore pressure and temperature zero shift affect significantly...

Site Characterization Using the Cone Penetrometer Test
The Cone Penetrometer Test (CPT) when used in conjunction with a limited soil boring program can provide a more detailed and economical site characterization. This paper addresses how...

Effect of Cementation on the Cone Penetration Resistance of Sand
A laboratory study was conducted to investigate the effect of cementation on the cone penetration resistance of sand. A new apparatus to form homogeneous artificially cemented sand specimens...

Skin Friction Evaluated From Friction Meter Test
This paper first describes the features of a specially developed friction meter and its operation method, and then reports in-situ test results conducted on various types of soils at two...

Uplist Capacity of Pile Foundations Using CPT Data
Southern California Edison Company has performed field uplift load tests on concrete driven piles, cast-in-place straight shaft piles and cast-in-place belled piers along transmission...

N-Values Used to Predict Settlements of Piles in Egypt
A method is proposed for using the standard penetration N-values to predict the load-settlement curves for different piles used in Egyptian soils. The method is based on H. G. Poulos-E....

Designing for Maintainability
Inspection and maintenance guidelines are unavailable for many buildings. Building owners seldom have the benefit of such information because buildings are often considered passive systems,...

Effect of Particle Size on Sludge Dewaterability
Using a modified Buchner funnel apparatus to measure specific resistance and a sequential centrifugation/filtration procedure to fractionate a sludge, it was possible to more precisely...

Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...

Seawater Intrusion in Salinas Valley, California
The rate of intrusion has been estimated to be about 19,000 acre-feet per year. If no action is taken to halt the intrusion, it is projected that in the year 2000 there will be as much...

Deferred Drainage?Prudent Policy or Tactical Folly?
The practice of deferring drains has not always worked out as planned. This is particularly true of large outlet drains such as the San Luis Drain in the Central Valley of California and...

Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...

Reservoir Sedimentation and Desilting in Taiwan
The island of Taiwan is infested with numerous flashy streams with steep slopes and huge sediment loads, thus, the major reservoirs have experienced heavy sediment deposit. The encroachment...

Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...
