Footing Modulus Near Slopes
A method is described for estimating the footing modulus of shallow spread foundations located near slopes of cohesionless material. The ratio of footing modulus for a shallow foundation...

Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...

Load-Settlement Prediction of Footings on Steep Slopes
The use of spread footings on slopes is a common practice in the design of bridge foundations. Footings are generally constructed in the slope or at its crest to minimize the bridge length,...

The Role of Shale Pores in Settlement
Waste fills resulting from the mining of coal in Appalachia should ideally consist of large, free-draining sedimentary rock fragments. The successful performance of these embankments is...

Settlement of Peats and Organic Soils
New advances in investigation of settlement of peats and organic soils and issues related to construction over such soft ground are presented. Peats and organic soils are well known for...

Settlement of Dynamically Compacted Deposits
This paper compares predicted and measured settlements of deposits that were densified by means of dynamic compaction. Settlement records are presented for sites consisting of old, midage,...

Experimental Study of the Settlement of Shallow Foundations
This article describes the main results obtained experimentally by the French Bridge and Road Research Laboratories on the settlement of shallow foundations under centered vertical loads....

Settlement Analysis for 450 Meter Tall KLCC Towers
The site evaluation and settlement analysis performed for the two tallest buildings in the world currently under construction, are described. The site evaluation resulted in shifting building...

Movement of Foundations on Rock
This paper reviews methods for estimating the settlement of vertically loaded foundations on rock, with particular emphasis on shallow and piled foundations in and on soft rock....

Load Settlement curve Method for Spread Footings of Sand
A newly developed method is presented to predict the complete load settlement curve for square spread footings on sand loaded at their center with a vertical load and with an embedment...

Test and Prediction Results for Five Spread Footings on Sand
A separate volume summarizes this prediction symposium. It is available from ASCE in New York and is entitled as listed above. This prediction event took place during the conference and...

Federal Risk Management Policy: Where Are the Problems?
Federal risk management policy involves both risk assessment and risk management elements. Risk assessment consists of hazard identification, dose-response assessment, exposure assessment,...

Poorer Is Riskier: Opportunity for Change
With regard to water resources, it is appropriate to build upon two interacting themes of the late Aaron Wildavsky (1988). The first of Wildavsky's themes is the idea of resiliency. The...

Uncertainty and Time Preference in Shore Protection
From a review of economic, psychologic, and geographic literature, three points of criticism of the economic model of choice are 1) when faced with losses, individuals tend not to be averse...

Behavioral, Social, and Institutional Aspects of Risk Analysis
The paper summarizes the third session of the conference which discussed four items that become pitfalls for decision makers when neglected. These are parameter uncertainties as distinct...

Optimization Studies of Anaerobic Expanded Bed Reactor Pretreatment of Domestic Wastewater
In recent years the advent of the anaerobic expanded bed reactor (AEBR) has made possible the treatment of wastewaters of comparatively lower strength than have traditionally been treated...

Effect of Roughness and Thickness of Biofilms on External Mass Transfer Resistance
The effect of roughness and thickness of biofilms on the dissolved oxygen (DO) concentration boundary layer thickness (DO CBLT) and the external mass transfer process in a biofilm system...

Using the SedBed Monitor to Measure Bed Load
An acoustic distance measuring device (SedBed Monitor) was developed to accurately measure bed surface transects in a sediment and water recirculating flume. From these transects the rate...

On Measurements of Particle Spinning Motion
Investigation of particle saltation motion is crucial to the development of the theory of bed load transport. Due to the combination effects of the bed roughness and the velocity gradient,...

Visual Investigation of Field Bed-Load Sampling
An instrument for bed load sampling was developed consisting of an underwater video camera for visual observations. This instrument is called the Delft-Nile sampler and its design, efficiency...
