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...

A Coupled Mass Transfer and Surface Complexation Model for Uranium (VI) Removal from Wastewaters
A remediation technique has been developed for removing uranium (VI) from complex contaminated groundwater using flake chitin as a biosorbent in batch and continuous flow configurations....

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...

Computer simulation of pulsed pumping for remediation under mass transfer limited conditions
The article presents the computer simulation of choosing the right time periods for interruption and pumping in the pulsed pumping process. It will calculate a set of criteria under mass...

Modeling of Biofiltration of Natural Organic Matter in Drinking Water Treatment
A multi-substrate model of the biofiltration of natural organic matter in drinking water was developed and successfully applied. This model assumes that biofiltration is a two-step process...

Quantification of the Mechanisms Controlling the Removal Rate of Volatile Contaminants by Air Sparging
Air sparging is a technology for removing dissolved and volatile phase chemicals (VOCs) from the saturated zone. It is used in conjunction with soil vapor extraction (SVE) and sometimes...

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...

Development of a Model for the ABF/AS Process
A modelling approach has been established for the activated biofiltration/activated sludge (ABF/AS) process. This approach indicates that ABF/AS systems can be considered as a variation...

Modeling Full-Scale Diffused Aeration Systems
The purpose of this research was to show the direct relationship of the oxygen mass transfer coefficient (K_La_T)...

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...

Measurements of the Hydrodynamic Lift and Drag Forces Acting on Riprap Side Slope
Direct measurements have been made of lift and drag forces acting on a 20.1 mm spherical particle placed within the riprapped 1.5 H: 1 V side slope of a 10 m long channel which was protected...

Impact of GOES Data on Surface Heat Flux Predictions
Surface heat flux is the required input for the Great Lakes Forecasting System (GLFS) in order to predict three dimensional temperature structure of the Great Lakes. Since the flux is...
