Long Term Performance of Raft and Footing Foundations Above Clayey Silt
Two multistorey buildings have recently been constructed on a 30-m thick layer of clayey silt in downtown Fredericton, New Brunswick. The Bank of Montreal building is ten storeys high...
Consolidation Settlements and Pore Pressure Dissipation
A test fill was constructed off the coast of one of the outer islands in Hong Kong to evaluate the consolidation characteristics of a soft plastic clay deposit known as Hong Kong mud....
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
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,...
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...
Waste Minimization and Recycling by Microfiltration during Nitrocellulose Manufacturing
A plant survey was conducted to determine the amount of nitrocellulose (NC) discharged with process water from each of five sequential NC purification processes. Wastewater samples were...
A comparison between computed and measured bed evolution in a river bend
A shallow-water scheme with a movable bed has been employed in order to check the reliability of computations related to the bed evolution when a substantially three-dimensional phenomenon...
Measurement of Turbulent Properties in a Natural System
Instruments designed to measure flow properties in stratified estuaries, lakes and oceans are reviewed. Emphasis is given to the measurement of turbulent fluxes and recent developments...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...
Mapping 2-D and 3-D Velocity Components in Circular Conduits Using an Electromagnetic Current Meter and a 5-Hole Pilot Probe
The techniques presented in this paper facilitate the visualization of the two-dimensional and three-dimensional flow fields at arbitrary sections in a conduit. They have been used to...
Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...
Experimental Design and Measurement Techniques for Investigation of Two-Phase Flow
Discussing the relevant hydraulical and inter-phasial processes of two-phase flow in open tanks the necessary requirements for set-up and operation of physical model studies are worked...
Sediment Measurement Instrumentation A Personal Perspective
The development of the suspended sediment samplers in the 1940s was a major contribution to the science of sedimentation and provided for the proper development of dams, reservoirs, and...
Low-Cost Bridge Scour Measurements
This paper reports on the use of a low-cost, highly portable sonar system. The ease of use of the instrument and the short time required to make measurements should make this system valuable...
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...
An Investigation of Turbulence in Open Channel Flow via Three-component Laser Doppler Anemometry
A three-component laser Doppler anemometer is used to reexamine the distribution of single-point mean statistics in a nearly uniform fully-developed 2D turbulent open channel flow of water...
Hot-Film Response in Three-Dimensional Highly Turbulent Flows
A methodology is described for accurate turbulence measurements with hot film or hot wires even at turbulent intensities as high as 100%. The assumptions involved and the approximations...
Experimental Study on Turbulent Structures in Unsteady Open-channel Flows
Turbulence measurements in unsteady open-channel flows over smooth beds were conducted accurately by the simultaneous use of two-component LDA system and water-wave gauges. In the inner...
Estimation of Mean Velocity for Flow Under Ice Cover
Methods of estimating mean velocity in a vertical from point velocity measurements are compared for an ice-covered channel. The comparison is based on velocity profiles obtained from a...
