Pore Water Pressures in Unsaturated Soils
Unsaturated soils are three-phase systems composed of solid mineral matter, water, and air. Such soils may be formed by either natural or artificial means. Except in moist environments,...

Determining the True Distributions of Load in Instrumented Piles

Water Gravity Waves Generated by a Moving Low Pressure Area

Characterization of Particle Class Sizes Associated with Indicator Organisms in Stormwater
The presence of pathogen indicators is the leading cause of water body impairment in the United States, accounting for over 15% of the waters currently requiring TMDL development (USEPA,...

Laboratory Modeling of Vibro-Driven Piles

Modelling of Displacement Piles in Sand Using a Pressure Chamber

Structural Expression in Wind Sensitive Structures
Architectural details can impact both the local cladding pressures on a structure as well as the overall structural response. Figure 1 shows a pair of roof corner vortices on the upper...

Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...

Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...

Leakage Control—Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...

Control of Microorganisms in Drinking Water
Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. ...

Quality Control Test for Prestressing Wires in Concrete Pressure Pipe
Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts...

Control of Microorganisms in Drinking Water by Pressure-Driven Membrane Processes

Comparison of Hydrodynamic Parameters for a Floating Breakwater
The U. S. Army Engineer Research and Development Center is in the process of developing a Rapidly Installed Breakwater System (RIBS) for use in Joint Logistics Over the Shore Operations...

Entire Load-Displacement Characteristics for Direct Shear Failure of Concrete

Compaction Effects Induced in Cohesionless Soils by Installation of Pressure-Injected Footings

High Resolution Pressure Measurements on Roofs of Low Buildings
Describing an instrumented module which was built with extremely high pressure tap density to use as a component of a roof or wall....

Predicting Droughts for the South Platte River System
In this paper we apply probability theory and stochastic processes to determine drought properties, particularly drought duration. Spccilicslly, we model the sequences of wet and dry years...

Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
