Non-Intrusive Rayleigh Wave Measurement System for Soil Profiling in Ports
Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and...
Terminal Asphalt Patching: An Innovative Approach
Asphaltic concrete has dominated the terminal industry as the pavement of choice for years. It is readily available and economical to install but requires considerable maintenance expense....
Scheduling of Ground Water Pumpage in Alluvial Aquifers to Minimize the Impact on Surface Water Diversions
The purpose of this paper is to present a methodology to administer the withdrawal of ground water from a basin where stream-aquifer systems are hydraulically connected. The administrative...
Feasibility of Water Supply for City of Houston Subsidence Zones Five and Six
The purpose of this paper is to evaluate the feasibility of providing surface water to the Harris Galveston Coastal Subsidence District (HGCSD) Zones Five and Six (located in North Houston...
System Operating Strategies in Water Rights Modeling and Analysis
The appropriative surface water rights permit structure in Texas has provided the impetus to develop TAMUWRAP, a river basin simulation package that will allow the response of multiple...
Hillsboro Basin Surface Water Management Model
This study presents the results of the hydrologic and hydraulic analysis of the 103-square mile Hillsboro Basin located in South Florida. The purposes of the project were to develop a...
Concrete Surface Treatments?A Selection Guide
Concrete deterioration can take many forms. The most common forms of concrete surface deterioration includes delaminations, spalling and scaling. This deterioration is usually caused by...
A Theoretical Approach to Characterize Reinforced Concrete Using Stress Waves
Although advances in nondestructive evaluation of structural concrete have been made, the ultrasonic determination of the placement of steel reinforcement in concrete remains difficult....
Innovations for NDT of Concrete Structures
The proposed paper presents three recent innovations for sonic and ultrasonic Non-Destructive Testing (NDT) of concrete structures which greatly increase the utility and speed of many...
Taming Environmental Data
The main problem with environmental management is the vast quantity of data generated for and by analysis. A computer system designed to solve this problem moves data from the database...
Wave Slamming on a Horizontal Circular Cylinder
The present paper describes an experimental study of the wave slamming force on a horizontal circular cylinder located near the free surface. The vertical force on a cylinder and the corresponding...
Equivalent Statistical Quadratization of Nonlinear Hydrodynamic Loads on TLPs
In this paper, a new method is proposed for the expansion of nonlinear drag forces expressed in terms of multivariate Hermite polynomials correct up to the second-order. The drag force...
Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...
Future Technology for Disbonding Snow and Ice from Pavements
Current techniques to remove ice and compacted snow from pavement surfaces are costly because they needlessly crush or melt most of the ice layer. Also, in many cases they do not accomplish...
Effects of Heterogeneity on Actinide Diffusion Rates in Tuffaceous Rock
The pore structure and mineralogy of Topopah Spring Tuff are heterogeneous on scales less than one cm. This heterogeneity creates spatial variation in transport rates for aqueous actinide...
Fractal Characteristics of Fracture Roughness and Aperture Data
In this study mathematical expressions are developed for the characteristics of apertures between rough surfaces. It shown that the correlation between the opposite surfaces influences...
Nondestructive Testing Using Borehole and Surface Seismic Techniques to Evaluate Rock Mass Damage Zones
A suite of seismic tests was performed at the U12g tunnel at the Nevada Test Site. The methods include borehole (crosshole and downhole) and surface (Rayleigh wave and refraction) tests....
An Empirical Data Base for the Investigation of Earthquake-Related Changes in Crustal Hydrology
Both fracture permeability and fluid flow velocity can alter as a result of sudden strain changes associated with earthquake fault rupture. Testing the hydrological signatures of numerous...
Ground Water: How Contaminated?
It is common knowledge that ground waters, like surface waters, are endangered by pollution from a variety of human activities. Commonsense approaches to the problem are overshadowed by...
Aquifer Restoration: Which Method?
Ground-water contamination is an increasing problem, especially in large urban areas. Toxics that seep into water supplies threaten the health of the community and it's difficult...
