Evaluating Soil Moisture and Hydraulic Conductivity in Semi-Arid Rangeland Soils
The United States Department of Energy's Office of Civilian Radioactive Waste Management (DOE-OCRWM) Fellowship Program supports various disciplines of academic research related to the...

Inference of Moisture Content in Unsaturated Media Using Ultrasonics
This study focuses on the ability of commercial ulltrasonics equipment to determine the moisture content in unsaturated media. We are interested in the possible application of this technology...

Channel Network Models for Solute Migration and Dispersal
We introduce a class of channel-network models for solute migration and dispersal in saturated rock. In discussing the behaviour of any dispersive process it is necessary to compare and...

The Best of Both Worlds: Integrating Statistical and Deterministic Approaches to Area Remediation
We seek a complete framework for adaptive area characterization for purposes of remediation, incorporating both statistical and deterministic features. This hybrid methodology involves...

Project on Contaminations-Radiation-Ecosystems-Health in Russia
We would like to discuss with you a project that we are currently developing, doing research upon and completing. In our report we represent the the following: - a few experimental data...

Flow Visualization and Relative Permeability Measurements in Rough-Walled Fractures
Two-phase (gas-liquid) flow experiments were done in a natural rock fracture and transparent replicas of natural fractures. Liquid was injected at constant volume flow rate, and gas was...

Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...

Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...

A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...

Optimum Operation of Recharge Basins
Mathematical models based on nonlinear programming are developed for operating recharge basin systems. The objective of these optimization models is to determine the operation policy that...

The City of Los Angeles Gray Water Pilot Project Shows Safe Use of Gray Water is Possible
A year-long study of eight residential gray water systems was conducted in the City of Los Angeles. Soils irrigated with gray water were compared monthly with soils irrigated with municipal...

A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...

Expert System for the Preloading Method of Ground Improvement
Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...

A Simulation of the Quake-response on the Frame with Large Basement-box under the Earthquake from Deep Soil Layer
This paper treats a study of computing vibratory analysis and its comparison with measurements for the earthquake-responses on an actual 19 storied pure frame-structure with its height...

A Computational Method for Acquiring Response and Ground Motion from Accelerogram on the Base of Structure
This paper describes computational formulation of vibratory equations for acquiring response and input ground motion from accelerogram on the base of long structure with flexible slab....

Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...

High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...

Shotcrete for Underground Support VI
This proceedings consists of papers presented at the Shotcrete for Underground Support VI Conference held in Niagara-on-the-Lake, Ontario, Canada, May 2-6, 1993. It covers three broad...

The Role of Information for Offshore Natural Gas
Natural gas may play a larger role in the Nation's energy mix. Extensive reservoirs of natural gas exist on the Outer Continental Shelf (OCS). But exploration for oil and gas on the OCS...

The Value of the Federal Oil/Gas OCS and Its Required Nexus with the Changing Perceived Quality of Rights
A particular few of thousands of hardly distinguishable and certainly previously undistinguished Federal OCS oil/gas tracts can suddenly become prizes of great value. Vice versa, prized...
