Mud Mountain Dam Concrete Cutoff Wall
Mud Mountain Dam is an earth and rockfill flood control dam on the White River. The dam is located approximately 50 km southeast of Seattle, Washington. The dam was constructed in 1941...

Bureau of Reclamation Experience with Innovative Solutions to Increased Design Floods
Over the last several decades advances in the hydrologist's ability to estimate floods have resulted in increases to the design floods for many existing drainages. As with other dams throughout...

Geotechnical Modifications at Meeks Cabin Dam
This paper presents a summary of the geologic and geotechnical evaluation of a potential piping deficiency identified at Meeks Cabin Dam as well as description of remedial measures and/or...

Geometric Design Projects for Highways
An Introduction
This book provides an introduction to geometric design of highways by means of examaples and projects that emphasize basic specifications, approaches to preliminary route selection, alignment,...

Hanford Waste Vitrification Project Overview and Status
The Hanford Waste Vitrification Project (HWVP) is being constructed at the U.S. Department of Energy's Hanford Site in Richland, Washington. The paper gives an overview of the HWVP which...

Investigation of Fracture-Matrix Interaction: Preliminary Experiments in a Simple System
Paramount to the modeling of unsaturated flow and transport through fractured porous media is a clear understanding of the processes controlling fracture-matrix interaction. As a first...

Role of Fracture Zones in Controlling Hydraulic Head and Groundwater Flow?Experience from Site Characterization Program in Finland
The preliminary site investigations for the final disposal of HLW produced by TVO have been carried out during 1987 - 1992 in five areas. All the areas consist of Precambrian crystalline...

Sensitivity and Probabilistic Analyses of Ground Water Travel Time in a Fractured and Variably-Saturated Geologic Medium
This paper presents a method for sensitivity and probabilistic analyses of performance of a hypothetical nuclear waste repository located in a layered, fractured, and variably-saturated...

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...

Hydropulse Tomography for Identifying 3-D Permeability Distribution
For the purpose of identifying subsurface permeability distribution, a geotomographic method named Hydropulse Tomography (HT) was developed. As observation data, HT uses hydraulic pressure...

An Inverse Procedure for Estimating the Unsaturated Hydraulic Conductivities of Volcanic Tuffs
A procedure is developed for estimating the hydraulic conductivity function of unsaturated volcanic tuff, using measurements of the sorptivity and capillary pressure functions. The method...

Modeling of Fluid and Solute Transport in Fractured Rock
A new model for flow and solute transport in fractured rock is proposed. It is based on the concept of a network of channels. The individual channel members are given stochastically selected...

Solute Transport Characteristics of Fractured Dolomite in Southern Nevada, USA
Recirculating tracer tests in fractured Cambrian dolomite beneath the Amargosa Desert revealed (1) and 83-percent increased in apparent dispersivity resulting from a two-percent increase...

Open Channels in Fractures Maintained by Deposition and Erosion of Colloids
Colloids initially suspended in the water in fractures can deposit onto the fracture surfaces, and will partially or fully clog the fracture. The amount of clogging will depend on whether...

Thermal-Hydraulic Analyses of Molten Glass in a Joule-Heated Melter
Physical modelling using glycerine and three-dimensional mathematical modelling were executed to study temperature and flow profiles of molten glass in the melter for the vitrification...

Mine Support, Radiation and Ventilation Control with Spray-on Barriers
The use of spray-on liner agents to provide localized excavation support in place of traditional techniques such as shotcrete or bolts-and-screen has been the subject of extensive investigation....

A Homogeneous Equilibrium Model for Analysis of Spent Fuel Shipping Containers
Transportation of nuclear spent fuel is inevitable over the coming years. However, in order to ensure the safety of such transport, computational models must be established, which are...

Aperture Characteristics, Saturated Fluid-Flow, and Tracer-Transport Calculations for a Natural Fracture
We used surface-profile data taken with a noncontact laser profilometer to determine the aperture distribution within a natural fracture and found the surfaces and apertures to be isotropic....

Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...

Modeling Gravity-Driven Fingering in Rough-Walled Fractures Using Modified Percolation Theory
Pore scale invasion percolation theory is modified for imbibition of wetting fluids into fractures. The effects of gravity, local aperture field geometry, and local in-plane air/water...
