GEOMECHANICAL ANALYSIS OF THE GEOTHERMAL RESERVOIR AT SAN EMIDIO, NEVADA AND FRACTURE TOUGHNESS ANISOTROPY OF EGS COLLAB TESTBED ROCKS
(2022-05)The WHOLESCALE (Water and Hole Observations Leverage Effective Stress Calculations and Lessen Expenses) project is aiming to simulate the spatial distribution and temporal evolution of stress throughout the geothermal ... -
Impact of Increasing Freight Loads on Rail Infrastructure from Fracking Sand Transportation
(2014-01-03)The increased use of the hydraulic fracturing technique, used extensively in the United States, for oil and natural gas extraction, has significantly expanded the frac sand market and impacted freight rail corridors. This ... -
Impacts of Changing Frozen Ground Regimes on Groundwater Recharge
(2021-06)The spring snowmelt accounts for a large percentage of annual groundwater recharge in northern latitudes. Many factors control the proportion of snowmelt that becomes groundwater or runoff, including the volume of snow, ... -
INFLUENCE OF COUPLING EROSION AND HYDROLOGY ON THE LONG-TERM PERFORMANCE OF ENGINEERED SURFACE BARRIERS
(2012-08-26)The main goal of this study was evaluate design strategies that couple erosion and hydrology for barriers of low level radioactive waste (LLRW) disposal facilities. This objective was met by conducting long-term (1000 yr) ... -
Investigation of Non-Uniform Erosion at the Kenosha Sand Dunes in Wisconsin
(2022-08-31)Coastal erosion is both a natural and anthropogenically induced earth process that can be costly to landowners, communities, and valuable ecosystems. Often, it is a complex issue that can occur at variable rates in both ... -
Leaching from Roadways Stabilized with Additive Coal Combustion Products (CCPs): Data Assessment and Synthesis
(2015-05-17)Approximately 37% of the electrical power used in the United States is generated by coal-fired power plants. Air pollution control systems installed on coal-fired power plants collect solid byproducts of coal combustion, ... -
Low-Cost Instrumentation Development Using Independent, Self Contained Microcontrollers
(2019)This thesis describes the development and testing of low-cost geophysical and field instrumentation using microcontrollers. While open-source microcontroller boards have traditionally been developed for hobbyists and ... -
MEASUREMENT AND MODELING OF THERMAL PROPERTIES OF COARSE-GRAINED SOILS
(2014-07-03)The purpose of this study is to experimentally determine and mathematically represent the thermal resistivity or thermal conductivity dry-out curves (TRDCs or TCDCs) quantifying the relation between thermal resistivity or ... -
MECHANICAL AND POROELASTIC PROPERTIES OF LITHOLOGIC UNITS WITHIN THE SAN EMIDIO GEOTHERMAL SYSTEM, NEVADA, UNITED STATES
(2022-08-31)The primary objective of the WHOLESCALE project is to simulate the temporal evolution and spatial distribution of stress in and around the geothermal reservoir at San Emidio, Nevada, United States. To constrain stress ... -
Mechanical Behavior of Polyurethane Stabilized Fouled Ballast (PSFB)
(2014-05-18)The United State Federal Railway Administration (FRA, 2010) estimates that the demand for rail freight transportation (tonnage) will increase 88% by 2035. North American railroads spend about $3.4 billion every year on ... -
MECHANICAL PROPERTIES OF POORMAN SCHIST AND WESTERLY GRANITE
(2019)We investigate the influence of foliation orientation and fine-scale folding on the static and dynamic elastic properties and unconfined strength of the Poorman schist. The Poorman schist is the dominant rock type at ... -
Methods for Testing the Effect of Hydraulic Gradient on the Polymer Elution of Polymer GCLs
(2018-01-03)Geosynthetic Clay Liners (GCLs) were developed in the 1980’s as an alternative landfill liner or cover material. GCLs are primarily comprised of a layer of processed sodium bentonite (Na-B), generally 7-10 mm thick, ... -
Multi-Sourced Geologic Data Integration: A Time-Based Approach
(2018-01-03)Complications in geological modeling are often made worse by the wide range of formats in which geologic data are stored. When crossing state lines, the names and interpretations of geologic formations may vary, individual ... -
NATURE AND FATE OF PFAS IN A STAGNANT ICE TERRAIN SAND AND GRAVEL AQUIFER
(2022-08-31)Detection of per- and polyfluoroalkyl substances (PFAS) in concentrations above EPA health advisory limits in 2019 led to closure of two of the five City of Rhinelander municipal water wells. The wells are in close ... -
Particle Scale Dynamics of Coarse Granular Material
(2018-01-04)Developing a new wheeled or tracked vehicle for military use typically involves physical prototyping of preliminary vehicle designs and field tests to evaluate their performance in a range of conditions. Computational ... -
PARTICULATE ORGANIC MATTER TRANSPORT IN EXPERIMENTAL RIVERBED SAND COLUMNS
(2021-08)Abstract The hyporheic zone is a hot spot for coupled transport and biogeochemical reactions at the aquatic-terrestrial interface. The influx of particulate organic matter (POM), a biological colloid, into the near-surface ... -
POTENTIAL CLIMATE CHANGE IMPACTS TO STREAM TEMPERATURE IN THE MARENGO RIVER HEADWATERS
(2019)ABSTRACT Cold-water trout habitat in Wisconsin is projected to significantly decrease as a result of climate change. The extent of habitat loss depends, in part, on groundwater discharge to the stream, which can provide ... -
Residential and District-Scale Ground-Coupled Heat Pump Performance with Fiber Optic Distributed Temperature Sensing
(2015-05-17)Ground-coupled heat pumps (GCHP) have garnered considerable attention in recent years as an energy-saving alternative to conventional space heating and cooling systems, but there exists some debate about their effectiveness ... -
