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 ... -
Rock Mechanics Laboratory Tests Relevant to the in-situ Stress Measurements at the 4850-level, Homestake Mine, Lead, South Dakota
(2018-01-03)Laboratory rock mechanics experiments were conducted on cores taken from the Sanford Underground Research Facility (SURF) (formerly of Homestake Mine) in Lead, South Dakota. Strength properties and their anisotropy were ... -
Seasonal Monitoring of an Infiltration Experiment Using Time-Lapse Geophysics and Chemical Characterization to Understand Nitrate Transport in the Vadose Zone
(2023)Nitrogen-based chemical fertilizers and manure are used throughout Wisconsin to provide nutrients for crops. However, nitrogen from these fertilizers may leach from the surface and root zone to the groundwater, creating ... -
SEISMIC ARRAYS FOR THE IMAGING OF ALLUVIAL DEPOSITS AND MONITORING ENGINEERING SYSTEMS
(2019)As part of the PoroTomo Project, active and passive seismic data were collected with a three component seismometer array in order to image petrophysical properties of a 1500-m by 500-m by 400-m volume in a geothermal ... -
STATE DOT ENVIRONMENTAL AND ECONOMIC BENEFITS OF RECYCLED MATERIAL UTILIZATION IN HIGHWAY PAVEMENTS
(2016-09-30)The use of recycled materials in highway construction has the potential to achieve significant benefits affecting the triple-bottom line (environment, prosperity and society). Although state departments of transportation ... -
