Simulation Of Wave Propagation In Granular Particles Using A Discrete Element Model, Syed Tahmid Hussan
Simulation Of Wave Propagation In Granular Particles Using A Discrete Element Model, Syed Tahmid Hussan
Electronic Theses and Dissertations
The understanding of Bender Element mechanism and utilization of Particle Flow Code (PFC) to simulate the seismic wave behavior is important to test the dynamic behavior of soil particles. Both discrete and finite element methods can be used to simulate wave behavior. However, Discrete Element Method (DEM) is mostly suitable, as the micro scaled soil particle cannot be fully considered as continuous specimen like a piece of rod or aluminum. Recently DEM has been widely used to study mechanical properties of soils at particle level considering the particles as balls. This study represents a comparative analysis of Voigt and Best …
Developing A Calibrated Seepage Meter To Measure Stream-Aquifer Interaction In The Mississippi Delta, Wesley J. Bolton
Developing A Calibrated Seepage Meter To Measure Stream-Aquifer Interaction In The Mississippi Delta, Wesley J. Bolton
Electronic Theses and Dissertations
The Mississippi Alluvial Plain (MAP) is a premier region for irrigated agriculture in the United States producing approximately 9 billion dollars in annual revenues. The region receives around 138 cm of precipitation annually; however irrigation is necessary to maximize crop yields as most of the precipitation does not occur during the growing season. There are 8 million irrigated acres within the Mississippi Alluvial Plain. The source of most of the irrigated water is the surficial aquifer in the Mississippi Embayment the Mississippi River Valley Alluvial Aquifer (MRVAA) and due to the reliance on irrigation for maximum crop yields recent potentiometric …
Groundwater Transfer And Injection Pilot Project: Construction Of A Three Dimensional Groundwater Flow Model, Wesley Bluvstein
Groundwater Transfer And Injection Pilot Project: Construction Of A Three Dimensional Groundwater Flow Model, Wesley Bluvstein
Electronic Theses and Dissertations
The Mississippi River Valley Alluvial Aquifer has experienced substantial groundwater declines in eastern Arkansas and northwest Mississippi due largely to irrigation for rice corn soybeans and other water intensive crops. To alleviate groundwater decline and ensure future sustainability of water resources the U.S. Department of Agriculture has in conjunction with the U.S. Geological Survey and the University of Mississippi initiated studies to determine potential avenues of remediation. Options include improved irrigation efficiency installation of surface weirs inter-basin transfers and groundwater transfer and injection. This study develops a three-dimensional groundwater flow model of a withdrawal well adjacent to a river for …
Field Implementation Of Tire Derived Aggregate As Lightweight Backfill For Retaining Walls, Jeremy Labbe
Field Implementation Of Tire Derived Aggregate As Lightweight Backfill For Retaining Walls, Jeremy Labbe
Electronic Theses and Dissertations
The objective of this study was to determine the effectiveness of Tire Derived Aggregate (TDA) as embankment and retaining wall backfill material using data from two field projects supplemented by data from previously published studies. Data collected from the two projects included horizontal earth pressure, resultant forces and moments acting in the wall stem, tensile and compressive forces within the wall, moments at the base of the wall, settlement of the TDA, time dependent temperature fluctuations within TDA, pore pressure changes in underlying foundation soil, movement of the wall face, and movement of the embankment. Data Collection was completed by …
