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 …
Evaluating The Use Of Suas-Derived Imagery For Monitoring Flood Protection Infrastructure, Eleanor Mei Dietz
Evaluating The Use Of Suas-Derived Imagery For Monitoring Flood Protection Infrastructure, Eleanor Mei Dietz
Electronic Theses and Dissertations
In the US there are approximately 33,000 miles of levees. This includes 14,500 miles of levee systems associated with US Army Corps of Engineers programs and approximately 15,000 miles from other state and federal agencies. More than 14 million people live behind levees and associated flood prevention infrastructure. Monitoring and risk assessment are an on-going process, especially during times of flood conditions. The city of New Orleans was heavily impacted by Hurricane Katrina in 2005 by storm surges and intense rainfall. The impact of the hurricane was substantial enough to cause levee failure and I-wall toppling where many of the …
Historical Groundwater Data Analysis Of The Wilcox Aquifers In Lafayette County, Mississippi, Adam Schildhammer
Historical Groundwater Data Analysis Of The Wilcox Aquifers In Lafayette County, Mississippi, Adam Schildhammer
Electronic Theses and Dissertations
Lafayette County, Mississippi, is located in the northern central part of the state and relies on groundwater resources for all of the municipal water needs in the county. The population is increasing in the county; therefore, groundwater withdrawals are as well. With such a high demand on groundwater, it is important to have an understanding of the historical trends of the groundwater levels to determine is the population is over pumping the available supply. The Meridian-upper Wilcox aquifer and the lower Wilcox aquifer are the two groundwater sources for the county. In order to fully understand the behaviors of these …
Use Of Seismic Refraction In Determining Rock Mass Anisotropy, Mohammad Najmush Sakib Oyan
Use Of Seismic Refraction In Determining Rock Mass Anisotropy, Mohammad Najmush Sakib Oyan
Electronic Theses and Dissertations
Seismic refraction is a popular method used by geological/geotechnical engineers to understand subsurface conditions. This method along with information collected from borings produce a realistic image of the ground beneath us. The goal of this study is to define and test a set of procedures to use seismic refraction alone to create high quality images of subsurface conditions. The focus is on areas with several meters of soil overlain by bedrock. The application of these procedures will minimize construction costs by eliminating the need for multiple boreholes. The results show that two important criteria must be met for successful application …
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 …
