An Empirical Water Quality And Best Management Practice Prioritization Model For Select Arkansas Watersheds, James Mccarty
An Empirical Water Quality And Best Management Practice Prioritization Model For Select Arkansas Watersheds, James Mccarty
Graduate Theses and Dissertations
The purpose of this study was to prioritize subwatersheds using water quality data and watershed characteristics. Water quality data was provided through studies by the Arkansas Natural Resources Commission, Beaver Water District, Arkansas Water Resources Center, and publicly available USGS gage data. A total of 114 sites across five HUC-8 watersheds were analyzed, including 12 USGS gages. Watershed characteristic data was retrieved from USGS and Arkansas GeoStore geodatabase repositories. A significant linear relationship between baseflow and stormflow nutrient concentrations was established allowing for the use of baseflow concentrations in the prioritization methodology. Pearson correlation, linear regression, classification and regression tree, …
Evaluation Of The Equations Used To Calculate Hydraulic Conductivity Values From Two-Stage Borehole Tests, Johnathon Dale Blanchard
Evaluation Of The Equations Used To Calculate Hydraulic Conductivity Values From Two-Stage Borehole Tests, Johnathon Dale Blanchard
Civil Engineering Undergraduate Honors Theses
A compacted clay liner (CCL) test pad was constructed for the purpose of evaluating the testing procedures utilized for determining hydraulic conductivity of a CCL. These procedures include ASTM D6391 (2014) Method C and ASTM D6391 Method A. Method C was recently added to ASTM D6391(2014) and was evaluated based upon comparison of results obtained from previous research with results from the data presented herein. The test pad was instrumented with volumetric water content probes and water matric potential sensors to monitor the wetting front in the soil. The data obtained from this instrumentation should be used to develop a …

Numerical Modeling Of Fluid Migration In Hydraulically Fractured Formations, Toyin Christie Aseeperi
Graduate Theses and Dissertations
Economic production from low permeability shale gas formations has been made possible by the introduction of horizontal drilling and hydraulic fracturing. To ensure that gas production from these formations is optimized and carried out in an environmentally friendly approach, knowledge about the patterns of gas flow in the shale reservoir formation is required. This work presents the development of a shale gas reservoir model for the characterization of flow behavior in hydraulically fractured shale formations. The study also seeks to develop more computationally efficient approaches towards the modeling of complex fracture geometries. The model evaluates the migration patterns of gas …
