The Mixing Of A River Into Coastal Waters At Two Beaches: Environmental Factors, E. Coli Contributions And Applications For Predictive Models, Adrian Jordan Koski

Theses and Dissertations

Beach closures and public health protection are confounded by analytical procedures that result in delays in notification of adverse water quality conditions and the lack of affordable analytical methods to identify pollutant sources. Attempts have been made to develop predictive frameworks using ancillary hydrometeorological data to statistically anticipate deteriorated water quality. Many urban coastal beaches are impacted by river runoff. In Kenosha Wisconsin, beach sanitary survey data from two beaches adjacent to the mouth of the Pike River were examined to ascertain whether simple river-lake mixing models identified river influence on coastal water quality and improved predictions of beach advisories. …

Addressing Potential Risks And Challenges Of Co2 Geologic Sequestration, Ethan Guyant

Theses and Dissertations

Carbon Capture and Geologic Storage is a viable technology to reduce the concentration of CO2 emitted to the atmosphere, however there remains challenges and risks associated with implementing this technology. One of the challenges, and the focus of Chapter 2, is maintaining the injectivity of the reservoir throughout the entire injection period of a project. While potential risks include the pressurization of the reservoir and the leakage of CO2 and/or brine out of the storage reservoir which is the focus of Chapter 3. A consequence of injecting dry-supercritical CO2 is that it results in salt precipitation in the near well …

A Soil Parameters Geodatabase For The Modeling Assessment Of Agricultural Conservation Practices Effects In The United States, Mauro Di Luzio, Martin L. Norfleet, Jeffrey G. Arnold, Jimmy R. Williams, James R. Kiniry

International Journal of Geospatial and Environmental Research

Soil parameters for hydrology modeling in cropland dominated areas, from the regional to local scale, are part of critical biophysical information whose deficiency may increase the uncertainty of simulated conservation effects and predicting potential. Despite this importance, soil physical and hydraulic parameters lack common, wide-coverage repositories combined to digital maps as required by various hydrology-based agricultural water quality models.

This paper describes the construction of a geoprocessing workflow and the resultant hydrology-structured soil hydraulic, physical, and chemical parameters geographic database for the entire United States, named US-SOILM-CEAP. This database is designed to store a-priori values for a suit of models, …
