Assessment And Prediction Of Surface Water Vulnerability From Non-Point Source Pollution In Midwestern Watersheds, Fadhil K. Jabbar
Assessment And Prediction Of Surface Water Vulnerability From Non-Point Source Pollution In Midwestern Watersheds, Fadhil K. Jabbar
Doctoral Dissertations
"Non-point source pollution is the leading cause of impairment in surface water in the Midwest. In this research, we seek to predict which watersheds are most vulnerable to point source pollution without field sampling using publically available GIS databases. Watersheds with higher vulnerability ratings can then be targeted for water quality monitoring, and funds used to improve watershed health can be distributed with greater efficacy. To better understand and target watershed vulnerability, we used three different approaches. In the first project, 35 sub-watersheds were sampled in the Lower Grand Watershed, which is a highly agricultural watershed in northern Missouri/southern Iowa. …
A Field Validation Of Dam Indexing Methods In Mississippi, Steven Thomas Fox
A Field Validation Of Dam Indexing Methods In Mississippi, Steven Thomas Fox
Electronic Theses and Dissertations
Indexing methods are applied to dam inventories throughout the United States to assist in prioritizing resources to maintain aging dam structures. Three published indexing methods and one proposed method were applied to 24 dams through Mississippi. The majority of dams in Mississippi have little to no information concerning the performance records or design specifics of a given dam. Field assessments were conducted to determine the physical condition of each dam, identify potentially deficiencies at dams, and calculate a consequence in the event of a dam failure. The results of the four indexing methods will be compared and advantages and disadvantages …
