The Cardinal Edge
Citizen science refers to a discipline of scientific projects that utilize public participation and collaboration to complete or supplement a collected data set. Our study as a whole aims to assess the greenhouse gas (GHG) source-sink status of small, constructed wetlands in Kentucky through field and remotely sensed data. Additional facets of the project include evaluating the influence of the primary producer community on GHG uptake and emissions, and our ability to identify healthy small wetlands from science and community-based perspectives. Specifically, the citizen science aspect intends to assess both (1) gaps between knowledge of the general public regarding wetland …
Presence Of Severe Acute Respiratory Syndrome Coronavirus 2 In Urban Streams Receiving Sewer Overflow, Louisville, Kentucky, Usa., Cullen Hunter
Presence Of Severe Acute Respiratory Syndrome Coronavirus 2 In Urban Streams Receiving Sewer Overflow, Louisville, Kentucky, Usa., Cullen Hunter
Electronic Theses and Dissertations
Pathogens may enter surface waters as they are shed in human feces and potentially delivered to surface waters via sewer overflows, particularly in the eastern United States. This study examined of the presence of fecal indicators in two forks of Beargrass Creek in Louisville, Kentucky. Surface water grab samples (N=30), sediment samples, water quality, and a paired wastewater surveillance study were analyzed. SARS-CoV-2 was detected in a single stream sample despite ubiquitous presence of the virus within the area in wastewater and consistent evidence of a human fecal indicator. These findings demonstrate the need for more green and gray infrastructure …
Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman
Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman
Electronic Theses and Dissertations
Soil erosion is of escalating importance as increasing population and climate change have put increasing pressures on agricultural food production. Vegetation and precipitation are two factors that control the amount of soil erosion extant within a region. Sediment delivery ratios (SDRs) assess the ratio of soil eroded from a watershed system that is permanently removed from the system through stream sediment discharge. Using 1) river discharge and sediment concentration data and 2) the Revised Universal Soil Loss Equation (RUSLE), this thesis analyzes fluctuations in monthly SDRs for an average hydroclimatological crop-harvest season for the Senachwine Creek watershed, IL. Through calculating …
Assessing Predictors Of Harmful Algal Blooms In The Western Lake Erie Basin., Katherine M. Weigle
Assessing Predictors Of Harmful Algal Blooms In The Western Lake Erie Basin., Katherine M. Weigle
Electronic Theses and Dissertations
Harmful algal blooms (HABs) have been a recurring issue in the Western Lake Erie Basin for more than a decade, despite policies implemented to improve the water quality of the Great Lakes. HABs describe algae that can be harmful to both ecosystem function and human health. The Western Lake Erie Basin, in particular, experiences Microcystis aeruginosa blooms in the summer months due to a multitude of factors leading to increased phosphorus and nitrogen loads in the contributing watersheds. In this study, lake water surface temperature, land cover, river discharge, and precipitation were examined as potential triggers for the occurrence and …

Assessing The Curve Number Method For Modeling Urban Watershed Stormwater Runoff Across Louisville, Ky., Garrett J. Seay
Electronic Theses and Dissertations
According to the US EPA when a watershed reaches 75% impervious land cover, surface runoff accounts for 55% of precipitation input losses compared to 10% for a ‘natural cover’ watershed, exacerbating urban flooding during extreme rainfall events. This research modeled historical rainfall-runoff processes for six urban watersheds within the city of Louisville, KY for a series of these extreme rainfall events. Precipitation and resultant runoff discharge events were collected in the field over the spring and summer of 2016. Surface biophysical data in the form of gridded elevation, land cover and soil type were also collected and processed for each …
An Analysis Of The Relationship Between Snowpack And Groundwater Across Utah Watersheds., Samuel Wright
An Analysis Of The Relationship Between Snowpack And Groundwater Across Utah Watersheds., Samuel Wright
Electronic Theses and Dissertations
This thesis examined what type of relationship existed between snow water equivalence (SWE) volume and groundwater elevation within six sub-watersheds in Utah. Data was gathered on SWE from seventeen SNOTEL sites and groundwater elevation data was gathered from six continuously monitored groundwater wells. This data was gathered for January through May for 2011, 2013, and 2014 in order to represent the water conditions that were above average, below average, and average respectively. Using MLR formulas the total SWE for each sub-watershed was determined for each year/month. Afterwards a correlation analysis was performed to determine if any association existed between SWE …
Urban Flooding And Sewer Inundation On The University Of Louisville Belknap Campus., Justin T. Hall
Urban Flooding And Sewer Inundation On The University Of Louisville Belknap Campus., Justin T. Hall
Electronic Theses and Dissertations
Over the past few decades on the University of Louisville Belknap campus urban flooding has become more frequent as a result of surface water runoff and sewer inundation. This urban flooding is a result of ongoing watershed urbanization and rapid expansion of the local sewer system to accommodate the expanding city of Louisville. However little research has been conducted on this issue, despite continued flooding on and adjacent to campus. Using the EPA Storm Water Management Model (SWMM) we applied a dual drainage modeling approach that combines both surface and subsurface drainage data to produce a flood hydrograph at the …
