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 …
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 …
The Belknap Campus And Metro Louisville Urban Heat Island Effect: Air And Ground Surface Temperature Analysis, Kenyetta Johnson
The Belknap Campus And Metro Louisville Urban Heat Island Effect: Air And Ground Surface Temperature Analysis, Kenyetta Johnson
Undergraduate Arts and Research Showcase
Numerous studies show that urban morphologies and land covers generate excess heat emissions and retain heat relative to surrounding rural areas, known as the Urban Heat Island (UHI) effect. Urban fabrics paved by concretes and asphalts absorbs solar radiation during solar peak then radiates heat after sundown. This study investigates temperature distribution data related to the UHI effect on the Belknap campus at the University of Louisville, which represents a small aerial sample of the Louisville metropolitan UHI effect. The objective of this study is to measure the reflectivity of ground surfaces and air temperatures on the Belknap campus during …
