Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman May 2020

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 …


Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, Evan Cobey Apr 2020

Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, Evan Cobey

Undergraduate Theses and Capstone Projects

Renewable sources of energy remove dependence on fossil fuels. When renewable sources are adopted, they reduce damage to the environment from burning fossil fuels. Currently, fossil fuels are cheaper to produce, causing renewable energy to be used less. In the United States, fossil fuels receive heavy subsidies, keeping renewable energy in the periphery. This research explores the environmental and economic effects of subsidizing fossil fuels. Findings include that governments and citizens lose money when fossil fuels are subsidized. While subsidization initially makes them cheaper, they create expenses that are not factored into original costs, such as damage to human health …


Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch Jan 2020

Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch

Gulf and Caribbean Research

I spent my nearly 50—year career in marine science working at marine laboratories, most of that as a chief executive officer. So, it is appropriate that my reflections are about marine laboratories, rather than my own science. After relating my career course, I turn my attention to the history and development of marine laboratories along the U.S. coast of the Gulf of Mexico (GOM). Surprisingly, the region’s first laboratory was actually constructed in 1903 at Cameron, LA, but operated less than a decade before closing. It was not until after World War II that the university—affiliated marine laboratories of today …
