Coastal Erosion--Causes, Erosion Control Methods, Economic and Environmental Impacts, and Best Management Practices

Coastal erosion is an important and constant issue facing coastal areas all over the world today. The rate of coastal development over the years has increased, in turn requiring that action be taken to protect structures from the threat of erosion. A review of the causes of coastal erosion and the methods implemented to control it was conducted in order to determine the best course of action in response to coastal erosion issues. The potential positive and negative economic and environmental impacts are key concerns in determining whether or not to restore an eroding beach and which erosion control method(s) to implement. Results focus on providing a comparison of these concerns as well as recommendations for addressing coastal erosion issues.

The Identification of Best Management Practices in a Materials Recovery Facility to Increase Solid Waste Diversion in the Department of Defense (DoD) Installations along the Front Range of Colorado to Satisfy the DoD Solid Waste Diversion Goal of 40 Percent

The five installations operated by the Department of Defense (DoD) in the Front Range region of Colorado do not meet the DoD non-hazardous solid waste diversion goal of 40 percent, further impacting landfills and generating greenhouse gases. This applied capstone project identifies and evaluates best management practices of a Materials Recovery Facility (MRF), qualitatively and quantitatively, to increase solid waste diversion at a DoD MRF. An environmental benefits model quantified the externalities of increasing solid waste diversion at the installations. By implementing best management practices at a MRF, the DoD would divert an additional 1,400 tons of solid waste per year, resulting in the equivalent of 1,502,567 gallons of gasoline being saved, among many benefits presented in this capstone.

Comparative Evaluation of Groundwater Management Practices of the Ogallala Aquifer

Mining of groundwater, or extracting a larger quantity of water than what is naturally returned to the aquifer through recharge, has been occurring for more than fifty years. The minimal natural recharge to the Ogallala Aquifer makes sustainable use of this resource a daunting task for states across the High Plains that rely on it to support their well-established ways of life. This task is compounded when considering the different combinations of federal, state and local governance, as well as regional economic and social frameworks that each state overlaying the aquifer experiences. This project critically examines factors contributing to groundwater management successes and failures of three states that overlay the majority (87%) of this resource: Nebraska, Kansas and Texas.

The Timber Wolf Preservation Society: Developing a Management Plan for Long Term Sustainability & Prosperity

The timber wolf has been eradicated from most of its North American range, but in recent decades has been recovering. The Timber Wolf Preservation Society (TWPS) was founded to assist in the reestablishment of wolf populations in Wisconsin. The public education mission of the TWPS is a key element in increasing human tolerance of wolves. This capstone summarizes principles of wolf ecology and the care of captive mammals. Challenges faced by the TWPS, including more effective board management practices and the need for a strategic plan, are also identified. Suggestions and recommendations for improving the TWPS administration, board governance and organizational growth are presented to allow the TWPS to become sustainable and continue to contribute to wolf recovery efforts in Wisconsin.

Paddlefish Management in Missouri

Paddlefish populations have begun to decline throughout their historic range but are still found in 22 states in the southeastern and midwestern United States. This capstone project investigates problems facing paddlefish management including, pollution, habitat loss, poaching, and the illegal caviar trade. A combination of four management options is beneficial for the species by increasing public knowledge and awareness of what paddlefish require for survival, allowing paddlefish to be used as a natural resource. After comparing a typical state paddlefish management plan and the plan developed and used in Missouri, it is apparent that a national paddlefish management plan template is necessary for affected states. A plan provides direction for effectively maintaining paddlefish stocks, according to state specific management goals.

Nutrient Load Reduction: Challenges facing the Chesapeake 2000 Agreement

The Chesapeake Bay is the largest estuary in the United States supporting a complex ecosystem that sustains many habitats and the organisms that depend on them. The bay also supports economic, recreational, and cultural activities to over 16 million people residing in the watershed. Changes within the watershed have caused excessive levels of nutrients, mainly nitrogen and phosphorous, to pollute the bay. The Chesapeake Bay Program, guided by a complex agreement, was created to address these and other issues and oversee the restoration of the bay. The most recent version of this agreement, the Chesapeake 2000, declares its continued commitment to restore the bay with over 100 goals to be met by the year 2010. Reports show that although intensive efforts have been made to promote nutrient reduction, very little reduction has actually resulted. This project described these efforts. The final results reveal obstacles affecting progress, shortcomings to current approaches and possible solutions for future implementation.

Performance Septic Systems: Does an Advanced Septic System Provide Adequate Treatment on Black Hammock Island and is there Adequate Regulatory Policy to Ensure Integrity?

This project determined if the performance based septic system, proposed for a development on Black Hammock Island in Jacksonville, Florida, is the best choice to prevent environmental contamination from septic tanks and if adequate regulatory policy exists. Research shows a central wastewater treatment plant provides the most efficient pollutant removal but can be cost prohibitive. This project found performance based systems surpasses conventional septic system performance and are more suited and economical to remote areas without sewer service. This project finds current regulations to be inadequate and supports ordinance changes proposed by the Mayor of Jacksonville to enhance the current policy and provide more adequate and meaningful regulation.
