Modeling Response Of Water Quality To Land-Use And Climate Change In Lake Auburn, Me, Nicholas Messina
Modeling Response Of Water Quality To Land-Use And Climate Change In Lake Auburn, Me, Nicholas Messina
Electronic Theses and Dissertations
Lake Auburn, Maine, USA, is a historically unproductive lake that has experienced multiple algal blooms since 2011. The lake is the water supply source for a population of ~60,000. We modeled past temperature, and concentrations of dissolved oxygen (DO) and phosphorus (P) in Lake Auburn by considering the watershed and internal contributions of P as well as atmospheric factors, and predicted the change in lake water quality in response to future climate and land-use changes. A stream hydrology and P-loading model (SimplyP) was used to generate input from two major tributaries into a lake model (MyLake) to simulate physical mixing, …
Tide And Storm Surge Dynamics In Estuaries Of Variable Morphology, Preston Spicer
Tide And Storm Surge Dynamics In Estuaries Of Variable Morphology, Preston Spicer
Electronic Theses and Dissertations
Storm surges are the most destructive component of coastal storms, and climate change is predicted to enhance the frequency of intense storm events in the future. Currently, most storm surge forecasting assumes linear surges and the extent to which this assumption leads to model inaccuracies is currently unknown. The goals of this research are to characterize storm surge in estuaries and determine the contribution of nonlinear tide-surge interaction to total inland surges. A citizen science experiment was conducted in four estuaries in Maine. Results show the estuary shape influences surges through convergence, friction and man-made constrictions. These mechanisms modified total …
Perspectives On Water Resources Risk, Policy, And Stewardship, Anne Marie Lausier
Perspectives On Water Resources Risk, Policy, And Stewardship, Anne Marie Lausier
Electronic Theses and Dissertations
Water management approaches have historically optimized water for human use and placed lower emphasis on the relationship between ecosystems and humans. Despite efforts to balance human and ecosystem needs, existing management approaches tend to prioritize some needs, knowledges, and values over others. Natural and anthropogenic changes pose challenges to water governance institutions due to policy inflexibility, and may lead to ecosystem degradation, water stress, and conflict among water users. This work seeks to redress these shortcomings through three scholarly contributions. First, a conceptual framework for Water Resources Stewardship is developed in support of equitable and adaptive solutions under changing conditions. …

This issue of Minerva includes a farewell from departing Honors Dean, François Amar; an article on the new service-learning course HON 175 and the course's inaugural Hurricane Island experience; and a deep dive into the Servant Heart Research Collaborative and the group's visit to Sierra Leone, Africa. Other highlights include reflections by a number of Honors faculty who returned from sabbatical; and a look into 2019-2020 student thesis research and internship experiences.
