Participatory Modeling Of Tidal Circulation On Maine Mudflats To Improve Water Quality Management Of Shellfish Areas, Gabrielle V. Hillyer Dec 2019

Participatory Modeling Of Tidal Circulation On Maine Mudflats To Improve Water Quality Management Of Shellfish Areas, Gabrielle V. Hillyer

Electronic Theses and Dissertations

Over the past decade, researchers have become increasingly aware of the vital role stakeholder knowledge plays in understanding complex social and environmental problems. Incorporating stakeholder knowledge into understanding complex problems allows for greater awareness and identification of community needs and can help build partnerships to support the development of applied research. In this thesis, I demonstrate the value of stakeholder knowledge and research partnerships by focusing on the soft-shell clamming industry in Maine and how a complex collaboration between clammers, municipal officials, representatives from state agencies, researchers, and other partners relied on and build adaptive capacity to address complex water …


Improved Estimates Of Tributary Nitrogen Load To Casco Bay, Maine, Whitley J. Gray Aug 2019

Improved Estimates Of Tributary Nitrogen Load To Casco Bay, Maine, Whitley J. Gray

Electronic Theses and Dissertations

Over the past two decades, total nitrogen (TN) concentrations have increased in Casco Bay (CBEP 2015). The sources of the increased nitrogen are poorly understood but occur with simultaneous population growth and land use changes. The total riverine nitrogen load to Casco Bay was previously estimated by Liebman and Milstead (2012) using the United States Geologic Survey’s (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model. The SPARROW model uses watershed characteristics, regional monitoring data and nitrogen source data to estimate nitrogen loading but was not validated using measurements of nitrogen in the Casco Bay watershed. This study attempts to …
