Dissertations - ALL
Global and regional environmental disturbances, including harvesting and climate change, can lead to integrated and interactive effects on forest ecosystems, altering their structure and function, and therefore long-term sustainability. Understanding both short- and long-term impacts of harvesting practices (e.g., cutting rotation length, intensity) on forest dynamics is a key factor in developing criteria and guidelines for sustainable forest management practices. Process ecosystem models are useful tools to improve predictive understanding of complex, interacting ecological process and their response to disturbance. Few studies have rigorously tested model simulations against field measurements which would provide more confidence in efforts to quantify logging …
The Interacting Hydrologic Responses To Changing Climate, Watershed Physical Characteristics, River Regulation, And Land Development In The Northeastern United States, Rouzbeh Berton
Dissertations - ALL
In this dissertation, the scale-dependency of hydrologic responses due to changing climate and regime shifts of large-scale circulation patterns and their teleconnection patterns were evaluated using long-term precipitation and discharge records in sub-basins with no development, and extensive development and riverine impoundments of the Merrimack River watershed. The Merrimack (New Hampshire-Massachusetts) is a 13,000 km2 forested (67%) watershed located in the northeastern United States. The overarching goal of this dissertation was to assess hydrologic responses to the potential effects of changing climate in sub-basins experiencing a range of development in order to help guide sustainable water management in the Merrimack …
