Preparing Water Supply Systems For Climate Change: The Role Of Hydrologic Forecasting In The Northeast, Leslie Decristofaro
Preparing Water Supply Systems For Climate Change: The Role Of Hydrologic Forecasting In The Northeast, Leslie Decristofaro
Doctoral Dissertations
Fresh water is a resource strongly impacted by climactic conditions. Water supply systems in the northeastern United States will see the effects of climate change on their water quality and quantity in various ways, including changes in seasonality of flows, changes in the frequency and magnitude of extreme precipitation events, and changes in the variability of precipitation and water availability. Five northeastern water supplies examined are expected to maintain at least 95% monthly reliability over a range of climates wider than the current projections. However, model results indicate that turbidity levels in New York City's Ashokan Reservoir will change with …
Evaluating Policy And Climate Impacts On Water Resources Systems Using Coupled Human-Natural Models, Hassaan Furqan Khan
Evaluating Policy And Climate Impacts On Water Resources Systems Using Coupled Human-Natural Models, Hassaan Furqan Khan
Doctoral Dissertations
Extensive human intervention in the terrestrial hydrosphere means that virtually every river basin globally reflects the interaction between human and natural hydrologic processes. Thus, sustainable watershed management needs to not only account for the diverse ways humans benefit from the environment but also incorporate the impact of human actions on the natural system. Informed policy making to address our water challenges requires a comprehensive understanding of these feedbacks and how they might be affected by future changes in climate. This work develops coupled human-natural models for improved surface water and groundwater management in water-scarce regions under future changes in climate. …
Flood Risk Assessment, Management And Perceptions In A Changing World, Katherine Schlef
Flood Risk Assessment, Management And Perceptions In A Changing World, Katherine Schlef
Doctoral Dissertations
Floods are a global challenge that is increasing due to changes in climate and human populations. Using an interdisciplinary approach, this work contributes novel methodologies and knowledge to three key challenges associated with floods. The first chapter builds upon the atmospheric and statistical sciences to provide a general methodology for climate informed approaches to projecting long-term flood events based on large-scale ocean-atmospheric processes. The second chapter builds upon the engineering, decision analysis, and economics disciplines to integrate climate-informed projections with decision-scaling, a decision-making under uncertainty framework, to further flood risk management. The third chapter builds upon the social sciences to …
Predicting Effects Of Climate Change And Sea Level Rise On Hydrologic Processes In A Mid-Atlantic Coastal Watershed, Rui Li
Civil & Environmental Engineering Theses & Dissertations
This dissertation assessed impacts of Climate Change (CC) and Sea Level Rise (SLR) on coastal hydrologic processes using the Lynnhaven River watershed as a test bed. The watershed is part of Chesapeake Bay Watershed and hydraulically connected with mid-Atlantic Ocean. Six CC scenarios were considered in terms of eight Regional Climate Models’ predictions for three Intergovernmental Panel on Climate Change (IPCC) emission assumptions, namely, B1, A1B, and A2, for two future periods, namely 2046 to 2065 and 2081 to 2099. The ensemble means of downscaling results from four methods were used to represent the future climates. On the other hand, …
A Detailed Hydrodynamic Study To Help Community Based Resiliency Planning Under Extreme Climatic And Weather Events, Md. Golam Rabbani Fahad
A Detailed Hydrodynamic Study To Help Community Based Resiliency Planning Under Extreme Climatic And Weather Events, Md. Golam Rabbani Fahad
Theses and Dissertations
The State of New Jersey is particularly vulnerable to extreme weather and climatic events. This study concentrates on spatial and temporal vulnerability of these events using climate and hydrodynamic modelling. The first chapter focuses on historical climatic trend of temperature and precipitation as well as the future scenarios using 10 bias corrected climate model output considering high end emission scenario derived from Coupled Model Intercomparison Project Phase 5 (CMIP5). In the second chapter a coastal hydrodynamic model called ADCIRC-2DDI was implemented to assess the impact of hurricanes in the Western North Atlantic (WNAT) model domain. The efficiency of the model …
