Climate Change and the Delaware Estuary: Three Case Studies in Vulnerability Assessment and Adaptation Planning
June 2010
This report summarizes the major changes expected in the Delaware Estuary due to climate change as well as the threats to three key resources: tidal wetlands, drinking water and bivalve shellfish. These three resources served as case studies representative of the Estuary's habitats, human/water interaction, and living resources respectively, allowing investigation of climate change impacts and potential adaptation strategies in the Estuary.

A Method to Assess Climate-Relevant Decisions: Applications in the Chesapeake Bay (External Review Draft)
June 2010
The goals of EPA’s Global Change Research Program (GCRP) are to assess the potential effects of climate change on water quality, air quality, ecosystem health, and human health, and to provide decision makers with information and tools that enable them to incorporate considerations of climate change into their decision making processes.

Trends in Extreme Precipitation Events for the Northeastern United States 1948-2007
March 2010
Based on the number and frequency of extreme precipitation events since the release of their 2005 report, entitled "Indicators of Climate Change in the Northeast," the authors sought to update information for this particular indicator in the Northeast, and apply more rigorous analysis to better enable local communities to take appropriate actions.

Delaware 2017 Coastal Inundation Maps
2017
Delaware's Department of Natural Resources and Environmental Control (DNREC) and the scientists from Delaware Coastal Programs have developed Sea Level Rise (SLR) inundation maps for the state as an online interactive tool. The maps show the possible impacts of inundation based on various SLR scenarios for Delaware’s waterways and watersheds. The maps are a representation of inundation based on local Mean Higher High Water (MHHW), which is the long-term average of the higher of the daily high tides.

Coastal Inundation Toolkit
The Coastal Inundation Toolkit was developed by the Digital Coast Partnership Group to help communities understand and address coastal inundation issues - where water covers what is normally dry land. Information and resources are organized into 5 stages: understanding coastal inundation, identifying community risks and vulnerabilities, creating inundation maps, communicating risks and vulnerability, and discovering what others are doing to address inundation. For each of these 5 areas, explanations and guidance are provided with links to the specific resources available from Digital Coast to support that specific step in the process, making this a user-friendly way to support assessments and planning for sea level rise and extreme weather events.

The Likelihood of Shore Protection Data Set
2009
This site provides the GIS data that was used for the study "State and Local Governments Plan for Development of Most Land Vulnerable to Rising Sea Level along the U. S. Atlantic Coast," published by James Titus. The GIS data are available in three formats: grid, polygon shape files, and vector shape files. This data identifies shoreline development and areas that will be vulnerable to sea level rise. .

Town of Bowers Beach, Delaware Coastal Resiliency Planning
2009
With support from the Delaware Department of Natural Resources and Environmental Control (DNREC), the Town of Bowers Beach is developing a Coastal Resiliency Action Plan to increase resiliency and reduce hazard vulnerability to the current and future effects of coastal storms and climate change. Bowers Beach currently experiences a number of coastal related problems including flooding of streets, episodic storm damage, coastal erosion, and other coastal hazard impacts.

Recommended Sea Level Rise Scenarios for Delaware
December 2009
The Recommended Sea Level Rise Scenarios were established by the Delaware Department of Natural Resources and Environmental Control (DNREC) Sea Level Rise (SLR) Technical Workgroup to support the development of the DNREC Sea Level Rise Policy. The SLR Technical Workgroup is comprised of scientists from DNREC, University of Delaware, Partnership for the Delaware Estuary and the Center for the Inland Bays. The Workgroup determined the Delaware SLR scenarios by employing published expert summaries of existing data and predictions from national and international panels and federal agencies.

State and Local Governments Plan for Development of Most Land Vulnerable to Rising Sea Level along the U.S. Atlantic Coast
October 27, 2009
Based on the analysis of planning data and current policies of 131 state and local land use plans from Massachusetts to Florida, the study identifies those coastal areas likely to be affected by rising water levels and classifies them based on the extent of development already in place and the potential for future development. The report explains that the existing extensive development on the Atlantic coast creates the need for coastal protective structures, which could negatively impact wetlands.
