Striking a Balance - A Guide to Coastal Dynamics and Beach Management in Delaware
2004
This report provides historical background and knowledge of coastal dynamics and beach management in Delaware, outlines the forces affecting Delaware's beaches - including the balance between development and protection of coastal resources, and explains statewide coastal management policies and the measures taken to mitigate the effects of erosion.

National Assessment of Coastal Vulnerability to Sea-Level Rise: Preliminary Results for the Atlantic Coast
1999
One of three national assessments of U. S. coastal regions conducted in the late 1990's, this assessment focused on the Atlantic coastline, while the other two focused on the Gulf Coast and Pacific coastlines. The overall goal of these studies was to identify those portions of the U. S. coastal regions at risk and the nature of that risk (e. g. , inundation, erosion, etc. ). The long-term goal of this study is to predict future coastal changes with a degree of certainty useful for coastal management, following an approach similar to that used to map national seismic and volcanic hazards.

Lessons Learned from Delaware Lidar
A case study of Delaware's efforts to obtain LiDAR elevation maps of its coastline and the lessons that can be learned from the process, this short report may be useful to other states or localities looking to assess impacts from sea level rise and storm surge using LiDAR technology. After describing Delaware's need for LiDAR data in its coastal planning process, the authors address the specific lessons the state learned. These lessons relate to the need for properly scoping and defining a LiDAR mapping project, the need for data standardization, and the need to ensure that end users (in this case, planners) are sufficiently competent with information systems to put the elevation data to good use.

Patterns and Projections of High Tide Flooding Along the U.S. Coastline Using a Common Impact Threshold
February 2018
The National Oceanic and Atmospheric Administration (NOAA) analyzes "high tide flooding" (also known as "nuisance flooding") in this report, and finds that it is becoming more commonplace due to sea level rise. High tide flooding impacts roads, beaches, parks, and private property, and is generally more disruptive than damaging. However, there are places such as Norfolk, Virginia; San Diego, California; and the U. S Marshall islands where it is currently a serious problem. Even more, with continued sea level rise, flooding is likely to increase.

Recommendation of Sea Level Rise Planning Scenarios for Delaware: Technical Report
2017
The Delaware Department of Natural Resources and Environmental Control (DNREC) first developed Recommended Sea Level Rise Scenarios for Delaware in 2009. In 2016-2017, a new Delaware Sea Level Rise Technical Committee was convened to update the scenarios based on the latest scientific research and modeling. Led by Delaware Geological Survey and DNREC Delaware Coastal Programs, the Committee and these sea-level rise (SLR) planning scenarios respond to 2013 Executive Order 41 - which requires Delaware state agencies to factor SLR into capital improvement projects and land use decisions, and for DNREC to periodically update SLR scenarios with the best scientific data available.

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.

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. .

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.

Climate Change Tree Atlas
October 26, 2010
The Climate Change Tree Atlas helps determine current and future suitable habitat and distribution of 134 tree species in the Eastern United States based on current climate and projected suitable habitat for the year 2100. The Atlas provides detailed information on environmental characteristics defining these distributions for each species, and can be used to develop large-scale projections of species responses to climate change. By taking current distributions of tree habitat in the U. S.
