Oyster River (New Hampshire) Culvert Analysis Project

March 2010

In this project the Piscataqua Region Estuaries Partnership (PREP) performed a vulnerability assessment of the hydrology and drainage system of the Oyster River watershed in southeastern New Hampshire and its capacity to adapt to climate change impacts and increased development. The project used a geographic information system (GIS) based watershed model to identify the road/stream crossing culverts that are vulnerable to failure due to extreme storms with increased precipitation, in combination with development of the watershed.

Assessing the Risk of 100-Year Freshwater Floods in the Lamprey River Watershed of New Hampshire Resulting from Changes in Climate and Land Use

2010

This NOAA funded project is assessing flood risk associated with existing and future land use and climate change scenarios for the Lamprey River watershed of Great Bay, New Hampshire to support land use decision-making. Key products include maps at the watershed and municipality scale of the 100-year flood risk boundaries and river discharge at specific locations under selected land use and climate change scenarios.

A Discussion of the Potential Impacts of Climate Change on the Shorelines of the Northeastern USA

July 10, 2007

This report, prepared for the 2007 Northeast Climate Impact Assessment (see separate entry), provides a broad overview of how sea-level rise will impact the coast of the northeastern United States. Different possible rates of sea-level rise and the primary impact of shoreline retreat is discussed. The report explains how local features determine the extent of shoreline retreat in a given area and addresses how sea-level rise could affect different ecosystems, including estuaries, salt marshes, and barrier island systems.

Confronting Climate Change in the U.S. Northeast: Science, Impacts, and Solutions

July 2007

This report describes the changing climate for the U. S. Northeast region and associated climate change impacts. Both high and low emission scenarios were analyzed to assess the impacts of two very different future climates on the region's coastal areas, marine fisheries, forests, agriculture, winter recreation, and human health sectors. Mitigation and adaptation policy options relevant to Northeast are presented, and the report includes a discussion on how to prioritize adaptation strategies.

Potential Climate Change Impacts on Marine Resources of the Northeastern United States

2007

This report synthesizes an assessment of potential changes in marine ecosystems off the northeastern United States in response to projected climate and emission scenarios, with a focus on temperature effects on living marine resources. It reviews likely impacts on the northeast continental shelf, and highlights potential effects on the distribution and abundance of the American lobster and Atlantic cod to illustrate the range of possible impacts throughout the region.

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.

Avoiding Septic Shock: How Climate Change can cause Septic System Failure and Whether New England States are Prepared

February 2017

This white paper discusses climate change impacts on septic systems in New England, and whether states in the region are prepared for these impacts. The paper provides a state-by-state analysis of septic system regulations in New England and discusses how these regulatory frameworks are not fully considering climate change impacts, especially groundwater table rise. It also identifies challenges in septic system regulation, and suggests recommendations and best practices for how states and municipalities can work to change laws, amend rules, or adopt new policies or incentives to better construct, manage, and regulate septic systems to be resilient to climate change.

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.

New Hampshire Coastal Viewer

2015

The New Hampshire Coastal Viewer is an online mapping tool with coastal resources spatial data, hazards-related spatial data, and other spatial data sets for New Hampshire's 42 coastal watershed communities. Launched in 2015, this tool provides users the ability to access more than 150 spatial data sets, and to make and share their own customized maps.

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.
