Water Hazards

Floods and droughts can have long-term impacts on communities. The New England Water Science Center develops tools to estimate flood extent; partners with FEMA to develop products to support the Risk Mapping, Assessment, and Planning program; and generates information to better understand water-resource sustainability during periods of prolonged drought and in response to climate change.

Remembering Tropical Storm Irene in New England

On August 28, 2011 Tropical Storm Irene made landfall in New England, leading to coastal storm surge, significant riverine flooding, sediment transport to Long Island Sound, and major infrastructure damage and destruction. Ten years later, the USGS New England Water Science Center looks back at Irene, the data collected by our Center during the event, the response by our employees before, during...

New England Drought, 2020

Below average and infrequent rainfall from May through September 2020 led to an extreme hydrologic drought across much of New England, with some areas experiencing a flash (quick-onset) drought.

New England Drought Information

Droughts are one of the most expensive and damaging hydrologic hazards in the United States. They are generally slow in developing, frequently occur over a long period of time, and can affect large areas and populations.

Geospatial Dataset of Wells and Attributes in the New England Groundwater Level Network, 2017

The drought of 2016 affected hydrologic conditions throughout New England. Responses of USGS groundwater observation wells to this event, however, were not uniform and were sometimes markedly different from site to site. Although USGS scientists were able to provide explanations for most of these situations, the event highlighted the need for additional well information to develop quantitative and...

Flow Modeling at Dam Removal Sites Associated with Hurricane Sandy Resiliency Efforts

The purpose of this work is to better understand the effects of dam removal on local hydraulics, fish passage, and flooding. This study is part of a larger effort to monitor ecological resilience changes at nine Hurricane Sandy coastal resiliency aquatic connectivity restoration projects. It will contribute crucial knowledge that will be used to improve aquatic connectivity system cost...

Development of Regional Regression Equations in Connecticut

Knowledge of the magnitude and frequency of floods is needed for the effective and safe design of bridges, culverts, and other structures. This information is also important for flood-plain planning and management. Periodic examination of flood-frequency characteristics is essential to ensure the best estimates of flood magnitudes for a given annual exceedance probabilities (AEP).
