Environmental streamflows in the United States: historical patterns and predictions

The term environmental streamflows refers to the magnitude, frequency, seasonal timing, duration, and rate of change of streamflows needed to sustain freshwater and estuary ecosystems and human wellbeing. It is important that environmental streamflow assessments by water managers consider changes in climate, land use, and water management; this cannot be done effectively without understanding...

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...

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).

IJC Lake Champlain and the Richelieu River Project

The record setting floods of 2011 in Lake Champlain Vermont/New York U.S. and the Richelieu River in the province of Quebec Canada prompted the U.S. and Canadian governments to work together to identify how flood forecasting, preparedness and mitigation can be improved in the Lake Champlain-Richelieu River (LCRR) basin.
