July 2023 Flood in Vermont
From July 9 through July 12, 2023, 3 to 9 inches of rain fell within 48 hours across the state of Vermont, causing catastrophic flooding and millions of dollars in damage. The high amount of rain caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011.
Characterizing Future Flood Flows for Flood Insurance Studies
Current methods of flood-frequency analyses for flood insurance studies assume that the statistical distribution of data from past observations will continue unchanged in the future. This is known as the assumption of stationarity. This assumption allows scientists to estimate flood magnitude and frequency based on past records and the expectation that those estimates will represent current and...
Characterizing Future Climate and Hydrology in Massachusetts using Stochastic Modeling Methods
Communities across Massachusetts may face potential consequences of climate change, ranging from more extreme rainfall to more pronounced and frequent droughts. Climate change could alter the state’s hydrology in potentially complex and unanticipated ways. Typical approaches for projecting hydrologic risk under climate change can misrepresent and underestimate the variability of climate and...
Development of Flood Insurance Maps in New England
FEMA has requested USGS expertise in hydraulics, hydrology, and mapping to generate flood insurance maps for New England.
Development of Streamflow Record Extension Equations in New Hampshire
Currently, there are 16 designated rivers in New Hampshire in need of daily mean streamflow estimates for managing instream flows. Many of New Hampshire’s Designated Rivers have current and/or historical streamflow data that may be used to extend an existing streamgages streamflow record in time through record extension techniques. Evaluating the feasibility of record extension techniques to...
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...
