FEMA project - Franklin and Orleans counties in Vermont

For the Franklin and Orleans Counties Risk MAP project, the USGS New England Water Science Center will develop new analyses of flood risk throughout both counties and will produce updated flood insurance rate maps (FIRMs) for all communities in the counties.

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-...

Development of Regional Regression Equations to Estimate the Magnitude of Peak Flows for Selected Annual-Exceedance Probabilities in Maine

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. The flood-frequency characteristics for streamgages and regression equations for estimating flood magnitudes at ungaged sites were last developed in 1999 (Hodgkins, 1999).

EPA National Low Flows

Low streamflow has great ecological importance as it defines the minimum extent (and carrying capacity) of in-stream habitat and affects biota composition and distribution, and species trophic structure.
