Scoping of flood hazard mapping needs for Coos County, New Hampshire Scoping of flood hazard mapping needs for Coos County, New Hampshire
This report was prepared by the U.S. Geological Survey (USGS) New Hampshire/ Vermont Water Science Center for scoping of flood-hazard mapping needs for Coos County, New Hampshire, under Federal Emergency Management Agency (FEMA) Inter-Agency agreement Number HSFE01-05X-0018. One of the priorities for FEMA, Region 1, is to develop updated Digital Flood Insurance Rate Maps (DFIRMs) and...

Flood Study of Warren Brook in Alstead and Cold River in Alstead, Langdon, and Walpole, New Hampshire, 2005 Flood Study of Warren Brook in Alstead and Cold River in Alstead, Langdon, and Walpole, New Hampshire, 2005
This report presents water-surface elevations and profiles as determined using the U.S. Army Corps of Engineers (USACE) one-dimensional Hydrologic Engineering Center River Analysis System, also known as HEC-RAS. Steady flow water-surface profiles were developed for two stream reaches: the Cold River from its confluence with the Connecticut River in Walpole, through Alstead to the...

The New Hampshire watershed tool: a geographic information system tool to estimate streamflow statistics and ground-water-recharge rates The New Hampshire watershed tool: a geographic information system tool to estimate streamflow statistics and ground-water-recharge rates
Estimates of low-flow statistics, flow durations, and ground-water-recharge rates are needed to assist water-resource managers in assessing surface-water resources and ground-water availability. Often these estimates are required at ungaged sites where no observed streamflow data are available for analysis. Regression equations for estimating low-flow statistics and flow durations, and...

Generalized estimates from streamflow data of annual and seasonal ground-water-recharge rates for drainage basins in New Hampshire Generalized estimates from streamflow data of annual and seasonal ground-water-recharge rates for drainage basins in New Hampshire
This report presents regression equations to estimate generalized annual and seasonal ground-water-recharge rates in drainage basins in New Hampshire. The ultimate source of water for a ground-water withdrawal is aquifer recharge from a combination of precipitation on the aquifer, ground-water flow from upland basin areas, and infiltration from streambeds to the aquifer. An assessment of...

Development of regression equations to estimate flow durations and low-flow-frequency statistics in New Hampshire streams Development of regression equations to estimate flow durations and low-flow-frequency statistics in New Hampshire streams
Regression equations and basin-characteristic digital datasets were developed to help water-resource managers estimate surface-water resources during periods of low flow in New Hampshire. The regression equations were developed to estimate statistics for the seasonal and annual low-flow-frequency and seasonal period-of-record and period-of-record flow durations. Because streamflow is...

A stream-gaging network analysis for the 7-day, 10-year annual low flow in New Hampshire streams A stream-gaging network analysis for the 7-day, 10-year annual low flow in New Hampshire streams
The 7-day, 10-year (7Q10) low-flow-frequency statistic is a widely used measure of surface-water availability in New Hampshire. Regression equations and basin-characteristic digital data sets were developed to help water-resource managers determine surface-water resources during periods of low flow in New Hampshire streams. These regression equations and data sets were developed to...
