The U.S. Geological Survey (USGS) New England Water Science Center worked with the Federal Emergency Management Agency to document the floods of January 4, 2018 and March 2-4, 2018, in coastal Massachusetts. USGS conducted a frequency analysis of stillwater elevations at three National Oceanic and Atmospheric Administration coastal gages following the coastal floods of 2018. The data for these analyses for gages in Boston, Massachusetts, Portland, Maine, and Seavey Island, Maine are included in the child item "Data to Support Stillwater Analyses." Stillwater elevations recorded in January 2018 in Boston (9.66 feet in the North American Vertical Datum of 1988, NAVD88) had an annual exceedance probability (AEP)...

Data layers in this child item include high-water mark and storm-sensor data collected by the U.S. Geological Survey (USGS) New England Water Science Center following the January 4, 2018, and March 2-4, 2018, winter-storm events in New England. High-water marks and continuous water-level sensor data range from Portland, Maine, to Provincetown, Massachusetts, and reference the North American Vertical Datum of 1988 (NAVD88). For more information about these storm events and the data collection, please see Bent, G.C., and Taylor, N.J., 2020, Total water level data from the January and March 2018 nor’easters for coastal areas of New England: U.S. Geological Survey Scientific Investigations Report 2020–5048, 47 p.,...

The input datasets are daily precipitation and minimum and maximum temperature for a period of 64 years for warming scenarios of 0 degrees to 8 degrees Celsius, by 0.5-degree increments for the Squannacook River watershed, which is a subwatershed of the Nashua River watershed in Massachusetts. The source of the data is the Stochastic Weather Generator (SWG; Steinschneider and Najibi, 2022) and includes 100 ensembles from the SWG. The daily time-series, space-delimited files cover three subwatersheds within the Squannacook River watershed in a format readable by the Precipitation Runoff-Modeling System (PRMS; https://www.usgs.gov/software/precipitation-runoff-modeling-system-prms). The input files were input to PRMS,...

The datasets are streamflow characteristics computed from the 1 million ensembles of the Stochastic Watershed Model for each warming scenario of 0 to 8 degrees Celsius in 0.5-degree intervals for the Squannacook River at West Groton, Massachusetts streamgage location. Each value in the files represents a streamflow characteristic computed from an ensemble that covers a period of 64 years of daily streamflows computed by the Stochastic Watershed Model. The Stochastic Watershed Model was developed at Tufts University (Shabestanipour and others, 2022). The streamflow characteristics include the 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence interval of the annual maximum daily streamflow and the 7-day low flow...

The U.S. Geological Survey New England Water Science Center, under an interagency agreement with the Federal Emergency Management Agency, conducted frequency analyses of stillwater elevations at three National Oceanic and Atmospheric Administration coast gages following the coastal floods of 2018. The datasets are comma-delimited files of period-of-record annual peak stillwater elevations collected at gages in Boston, Massachusetts, Portland, Maine, and Seavey Island, Maine, for analysis of annual-exceedence probabilities. The peak water-surface elevations are in feet in the North American Vertical Datum of 1988.
