Gardner Bent is a Hydrologist in the new England Water Science Center.
Gardner is currently the Surface-Water Specialist for the New England Water Science Center and has been in this position since 2015. Prior to this he served as the Massachusetts-Rhode Island Data Chief, overseeing surface-water, groundwater, and water-quality data collection, from 2006-2011. During 2012-14 and prior to 2006 he served as a project hydrologist on a number of mainly surface-water related studies in Massachusetts and Rhode Island. The studies have involved state-wide equations for estimating streamflow statistics and bankfull channel geometry, sediment transport assessments, flood-related studies, and watershed assessments. He has been at the USGS since 1989.

Total water level data from the January and March 2018 nor’easters for coastal areas of New England
During winter 2017–18 coastal areas of New England were impacted by the January 4, and March 2–4, 2018, nor’easters. The U.S. Geological Survey (USGS), under an interagency agreement with the Federal Emergency Management Agency (FEMA), collected total water level data (the combination of tide, storm surge, wave runup and setup, and freshwater input) using the North American Vertical Datum of 1988AuthorsGardner C.

The Mississippi Delta, located in northwest Mississippi, is an area dense with industrial-level agriculture sustained by groundwater-dependent irrigation supplied by the Mississippi River Valley Alluvial aquifer (alluvial aquifer). The Delta provides agricultural commodities across the United States and around the world. Observed declines in groundwater altitudes and streamflow contemporaneous witAuthorsCourtney D.

Because coastal areas in Connecticut, Rhode Island, and Massachusetts were heavily affected by Hurricane Sandy in October 2012, the U.S. Geological Survey (USGS), under a mission agreement with the Federal Emergency Management Agency, collected storm tide high-water marks in those coastal areas. This effort was undertaken to better understand the areal extent and impact of storm tides resulting frAuthorsLance J. Ostiguy, Timothy C. Sargent, Brittney Izbicki, Gardner C.

The U.S. Geological Survey, in cooperation with the Massachusetts Department of Recreation and Conservation, Office of Water Resources, began a study in 2019 to update the regional regression equations for estimating selected low-flow statistics at ungaged sites in Massachusetts.New England Flood Information
The USGS delivers continuous streamflow, stage (water-level), and tide data to help emergency managers and other decision makers protect life and property caused by floods and other water-related hazards.New England Drought, 2020
Below average and infrequent rainfall from May through September 2020 led to an extreme hydrologic drought across much of New England, with some areas experiencing a flash (quick-onset) drought.New England Drought Information
Droughts are one of the most expensive and damaging hydrologic hazards in the United States. They are generally slow in developing, frequently occur over a long period of time, and can affect large areas and populations. - Data
