Ian Armstrong is a Hydrologist in the New England Water Science Center.
Ian's academic research involved quantifying normal fault evolution from river profile analysis in Southwest Montana. His passion for studying rivers continues at the USGS, where he is primarily involved in hydraulic modeling for flood risk assessment studies throughout New England. Ian's work also includes estimating domestic water use for Rhode Island and optimizing stream crossing designs across Massachusetts.
Science and Products
Stream Flood Vulnerability Assessment at Acadia National Park
The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with Acadia National Park, is assessing the vulnerability of the park’s streams, culverts, and bridges to flood damage and erosion using design flows for selected high streamflow recurrence intervals to inform management decisions on infrastructure upgrades.
A Statewide Hydraulic Modeling Tool for Stream Crossing Projects in Massachusetts
The U.S. Geological Survey (USGS) and the University of Massachusetts at Amherst (UMass Amherst), in cooperation with the Massachusetts Department of Environmental Protection (MassDEP), began a series of studies in 2019 to develop a GIS-based hydraulic modeling tool and to provide preliminary culvert designs for stream-crossing replacement projects in Massachusetts on USGS StreamStats.
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.
