Flood- and drought-related natural hazards activities of the U.S. Geological Survey in New England

March 23, 2016

The U.S. Geological Survey (USGS) has many ongoing and recent water-related natural hazard activities in New England that can be used to help mitigate the effects of natural hazards in cooperation with other agencies. The themes related to potential hazards and the tools and science to better understand and address them include the following:

Erosion and landslides
• Fluvial erosion (sediment transport, bridge scour, and bankfull channel geometry characterization)
• Current and historic landslide mapping

Flood documentation and assessment
• Flood high-water marks
• Flood modeling and frequency analysis
• Flood inundation mapping
• Peak-flow regression equations

Drought documentation and assessment
• Drought frequency analysis
• Low-flow frequency and flow duration statistics
• Water use and availability during drought

Hydrologic monitoring
• Streamflow monitoring network
• Groundwater monitoring network
• Tidal monitoring network
• Snow surveys and ice jam monitoring

Tools for natural hazard assessment and mitigation
• Light detection and ranging (lidar) remote sensing technology
• StreamStats Web-based tool for streamflow statistics
• Flood inundation mapper
