Thomas Suro
A hydrologist with the USGS New Jersey Water Science Center, with over 30 years’ experience working on projects in the areas of Surface-water hydrology and hydraulics. He is the Surface-Water Specialist (expert in field of surface-water) for the NJWSC and is the Project Chief for several ongoing projects related to flood frequency analysis and flood investigations topics.
Previously Chief of the Surface-water Investigations Program he managed a diverse group of scientists working on a wide range of surface-water related projects at the NJWSC. He also led large projects like the hydraulic and nutrient modeling project across upstate New York, and the coastal inundation mapping and analysis projects in New Jersey, as well as surface-water statistics and flood and damage impacts back to Hurricanes Irene, Sandy, and the Great Nor’easter of 1992.
Earlier, Tom also worked as the Assistant Chief of Hydraulic Surveillance and Investigations for the USGS NY: Troy; and Project Chief for Flood Investigations in New York.
Areas of interest:
- Surface-water hydraulics engineering and watershed modeling
- Flood frequency analysis and surface-water statistics
- Flood hydrology and hydraulics
- Inundation mapping
- Coastal Strom Surge Impacts, flooding and erosion
- Low-flow hydrology
- Estimating and modeling daily streamflow at ungaged sites to assist in water management and the development of streamflow standards.

Prepared a report, in cooperation with NYS-DOT, to document the maximum known stage and discharge of streams in New York (SIR 2014-5084).
Derived regression equations to estimate daily streamflow at ungaged sites in New York to assist in developing standards to protect aquatic habitats and natural ecosystems.
Pilot study to update low-flow statistics for several USGS gages and investigate changes in low-flow frequency statistics from 1976 to 2006 at selected streams in New York (SIR 2011-5112).
Managed the flood hardening of USGS gages in the Delaware River basin.
Project chief for projects in cooperation with FEMA and NYS-DOT to document floods along the Neversink River and Esopus Creek, and the Mohawk, Delaware, and Susquehanna River basins in New York during 2005 and 2006 (OFR 2006-1319, OFR 2007-1036, and OFR 2009-1063).
Published reports documenting the effects of, and worked as one of the crew chiefs on, projects to document the 2004 flood in the Upper Delaware River Basin of NY, and 1999 flood in southeastern New York.
Completed flood surveys to compute peak flood discharge by indirect methods
Worked on the Hudson River Salt-Front project (to model the location of the saltwater/freshwater junction), a hydraulic model to compute flow thru several large tainter gates and over a main spillway
Pioneered acoustic doppler current profiler (ADCP) use in eastern New York.
Managed the installation and calibration of an acoustic doppler velocity meter on the Hudson River.
Managed the documentation of flooding from the Great Nor’easter of 1992 along the New Jersey coast and published a report summarizing the results.
Worked on a flood warning project to provide real-time rainfall and river-level data in northern New Jersey to federal, state, and local officials for forecasting and public safety.
Worked on several projects including: water quality and groundwater data collection, groundwater aquifer tests, hydraulic modeling of lake outflows through automatic gates, and collecting low-flow surface-water data.
