Christopher L Gazoorian is a Hydrologist at the New York Water Science Center.
Chris Gazoorian currently serves as the Surface Water Specialist for the USGS New York Water Science Center. Prior to this, he served as a Hydrologist, leading studies and field data collection relating to surface-water, groundwater and water-quality. Chris' research interests include innovative use of non-contact sensors, ice-jam flood monitoring, and streamflow uncertainly and statistical analysis.
As a Hydrologists at U.S. Geological Survey, the New York Water Science Center
- Estimation of unaltered daily streamflow at rural ungagged locations
- Streamflow statistics and trends
- Ice Jam monitoring and modeling in the Mohawk River, Schenectady, NY
- Computation of peak streamflow in open channels and through control structures by direct and indirect methods
- Flood documentation and flood frequency trends
- Develop streamflow ratings for stage-discharge and index-velocity relations.
As a Student Hydrologist at U.S. Geological Survey, New York Water Science Center
- Assisted with multiple research projects investigating biogeochemical nutrient cycles, acid deposition and water.
- Analyzed soil and water properties including total C and N using a Carlo Erba EA 1110 elemental analyzer.
- Reported data for publication in scientific journals and USGS reports.
- Developed the NY WSC Standard Operating Procedure manuals for soil analyses.
- Instructed students on analyses procedures and tracked progress to meet deadlines.
- Collected water, soil, sediment and biological samples and maintained field sites.
As a Graduate Research Assistant at State University of New York at Albany, Department of Geography and Planning
- Conducted soil analyses on archived and new samples to identify centennial scale changes in soil C in a Russian steppe.

Methods for Estimation Flood Magnitude and Frequency at Ungaged Streams in New York, excluding Long Island
Summary: Extreme flooding can threaten life and property in flood-prone areas, as well as cause damage to critical infrastructure along roadways and canals. The effective management of these areas, and appropriate design of structures along rivers and streams, relies on understanding the magnitude and frequency of floods at gaged locations, and the ability to estimate these data at...
Next Generation Water Observing System: Delaware River Basin
The Next Generation Water Observing System (NGWOS) supports water availability assessments, management, and prediction by enhancing water observations in basins that represent major U.S. hydrologic regions. The Delaware River Basin was the first Integrated Water Science basin selected, providing an opportunity to implement the NGWOS program in a nationally important, complex interstate river...
An Analysis of Trends in the Magnitude of Floods in Urbanized Watersheds on Long Island, New York
Summary: This study aims to do a thorough analysis of trends in peak streamflows on Long Island. Reliable information about the magnitude and frequency of floods is essential for flood insurance studies, flood-plain management, and the design of transportation and water-conveyance infrastructure, such as roads, bridges, culverts, dams, and levees. Federal, State, regional, and local...
Lake Ontario Flood Monitoring and Mapping
Problem– Lake Ontario experienced period-of-record (1918-2017) maximum monthly average water levels during May through July 2017. NOAA lake gages recorded instantaneous peaks-of record, 249.2 at Olcott, 249.1 at Rochester, and 249.0 at Oswego and St. Vincent. These high water levels along with wind-generated waves caused flooding of thousands of residences and businesses and the erosion...
Monthly Hydrologic Conditions for New York
The U.S. Geological Survey New York Water Science Center’s monthly summary reports and tables of hydrologic conditions for surface and ground water list the station, county, period of record, and several statistics, including color-coded percent exceedance* categories based on average monthly conditions for the period of record at each station.
