Michal Niemoczynski

A hydrologist with the USGS New Jersey Water Science Center working with the Surface Water Investigations Program (SWIP) and is primarily involved in the realm of surface water data collection, analysis, and dissemination.

Michal Niemoczynski is a hydrologist with the New Jersey Water Science Center. Michal graduated Summa Cum Laude from East Stroudsburg University in 2008 with a Bachelor of Science Degree in Environmental Science with Geography Minor. He began his career in 2009 in New Jersey as a hydrologic technician within the NJWSC’s Hydrologic Data Assessment Program, operating surface-water field trips in the northeastern and southern areas of the state, as well as operating NJWSC’s bridge scour network in coordination with the New Jersey Department of Transportation. From 2011-2014 he helped build, maintain, and analyze tidal estuary gages that utilized hydroacoustic technology to compute streamflow that was subsequently, used in the construction of a hydrodynamic flow model of the Barnegat Bay within Ocean County, NJ. He has assisted with coastal and inland storm-response efforts in multiple states and serves as the NJWSC’s storm tide monitoring program coordinator. He maintains a thorough knowledge of surface-water indirect measurement techniques and hydraulic modeling using HEC-RAS 1D and 2D. He employed RAS creating several libraries of flood-inundation maps for the flood-prone northeastern areas of New Jersey from 2012-2015. More recently, he has been working with projects publishing coastal flood inundation map libraries for NJWSC’s network of 25 tide telemetry gages based on ADCIRC modeled coastal storm data and simultaneously wrapping up a cooperative project with New York Department of Environmental Conservation developing a comprehensive water quality model for the Mohawk River basin based on a 129-mile-long HEC-RAS unsteady hydraulic model. Currently, he is working on a project evaluating streambed roughness characteristics and coefficients in New Jersey streams and developing HEC-HMS models that will be used to inform a rural road-closure network in Hunterdon County, New Jersey. Michal is also a certified MOCC/MOICC instructor with the USGS watercraft safety program and holds his United States Coast Guard Master’s License.

Professional Experience

  • Lead for New Jersey’s Surge, Wave, and Tide Hydrodynamics (SWaTH) network.

  • He is involved with a coastal flood inundation mapping initiative for the New Jersey Tide Telemetry Network that will develop a series of flood inundation maps based on ADCIRC modeled coastal storm data correlated to USGS tide gages.

  • He is part of a team working on a cooperative project with New York Department of Environmental Conservation (NYDEC) developing a comprehensive water quality model for the Mohawk River basin based on a complex unsteady hydraulic model.

  • He has worked extensively on the construction and operation of ADVM flow monitoring gages on the Barnegat Bay estuary in New Jersey.

Education and Certifications

  • Graduated Summa Cum Laude from East Stroudsburg University in 2008 with a Bachelor’s of Science Degree in Environmental Science with Geography Minor.

  • Certified MOCC/MOICC instructor with the USGS Watercraft Safety Program.

  • United States Coast Guard Masters 25 GRT (Gross Register Tons) License.

Manning's Roughness Coefficient for New Jersey Streams

Manning’s Roughness Coefficient (n) is an input to the Manning’s Equation, which can be used for the computation of streamflow during times it is impractical or impossible to make a measurement. ​ Methods and regional equations for determining the value of n have largely been developed in the western United States; New Jersey is comparatively unstudied. New Jersey features a diverse range of...

Vertical Profiles and Near Surface Water Quality Transects for Dissolved Oxygen Monitoring of the Arthur Kill, New York and New Jersey, September 7th and 8th, 2023

Transects of near-surface continuous water-quality data and vertical profiles of the same parameters were collected over a 24-hour period from September 7 to September 8, 2023 in the Arthur Kill. The Arthur Kill is a tidal strait located between Staten Island, New York, and Union and Middlesex Counties, New Jersey, and connects Newark Bay to the north and Raritan Bay to the south.
