Paul Misut

Environmental engineer and scientist with over thirty years of government experience in the field of hydrology. 



My work is to plan, direct, and assist in all aspects of design and implementation of groundwater and geochemical projects.  I instruct employees in methods of water data collection and analysis, provide technical advice and guidance on analysis methods and tools.  I present information to the public and scientists through meetings and conferences. I provide technical reviews for other professionals.

My primary collaborators are within the USGS , U.S. Navy, U.S. EPA, New York State Department of Environmental Protection, and New York City Department of Environmental Protection.  My typical role in research teams is as a team member

The theme of my research program has become groundwater flow modeling.  The major theme of my research program is modeling of the Long Island, New York region.  Millions depend on Long Island aquifers for drinking water and use its receiving water bodies.  In addition to the need to understand system function with respect to questions such as how much water is available, problems include contamination from human activities at the landsurface, and saltwater intrusion from excessive pumping and/or sea level rise.  Throughout my career, I have advanced the understanding of the Long Island system as a whole and at specific locations through application and development of emerging techniques. In my assignments, I am typically responsible for those project portions that I am lead author of reports about, so please see my bibliography.  My report topics include application of transitional probability-based geostatistics, density-dependent flow modeling, climate change scenario modeling, design of remediation systems, delineations of contributing areas, and coupling of groundwater flow models with geochemical models. For the last decade, I have been lead author on all district groundwater flow modeling projects and  model project components treating Long Island, New York.

A minor theme of my research is groundwater flow modeling of regions beyond Long Island, and groundwater modeling generally.  My main report topics  beyond Long Island are subterranean mine flooding and development of web interfaces to display three dimensional transient state model simulations.

I have worked to transfer my knowledge to the public through development of graphical user interfaces and helped to shape USGS methods for dissemination of modeling data releases. I have advocated for and assisted in the development of the USGS GUI Modelmuse and related codes.

My recent research accomplishments include novel transitional probability methods to represent aquifer heterogeneity in the  main water supply aquifer of Long Island, and high density particle tracking simulations to delineate contributing area of unprecedented smoothness (>greater than 10 million particles simulated simultaneously).

J. Outreach and Media Coverage

I have shown consistency and longevity in promoting groundwater modeling technologies aimed to facillitate the usage of groundwater models by the general public.  1996, I created a web site to display animations of the transient response of a three-dimensional groundwater- flow model, described in an abstract of the USGS National Computer Technology Meeting.  By 2009, I  coathoured a USGS professional which included a website that served animations of transient model simulations.   At these early dates, websites of model animations were forward-looking contribution with leadship and societal implications, paving the way for expanding media types for USGS dissemination.
