Physical Forces Impacting the Hudson River Shoreline

The Hudson’s shorelines are subject to a wide variety of complex and interacting physical stresses, including ship wakes, wind-driven waves, ice, storm surge, and currents. These have not been systematically measured or characterized throughout the Hudson.

These forces exert pressure and movement of the soil, resulting in erosion of the shoreline. In order to implement an effective shoreline stabilization method, it is important to take into account the level of stressors (wakes, currents, ice, etc.) occurring at any location.

Stevens Institute of Technology has advanced our understanding of these forces through a combination of historic studies, direct measurements, and modeling of current and wind wave energy. This work advances our understanding of present conditions that shoreline protection will need to withstand.

Geospatial Data

There are a variety of geospatial tools which can help shoreline stakeholders assess the conditions on their shoreline.


NYS Clearinghouse – Hudson River Estuary Data and Maps

The NYSDEC Hudson River Estuary Program in collaboration with numerous partners has supported the mapping of biologic, chemical, and physical characteristics of the Hudson River Estuary.


New York Harbor Observing and Prediction System (NYHOPS)

Provides meteorological and oceanographic conditions both in real-time and forecasted out to 72 hours in the Hudson River, the East River, NY/NJ Estuary, Raritan Bay, Long Island Sound and the coastal waters of New Jersey. Graphic images are available of water level; surface and bottom temperature; surface and bottom salinity; surface and bottom currents; NOAA winds; coastal waves – height, period and direction; CDOM (Chromophoric Dissolved Organic Matter).

Tivoli Bays Launch Closure – 2020

The canoe and kayak launch on the Kidd Lane access road at Tivoli Bays WMA is closed for renovations until further notice. At this time, DEC does not have an estimated completion date for the project. Please contact Nathan Ermer at 845-256-3047 for more information about this project. Thank you for your patience and understanding.
