Lower Hudson River Sediment Flux Project

In cooperation with The New York State Department of Environmental Conservation's Division of Water and Hudson River Estuary Program

Purpose

The Hudson River is a significant source of suspended sediment to New York Harbor where millions of dollars are spent annually maintaining navigation channels and disposing of dredged sediment. Understanding the amount of suspended sediment moving through the Hudson and the timing and mechanisms associated with that movement is a first step in reducing the need for and cost of dredging operations.

Goals

1. To quantify the mass transport (flux) of suspended sediment moving through the freshwater reach of the tidal Hudson River.
2. To provide suspended sediment and river discharge data to the public in near-real time.
3. To better understand the mechanisms responsible for sediment transport in the tidal river.

Project Data

All real time and daily data are now being served by NWISweb. Graphs and data for each parameter from the last 60 days can be displayed or downloaded. Daily values for select parameters can be displayed or downloaded dating back to March 2002.

• Near real-time ADCP derived suspended-sediment data (NWISweb)
• Near real-time ADCP derived velocity and discharge data (NWISweb)
• Near real-time environmental data (NWISweb)
• Near real-time velocity profile data (text)
• Daily values (NWIS Web) (March 2002 - present)
• View an animation of ADCP dervived velocity and backscatter at the study site.
