USGS Hudson River Watershed Suspended-Sediment Monitoring Network Active

By New York Water Science Center December 1, 2016

Suspended-Sediment Monitoring Network

Cohoes Falls during Tropical Storm Irene 2011

The USGS NY Water Science Center maintains a network of near-real-time sensors to monitor the movement of suspended sediment into and through the freshwater reach of the tidal Hudson River. Information from this network helps quantify the movement of sediment in the watershed to assist resource managers and stakeholders reduce dredging costs, target resources to mitigate soil loss, and modify land use practices and behavior that result in sediment-related damage to the ecosystem.

Sediment transport due to extreme events: The Hudson River estuary after tropical storms Irene and Lee

Tropical Storms Irene and Lee in 2011 produced intense precipitation and flooding in the U.S. Northeast, including the Hudson River watershed. Sediment input to the Hudson River was approximately 2.7 megaton, about 5 times the long-term annual average. Rather than the common assumption that sediment is predominantly trapped in the estuary, observations and model results indicate that approximat

Suspended sediment transport in the freshwater reach of the Hudson river estuary in eastern New York

Deposition of Hudson River sediment into New York Harbor interferes with navigation lanes and requires continuous dredging. Sediment dynamics at the Hudson estuary turbidity maximum (ETM) have received considerable study, but delivery of sediment to the ETM through the freshwater reach of the estuary has received relatively little attention and few direct measurements. An acoustic Doppler current

Use of an ADCP to compute suspended-sediment discharge in the tidal Hudson River, New York

Acoustic Doppler current profilers (ADCPs) can provide data needed for computation of suspended-sediment discharge in complex river systems, such as tidal rivers, in which conventional methods of collecting time-series data on suspended-sediment concentration (SSC) and water discharge are not feasible. Although ADCPs are not designed to measure SSC, ADCP data can be used as a surrogate under certa
