The 2016-2020 collaborative research project Dams and Sediment in the Hudson (DaSH) collected sediment cores from impoundments on tributaries of the Hudson River and tidal wetland complexes within the Hudson River estuary. These data are publicly available and archived at University of Massachusetts – Amherst Scholarworks. The project combined field observations with an analysis of sediment transport to better understand how sediment released by dam removal in the Lower Hudson River watershed will affect the estuary. To learn more about the project’s results, see the team’s Summary of DaSH Project Findings.
About these datasets
This project generated three related datasets. The dataset description describes these data, sampling methods and locations, and model inputs and methods.
- Lower Hudson Watershed Dam Impoundments Sediment Data
Sediment core data collected during 2017-2018 from 17 dam impoundments located on tributaries to the tidal portion of the Hudson River. Data archive: https://doi.org/10.7275/xktv-8m12
2. Hudson River Estuary Tidal Marsh Sediment Data
Sediment core data collected from six tidal wetland complexes located within the Hudson River estuary. Data archive: https://doi.org/10.7275/dh3v-0x33
3. Hudson River Estuary Model Simulations of Dam Sediment Releases
Model outputs from simulations of dam removal scenarios, generated using a hydrodynamic and sediment transport model for the Lower Hudson River. Data access: Data files are large (32 GB/file, 60 files per case) and cannot be served remotely at this time. Data are available by contacting David Ralston, email@example.com.
