Oblique photography of measured channel cross-sections from left and right bank monuments from 2007-08-15 to 2009-10-07 (NCEI Accession 0152489)

We are collecting stream channel geometry and bed sediment grain size distribution data at Sedgeunkedunk stream to evaluate physical habitat changes associated with the Brewer Dam removal. These data complement studies led by others that are investigating biological responses to the project. Together, the physical and biological data collected in the lower Sedgeunkedunk stream help us understand the effectiveness of dam removal for restoring diadromous fish access and ecosystem recovery.

本研究团队于塞奇孔达克溪（Sedgeunkedunk Stream）采集河道几何形态与河床沉积物粒度分布数据，以评估布鲁尔大坝（Brewer Dam）拆除所引发的栖息地物理变化。该数据集可补充其他团队针对该项目开展的生物响应相关研究。通过整合在塞奇孔达克溪下游采集的物理与生物数据，我们能够明晰大坝拆除在恢复洄游性鱼类通行及促进生态系统恢复方面的实际成效。
