Title: Larkin Mill Dam bed sediment particle diameter from 2008-06-09 to 2016-03-30 (NCEI Accession 0152462)
Abstract: We are collecting stream channel geometry and bed sediment grain size distribution data at the Parker River to evaluate physical habitat changes associated with the planned Larkin Mill Dam removal. In addition to evaluating channel response to dam removal, our two years of pre-removal data collection (2008 and 2010) bracketed a large flood event that allowed us to investigate whether this small dam is an efficient sediment trap. Our analyses suggest that sediments readily move over the dam during storm events and other flows, and we hypothesize that, aside from a thin active surface layer where erosion and deposition regularly occurs, the small quantity of stored sediments are relatively stable. The primary data are in a PDF document with ancillary information in CSV and PDF format.
