Preliminary Assessment of Channel Stability and Bed-Material Transport along Hunter Creek, Southwestern Oregon (el. knyga) (skaityta knyga) | knygos.lt
Atsiliepimai
Aprašymas
This report summarizes a reconnaissancelevel assessment of channel condition and bedmaterial transport relevant to the permitting of instream gravel extraction in Hunter Creek, a coastal stream draining to the Pacific Ocean south of Gold Beach, Oregon (fig. 1, next page). The assessment is based on a review of existing datasets (such as bridge-inspection surveys, watershed analyses, and gravel-extraction records), repeat delineation of bar and channel features from aerial photographs, and field observations and particle-size measurements made during July 2010. Findings from these multiple datasets and observations were used to (1) assess the vertical stability of the Hunter Creek channel and identify locations where the channel may be incising, aggrading, or stable and (2) identify key datasets and issues that are relevant to understanding channel condition, bed-material transport, and potential effects of instream gravel extraction on Hunter Creek.
