Geomorphology monitoring sites at 15 locations along the Roanoke River in Salem and Roanoke, Virginia, represented riffle or pool habitats and were designed to facilitate repeated measuring at the same cross section over time. Local bench marks were installed at each site to provide both horizontal and vertical control. At a minimum, each site had two bench marks (designated BM) and two transect control marks (designated TC) that were tied together through a static survey-grade Global Positioning System (GPS) survey to establish control to the nearest centimeter. Annual cross-section topographic surveys were conducted during summer low-flow periods at the 15 geomorphology monitoring sites using a total station from 2005 to 2012 at [...]

Annual surveys were conducted as part of a U.S. Fish and Wildlife mandated monitoring program associated with construction activities being conducted by U.S. Army Corps of Engineers (USACE). Sites were designated as “control” or “construction” to discern between sites upstream of the Roanoke River Flood Reduction Project (RRFRP) conducted by USACE, and therefore unaffected by construction activities, and sites within the construction reach. Cross-section surveys and slopes were used to classify sites into geomorphological categories for general interpretation and regional context. Bankfull and base flow channel dimensions such as mean depth, width, and cross-sectional area were calculated to evaluate channel stability and change over time.
