Natural Channel Design Difficulties When Confronted with Anthropogenic Downstream Fining in a Sand-Pebble Channel
Publication: World Environmental and Water Resource Congress 2006: Examining the Confluence of Environmental and Water Concerns
Abstract
Natural downstream fining of gravel channels to sand channels occurs by several mechanisms in many rivers and streams. This condition presents several extreme difficulties when natural channel design is proposed in a reach where this fining occurs. However, when this fining occurs by man-induced changes in a stream channel, there are no clear methods for accounting for such artificial boundary conditions. This paper discusses the use of at-a-station hydraulic geometry analysis in a sand-pebble channel for used in a remediation design at Pope Air Force Base in North Carolina. The failure of the original natural channel design at this location was discussed in a paper presented at the 2004 EWRI World Water Congress in Salt Lake City. The proposed remediation sand bed channel design will be discussed in this paper.
