Add to FacebookThe US Army Alaska completed the construction of a unique bank restoration project along Ship Creek on Fort Richardson near Anchorage, Alaska in October, 2003. The project employs the use of both vegetative treatments plus large stones to deflect the main flow in the creek away from the bank and toward a center bar. The project is designed to result in erosion of the center bar, providing adequate flow area while further protecting the restored bank. Since construction, two events have tested the protection. In October, 2003 a water supply reservoir upstream was dredged, with 25,000 yards of material placed over the dam to pass down Ship Creek. Design flows have also occurred in late October, 2003 and during the summer 2004. This paper describes the changes that have occurred since the installation of the project. GPS surveys have monitored the banklines and positions of the stone deflectors, while bed sampling and velocity measurements have kept track of changes in the hydraulic regime.
