Retrofitting (Slip Lining) Culverts and Fish Passage-Phase II

项目名称：	Retrofitting (Slip Lining) Culverts and Fish Passage-Phase II
摘要：	Many culverts are approaching or are past their original design lives. These 'baby boomer' culverts will need to be repaired, rehabilitated, or replaced. Because entire replacement is so expensive and intrusive, alternate measures to extend the culvert project life are growing increasingly popular. One such method is slip lining, where a 'sleeve' is installed within an existing culvert barrel and stabilized. Plastic pipe sleeves are very popular for slip lining, but the reduced friction within the barrel can create a barrier to fish due to increased water velocities. Hence, mitigation of the increased velocities should go hand-in-hand with slip lined projects where fish passage (present or future) is to be considered. There has been very limited experience in providing for fish passage through slip lined culverts. This is a two-Phase project. Phase I, which includes a synthesis study and fieldwork, will be completed by Rollin Hotchkiss at Brigham Young University. This statement provides details of Phase II (laboratory and field evaluation of fish passage structures for slip-lined culverts), to be completed by Blake Tullis at Utah State University.
