Modified level II streambed-scour analysis for structure I-465-139-5260 crossing Fishback Creek in Boone County, Indiana
Year: 1997
Type: report
Abstract: Level II scour evaluations follow a process in which hydrologic, hydraulic, and sedimenttransport data are evaluated to calculate the depth of scour that may result when a given discharge is routed through a bridge opening.The results of the modified Level II analysis for structure 1-465-139-5260 on Interstate 465 crossing Fishback Creek in Boone County, Indiana, are presented.The site is near the town of Zionsville in the southeastern part of Boone County.Scour depths were computed with the Water Surface PROfile model, version V050196, which incorporates the scour-calculation procedures outlined in Hydraulic Engineering Circular No. 18.Total scour depths at the piers were approximately 13.5 feet for the modeled discharge of 5,600 cubic feet per second and approximately 16.9 feet for the modeled discharge of 7,600 cubic feet per second.
