Modified level II streambed-scour analysis for structure I-65-81-5523 crossing Big Blue River in Shelby 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 1-65-81-5523 on Interstate 65 crossing Big Blue River in Shelby County, Indiana, are presented.The site is near the town of Mt.Auburn in the southwestern part of Shelby 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 30.8 feet for the modeled discharge of 23,900 cubic feet per second and approximately 35.7 feet for the modeled discharge of 31,300 cubic feet per second.
