Abstract
Level II scour evaluations follow a process in which hydrologic, hydraulic, and sedient-transport data are evaluated to calculate the depth of scour that may result when given discharge is routed through a bridge opening. the results of the modified Levell II analysis for structure I-70-104-5128 on Interstate 70 crossing Brandywine Creek in Hancock County, Indiana, are presented. The site is near the town of Greenfield in the central part of Hancock 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 6.5 feet for the modeled discharge of 6,900 cubic feet per second and approximately 8.0 feet for the modeled discharge of 9,140 cubic feet per second.
