  <dc:description>&lt;p&gt;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-674-7-6974 on Interstate 164 crossing Schlensker Ditch in Vanderburgh County, Indiana, are presented. The site is near the town of Daylight&amp;nbsp; in the northwestern part of Vanderburgh 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 176 feet for the modeled discharge of 2,100&amp;nbsp; cubic feet per second and approximately 33.4 feet for the modeled discharge of 2,940 cubic feet per second.&lt;/p&gt;</dc:description>
