Simulation of Water-Surface Elevations for a Hypothetical 100-Year Peak Flow inBirch Creek at the Idaho National Engineering and Environmental Laboratory, Idaho

摘要

Th purpose of this study was to delineate the areal extent of possible floodingat the INEEL resulting from peak flow in Birch Creek having a recurrence interval of 100 years. This report presents the results of phases two and three and includes a discussion of the effects of State Highway 22, the culvert under State Highway 22, a tributary channel to Birch Creek, and diversion channels on streamflow. Geomorphic characteristics of gravel pits and Birch Creek Playa, ultimate sumps for high flows also are described.
