Natural Phenomena Hazards Modeling Project: Flood Hazard Models for Department of Energy Sites

摘要

For eight sites, the evaluation of flood hazards was considered in two steps. First, a screening assessment was performed to determine whether flood hazards may impact DOE operations. The screening analysis consisted of a preliminary flood hazard assessment that provides an initial estimate of the site design basis. The second step involves a review of the vulnerability of on-site facilities by the site manager; based on the results of the preliminary flood hazard assessment and a review of site operations, the manager can decide whether flood hazards should be considered a part of the design basis. The scope of the preliminary flood hazard analysis was restricted to evaluating the flood hazards that may exist in proximity to a site. The analysis does not involve an assessment of the potential of encroachment of flooding at specific on-site locations. Furthermore, the screening analysis does not consider localized flooding at a site due to precipitation (i.e., local run-off, storm sewer capacity, roof drainage). These issues were reserved for consideration by the DOE site manager. 9 refs., 18 figs. (ERA citation 13:049572)
