The purpose of this chapter of the Guidelines is to provide technical guidance for determining the appropriate Inflow Design Flood (IDF) to be used in the review of spillway and appurtenant structure designs and to conform to the provisions of the Federal Guidelines for Dam Safety.
This chapter is not intended to provide a complete manual of all procedures used for estimating inflow design floods for spillways, because the selection of procedures is dependent upon available hydrologic data and individual watershed characteristics. All studies submitted to the Commission should be performed by a competent engineer experienced in hydrology and hydraulics, and should contain a summary of the design assumptions, design analyses, and methodologies used to evaluate the inflow design flood.
