Abstract
Regional flood frequency analysis (RFFA) is essentially a data-based approach that attempts to substitute space for time to enable design flood estimation at sites with little or no recorded flood data. An RFFA method consists of three principal steps: (1) data preparation, (2) formation of regions, and (3) development of regional estimation models. This chapter intends to provide a theoretical understanding of various RFFA techniques to researchers and practicing hydrologists. We have attempted to cover essential aspects of RFFA, which include (1) data requirements, (2) selection of probability distributions, (3) formation of regions, (4) various forms of regional estimation equations, (5) validation of RFFA models, (6) RFFA in arid regions, and (7) impact of climate change on RFFA. We would like to acknowledge the anonymous reviewers for making constructive comments and suggestions, which have improved the materials presented in this chapter. We would also like to acknowledge the members of our family for supporting us in writing this chapter.
