摘要：The study examined return period analysis as a tool for flood prediction in urban areas. This
technique enables us to know when an event is expected to occur, be equaled, or be exceeded.
When floods occur, the effects are always very devastating, sometimes resulting in destruction
of homes, villages, human life and property. Urban floods in most cases result from unplanned,
uncoordinated urbanization projects, poor sanitary habits of dumping of refuse, and poorly
maintained and insufficient drainage. These are well highlighted in this study. Results indicate
that for thirty years of data, the return period is 10.3 years for a maximum 1-month rainfall
of 804 mm with a maximum 1-year rainfall of 2,544 mm for same return period. The study
recommends routing through specific drainages in flood prone areas of Port Harcourt to
mitigate the impacts of flooding
