It is defined as the greatest depth of precipitation for a given duration meteorologically possible for a design watershed or a given storm area, at a particular location and at a particular time of the year, with no allowance made for long-term climatic trends. PMP estimates are used in designing infrastructure such as dams, levees, and flood control systems to ensure they can withstand the most severe weather events and catastrophic flooding likely to occur in a given region. Procedures for estimating the PMP cannot be standardized; they vary with the amount and quality of data available, the basin size and location, the regional topography and orographic effects, the storm types producing extreme precipitation, and the climate. This volume is a companion to the Technical Note Enhancing the Safety and Resilience of Dams in the Context of Climate Change and Extreme Hydrological Events (World Bank 2025). Part I provides the detailed methodologies of climate change impact assessment and Part II provides case studies from different regions on impact assessment and adaptative reservoir operation.en-USCC BY-NC 3.0 IGOCLIMATE ACTIONCLIMATE CHANGEDAM SAFETY ASSURANCEINFRASTRUCTURE REGULATIONSAFETY OF DOWNSTREAM COMMUNITIESDAM RISK CLASSIFICATIONReportWorld Bank
