Estimating the sizes of flood events is critical for flood risk management and other activities. We used data from several sources in a statistical analysis of flood sizes for rivers in the Philippines. Flood size is mainly controlled by the size of the river catchment, along with the volume of rainfall. Other factors, such as land use, appear to play only minor roles in flood size. The results can be used to estimate flood size for any river in the country, alongside other local information.
