Phnom Penh is in the south-central region of Cambodia, and is fully surrounded by Kandal Province. The municipality is on the banks of the Tonlé Sap, Mekong, and Bassac Rivers. These rivers provide freshwater and other natural resources to the city. Phnom Penh and the surrounding areas consist of a typical flood plain area for Cambodia. Although Phnom Penh is at  above the river, monsoon season flooding is a problem, and the river sometimes overflows its banks.
