Geography

Phnom Penh is located in the south-central region of Cambodia, and is fully surrounded by the Kandal Province. The municipality is situated 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 situated at 11.89 metres (39 ft) above the river, monsoon season flooding is a problem, and the river sometimes overflows its banks.
