Chao Phraya River

The Chao Phraya River is the major river in Thailand, flowing through the low alluvial plain that forms the center of the country. It begins at the confluence of the Ping and Nan rivers in Nakhon Sawan province and flows south for 372 kilometers to the Gulf of Thailand. The river played a crucial role in the development of ancient civilizations, including the Mon kingdom and the Ayutthaya Kingdom, and has been modified by human engineering since the Ayutthaya period. The river is an important transportation route and has numerous bridges and canals, with major settlements including Bangkok, Ayutthaya, and Samut Prakan.learn more on wikipedia
