The principal tributaries of the Chao Phraya River of Thailand are the Pa Sak River, the Sakae Krang River, the Nan River (along with its principal confluent the Yom River), the Ping River (with its principal confluent the Wang River), and the Tha Chin River. [1] Each of these tributaries (and the Chao Phraya itself) is further tributed by additional minor tributaries often referred to as khwae. All of the tributaries, including the lesser khwae, form an extensive tree-like pattern, with branches flowing through nearly every province in central and northern Thailand. [1] None of the tributaries of the Chao Phraya extend beyond the nation's borders. [2] The Nan and the Yom River flow nearly parallel from Phitsanulok to Chumsaeng in the north of Nakhon Sawan province. The Wang River enters the Ping River near Sam Ngao district in Tak province.
The following is a tree demonstrating the points at which the major tributaries of the Chao Phraya River branch off from the main river and from each other. [1]
