Geography
editBa River's basin area makes up southern Phú Yên province, parts of Đắk Lắk province, around half of Gia Lai province and parts of Kon Tum province and therefore, much of the eastern part of the Central Highlands. Tributaries include Hinh River and Ayun River, among many others.[1]
The river's water volume varies significantly throughout the year, with only 47 and 45 m3/s in March and April and 366, 682, and 935 m3/s in September, October, and November.[1]
History
editRemains from different periods have been found along Ba River. They include a Sanskrit inscription from the fifth century at its mouth and various Champa sites, including the citadel Thanh Ho around 15 km inland.[2] The river certainly provided an important route far into the interior for the Cham people,[2] who were involved in trade with both their highland hinterlands and seagoing merchants.
