The Tabalong River (Indonesian: Sungai Tabalong; Banjar: Batang Tabalong) is a river traversing Tabalong Regency, in the province of South Kalimantan, Indonesia.[1][2] The river flows into the Negara River. It is a confluence of two tributaries: the Left Tabalong and Right Tabalong rivers.
The river flows in the southeast area of Borneo island with predominantly tropical rainforest climate (designated as Af in the Köppen-Geiger climate classification).[5] The annual average temperature in the area is 24°C. The warmest month is June, when the average temperature is around 26°C, and the coldest is January, at 22°C.[4] The average annual rainfall is 2982mm. The wettest month is December, with an average of 392mm rainfall, and the driest is September, with 101mm rainfall.[6]
Use
The Tabalong River provides a large swamp land, which can be used to grow rice during the dry season. However, during the wet season, the discharge of the river and its tributaries increases so high, that it often threatened the harvest and caused flooding in the nearby villages.[7][8] Therefore, the local government builds flood gates to control the flow and prevent floods.[9]
The abundance of water during the wet season is actually useful to fill up the pools for fishery.[10]
