Hidrology
editCi Buni is the main river in the Cibuni River system, covering a total area of 1,435 km2 (554 sq mi) across three regencies, including Cianjur, Bandung, and Sukabumi . The upper part of the Cibuni Basin is adjacent to the upper part of the Citarum Basin in the north, where the flow of the Citarum River goes northward in Java and flows into the Java Sea. Meanwhile, the Cibuni Basin directs its stream southward and flows into the Indian Ocean.[7]
The upstream is located in Rancabali of Bandung Regency, then it flows in the southwest direction to Pasirkuda, Tanggeung, Kadupandak, and Agrabinta (all in Cianjur Regency) then turns to the southeast passing Sindangbarang, Cianjur at the south coast of Java.[8] The main tributaries of Ci Buni are:
- Cijampang
- Cilumut
- Cibangoah
- Cidolog
- Cikarang
- Cibalapulang
With the high rainfall between 2239 mm to 5579 mm, the river has high debit and a large watershed area for the population to be the source of drinking water, irrigation, and washing.[8] Along the stream is a topical forest with diverse plants, fish, birds, boars, apes, wild cats, and reptiles.[9] Closer to the ocean, the river mouth widens to almost 200 m and hosts sweet water crocodiles.[9]
