Ciliwung

Ci Liwung is a 119 km long river in the northwestern region of Java where it flows through two provinces, West Java and the special region of Jakarta. The natural estuary of the Ciliwung river, known as the Kali Besar, was an important strategic point for trade in the precolonial and colonial periods and was instrumental in the founding of the port city of Jakarta, but has been lost from reorganization of the watercourse of the rivers around the area into canals.EtymologyThe etymology of Ciliwung is uncertain; the two least implausible assumptions are "the whirlpool" or "the meandering one" . It is possible that the name originated from one of the many epithets of the king of Pajajaran Sri Baduga Maharaja, among them is Prabu Haliwung, so named because of his temperamental attitude. The name Ci Haliwung was recorded in the map of C.M. Pleyte .GeographyCi Liwung is 119 km long with a catchment area of 476 km2. The Ciliwung river has its source at Mandalawangi in Bogor Regency with the highest peak at 3,002 m. The river flows in a northern direction passing several active volcanoes, Mount Salak, Mount Kendeng, and Mount Halimun, crosses two main cities Bogor and Jakarta before finally flowing into the Java Sea through Jakarta Bay. The main tributaries in the upper catchment area are the Ciesek and Ciluar rivers with respective lengths 9.7 km and 21.0 km, with catchment areas of 27.15 km2 and 35.25 km2 respectively.
