Brantas River

River in East Java in Indonesia

The Brantas is the longest river in East Java, Indonesia.[2] It has a length of 320 km,[3] and drains an area of over 11,000 km2 from the southern slope of Mount Kawi-Kelud-Butak, Mount Wilis, and the northern slopes of Mount Liman-Limas, Mount Welirang, and Mount Anjasmoro.[4] Its course is semi-circular or spiral in shape: at its source, the river heads southeast, but gradually curves south, then southwest, west, then north, and finally it flows generally eastward at the point where it branches off to become the Kalimas and Porong River.

History

Shallow Brantas river near Kediri.

King Mpu Sindok moved his kingdom from the Mataram Kingdom in Central Java to a new location on this river at circa 950 A.D. Possibly (only one of several reasons given) due to a Mount Merapi volcanic eruption, he had to leave his kingdom to this new safe place near the present city of Madiun.
