摘要

Collapsed of Caldera-wall of Mt. Bawakaraeng occurred on March 26, 2004. The caldera is situated at elevation 2,600 m above MSL and is the headwaters of Jeneberang river. The volume of collapsed mass was estimated 200 ??? 3000 million M3 and it closed Jeneberang river channel along 7 km. One month after the collapsed, mud flow occurred and covered paddy field along the Jeneberang river. Up to now the mud flow frequently occurred, especially in the rainy season.udThe river discharge containing a high density of sediment has been flowing down into Bili-Biliudreservoir and it is anticipated that its lifetime would be shorter and the water quality of municipaludwater would be deteriorited.
