Continuous rain increasing in its intensity during the period since December 25, 2005 until January 1, 2006 in the Jember Regency of the East Java Province, Indonesia has caused several huge landslides in the upstream area of the Bedadung watershed. The heavy rainfall in the upstream area caused severe flooding and mudflows downstream along a stretch of 20km along the upstream rivers. The event took a toll of 98 human lives, destroyed hundreds of hectares of rice fields, and caused damage to hundreds of houses, particularly hit being the Manggis and the Glengseran villages. The railroad and National Road No.2 near Rambipuji city were also severely damaged causing a temporary breakdown of the transportation and lifeline systems along these arteries due to the landslides with flooding and mudflows. The significance of the occurrence of this huge natural disaster in the Jember Regency provides an opportunity to study such phenomena to anticipate the occurrence of such events in the future in Indonesia, and to prepare for the mitigation of their disastrous impacts. The authors have investigated the disaster-stricken areas, and the results of their study are elaborated upon in the present paper.
