Merapi�s eruption which occurred on October 26th 2010 had disadvantageous impact for human life that live surrounds it. The primary disaster was Pyroclastic cloud that smashed villages surround it. In addition, the secondary disaster continuously became a threat for human life around the rivers that disgorge at Mount. Merapi. One of the secondary disasters is Putih River�s material overflowing into Yogyakarta-Magelang Highway. The series of Sabo dam which had been built along the river could not handle that phenomenon. Sabo dam was built and expected to accommodate volcanic material, or at least to resist the velocity of volcanic material (sediment controlling), so the damage that caused by the flow became relatively small. However this function could not work at that phenomenon. In order to know the function of sediment controlling of Sabo dam in Putih River, it is necessary to study the performance of Sabo dam. This research used Kanako software ver. 2.04 and reviewed Sabo dam PU-D1 Mranggen and PU-C8 Ngaglik. There were four simulated scenarios in this research: a scenario without Sabo dam
