Modeling of individual debris flows based on DEMNAS using Flow-R: A case study in Sigi, Central Sulawesi

Abstract: On 2018 September 28, 18:03 a local time (10:03 am UTC), the Mw 7.5 earthquake with a focal depth of about 20 km devastated the Palu region in Central Sulawesi, Indonesia resulting in a catastrophic disaster and many casualties. The Palu earthquakes triggered widespread landslides upstream, contributing to the sizeable material volume accumulated in rivers and mountain slopes. After the Palu earthquake, from September 28, 2018, until December 2021, at least 24 events of debris floods have occurred, which have … Show more

“…Since low-resolution data were used, the modified Holmgren algorithm [42] was used in this study. Putra et al [53] stated that they also chose this algorithm because it is less sensitive to the DEM resolution. The SFLM is the second key part of the propagation stage.…”

“…The Mw 7.5 'supershear' earthquake attacked Palu-Central Sulawesi and its surroundings on 28 September 2018 [1], causing a catastrophic disaster [2]. The earthquake was associated with massive tsunami and liquefaction [1], and it triggered landslides and debris flows [2], [3] in seventy-seven hilly areas in Palu, Donggala, and Sigi [3]. This study focused on landslide study, especially in landslide susceptibility mapping (LSM).…”
