Predictive simulation of concurrent debris flows: How slope failure locations affect predicted damage

Abstract: Predictive simulation of concurrent debris flows using only pre-disaster information has been difficult, partly because of problems faced in predicting debris-flow initiation locations (i.e., slope failure). However, because catchment topography has convergent characteristics with all channels in it joining each other as they flow downstream, damage to downstream areas could be predicted using relatively inaccurate initiation points. Based on this hypothesis, this study uses debris-flow initiation points gener… Show more

“…It is important to ensure that we are able to characterize the nature and driving forces responsible for flooding events. For example, papers in this issue highlight advances in knowledge on the role of groundwater rebound in urban environments for groundwater‐induced flooding of homes (Allocca et al, 2022), prediction capabilities for the location of slope failures to more accurately assess the impact of debris flow initiation on flood damage to downstream areas (Yamanoi et al, 2022), and alteration of flood frequency statistics due to extreme events for affected and near‐affected locations (Regier et al, 2022). It is critical for governing and regulation bodies to address the intensifying risk of flooding resulting from the increase in flood vulnerable areas due to climate change and urbanization (Pérez‐Morales et al, 2018) and for flood risk management to be incorporated directly into the urban planning process (Van Herk et al, 2011).…”
