Reviewing the Impact of Earthquakes on Flood Occurrence: Insights from Kota Belud, Sabah, Malaysia

Abstract

This study investigates the trends and processes of flooding in Kota Belud, Sabah, Malaysia, following the 2015 Ranau Earthquake. The earthquake caused landslides that altered river systems and significantly impacted flood patterns. Using an interdisciplinary methodology, we examined geological processes, river morphology, sediment dynamics, and erosion mechanisms to understand the correlation between geological forces and flooding. The investigation spanned a decade (2010-2020), revealing an increase in flood incidents post-earthquake. Key findings include the impact of sediment dynamics on river behavior, the role of river morphology, and the importance of erosion and sedimentation in flood timing. This research offers valuable insights into disaster management strategies, emphasizing the need for understanding geological influences on flood susceptibility.
