Summary: | Riverbank failure is a geological phenomenon that occurs when the soil or rock comprising the
bank of a river collapses, leading to the rapid erosion of land and the formation of large cracks
and sinkholes. While it is a natural occurrence, riverbank failure can have severe consequences
for nearby communities and the environment. A massive riverbank failure occurred along the
Kelantan River in Kampung Pohon Celagi, Pasir Mas, Kelantan, Malaysia. In this study, the
affected area of the riverbank failure was determined and the effects of the bank failure on the
village socio-economics and community were investigated. This study utilized interview methods
and field observations to collect data and information. The study shows that 0.58 km3 land in the
village was affected by the riverbank failure. The local authorities designated the 50-m range from
the riverside as the red zone where most houses and buildings collapsed with the riverbank
movement, and the parameters were 51–100 m is the high-risk area, 101–150 m is moderate, and
≥ 151 m upwards is low risk area, respectively, from the riverbank. The affected communities were
required to move to safer areas and leave their properties to be demolished or failure with the
riverbank. Socioeconomically, businesses around the disaster area were affected as they were
prohibited from operating in the high-risk area. Overall, the disaster resulted in the local
communities losing their property and experiencing depression. As a result, it is expected that all
stakeholders will work together to develop a solution that ensures the well-being and safety of the
community from riverbank failure. |
