Within last 10 years, high intensity of rainfall had triggered the increase of water level during floods along Sub-watershed of Muara Bangkahulu River, Bengkulu, Indonesia. The high rainfall intensity was caused by extreme weather change. This study was focused on a segment of Muara Bangkahulu Sub-watershed called Semarang Segment. This segment is one of socio-economy centres in Bengkulu City. This study was initiated by performing the environmental investigation and collecting the rainfall intensity data in the study area. The site investigation data and soil tests were also performed to obtain the soil properties along sloping ground of sub-watershed. The analysis to obtain the maximum flood discharge as well as the maximum water level within 10 years was conducted. Furthermore, the slope stability analysis using both finite element and limit equilibrium methods was performed. In general, the results of this study could be a recommendation to stakeholders to consider the future impact in the study area. The results of this study could also bring a recommendation for the slope protection in the study area.
