Amphibious urbanization as a sustainable flood mitigation strategy in South-East Asia

Appling amphibious urbanization is a new smart and sustainable flood mitigation strategy for floodplain area in South-East Asia. The objective of this study is to evaluate the technological and environmental aspects of the amphibious house as a sustainable flood mitigation strategy in South-East Asia. The technological and environmental aspects are investigated under sustainability. The point load test and drag force estimation and interviews are conducted. Amphibious urbanization is completely aligned with the technological aspects of a safe living conditions during flood rush. This system identified as one of the green and most sustainable new strategies in South-East Asia.

Drag coefficient for amphibious house

Abstract Recently, flooding has become a serious issue and disaster in Malaysia. Therefore, it is crucial to search for a more effective flood mitigation approach in Malaysia. Amphibious house system is a new sustainable and flexible flood mitigation measure within a floating urbanization environment. Amphibious house has been designed based on buoyancy terminology by using precast and fast formulatable concrete components such as concrete pontoons. These pontoons are made of green lightweight concrete and analysed for buoyancy and stability against vertical and horizontal loads. This study aims to identify the precise force calculation from floods to amphibious houses as a new flood mitigation system. The objective of this study is to develop a new equation for calculating the drag coefficient for the amphibious house. A new experimental method is used to calculate drag force on the amphibious house in 1/25 scaled-down floodplain model. As a result, the new equation is developed for the drag coefficient. The sensitivity analysis shows the accuracy of this research.
