“…Instead of trying to silence, excommunicate and punish, let's look at the other side and try to listen, engage and, when we must, disagree." 25 If we need to be convinced to seek out facts and insights we might not already know or affirm, there is plenty of empirical research showing how often people make faulty judgments on the basis of incomplete information. The flawed decision-making that can accompany overconfidence has been exhibited by clinical psychologists making diagnoses and football executives choosing the top draft picks.…”

The most devastating flood event in Kota Bharu was recorded in December 2014, which affected several properties worth millions of dollars and thousands of homes. Damage to physical properties, especially buildings, is identified as a significant contributor to flood disasters in Malaysia. Therefore, it is essential to address physical flood vulnerability by developing an integrated approach for modeling buildings’ flood vulnerability to decrease the flood consequences. This study aims at developing a flood vulnerability assessment approach using an indicator-based model (IBM) for individual buildings in Kota Bahru, Kelantan, Malaysia. An intensive literature review and expert opinions were used to determine suitable indicators that contribute to the physical flood vulnerability of buildings. The indicators were grouped into three components, i.e., flood hazard intensity (I), building characteristics (C), and effect of the surrounding environment (E). The indicators were further refined based on expert opinions and Relative Importance Index (RII) analysis. Based on their contribution to the Malaysia local building flood vulnerability, priority weight is assigned by the experts to each of the selected indicators using the participatory Analytical Hierarchy Process (AHP). A spatial database of buildings in Kota Bharu is developed through field surveys and manually digitizing building footprints from satellite imageries. The identified indicators and their weight are added to each building footprint. The Weighted Linear Combination (WLC) aggregation method combined the weight of indicators into a vulnerability index and maps. The results of a physical flood vulnerability were validated using building damage information obtained through interviews with the community that experienced previous flood in the study area. The result showed that about 98% of the study area’s buildings have either moderate or low vulnerability to flooding. The flood vulnerability map has an overall accuracy of 75.12% and 0.63 kappa statistics. In conclusion, the IBM approach has been used successfully to develop a physical flood vulnerability for buildings in Kota Bharu. The model contributes to support different structural and non-structural approaches in the flood mitigations process.

“…Conversely, the scenarios are different in the state of Pahang which the affected areas are usually rural areas and floods cover vast stretches of land. Therefore, the damage suffered can still be high even though the value of properties is lower (Zakaria et al, 2017). The steady growth of industries in Pahang likes transportation and petrochemical sectors have led to a comparably rapid growth of urbanization (Shakir et al, 2015) This urban development with building of roads and buildings consequently led to fewer stretches of land covered by vegetation, which is an important factor causing rapid river flow (Chan, 1997 ;Gupta, 2010).…”

Every year, thousands of people in Malaysia have to be moved out and be relinquished from their homes due to heavy rainfall and poor irrigation system that led to a flood situation especially on monsoon season. Thus, the current study aims to concentrate on the two central aspects of disaster management in the context of flood disaster management in Kuantan, Pahang by the means of a mixed-method approach. The effectiveness of communication mechanisms in the case of floods is assessed with quantitative analysis using descriptive design. On another note, this study also takes a closer look at the underlying logistical framework found in flood disaster contexts and identifies its critical success factors via a qualitative research technique. Using thematic analysis, in-depth semi-structured interviews are analysed to arrive at conclusions regarding the critical success factors. Findings on the effectiveness of disaster communication indicated that the communication between authorities, agencies, non-government organizations and flood victims are still in need of improvement particularly related to emergency updates and increasing community awareness on the right actions for upcoming floods. The study also proved that coordination, communication, knowledge, and preparedness are the critical success factors for humanitarian response in the case of flood management. It is vital to protect the communities from flood disaster; hence, a clear and precise standard operating procedure needs to be in place and must be integrated among all related agencies which will benefit the stakeholders.
