Quantifying on Safety Index of Flood Hazard Mitigation and its Application in Urban Area
In recent years, the continuous increasing global temperature has caused the sea level to rise, changes in precipitation, and consequently, the Earths climate substantially altered. Intergovernmental Panel on Climate Change (IPCC) of United Nations pointed out that global warming would be more detrimental in Asian countries: the land would become much dryer, floods would occur more frequently, tropical cyclones and typhoons would be much stronger, and not to mention that the frequency of extreme whether conditions such as typhoons, droughts and floods will be much higher than ever. In Taiwan, however, there is no integrated assessment on hazard potential for various types of areas or on building safety. Neither local governments nor community residents have any idea about how safe their area is when attacked by different types of hazards or the hazard potentials. In this study, the researchers took typhoons as an example to analyze the structure in safety index of flood hazard mitigation, and the weight of the parameters. They then used the result to establish the rating of weighted safety index and an assessment method. Next, six buildings from different location and of different type from the demonstration area (Luzhou District, New Taipei City, Taiwan) were selected for computing the safety index of flood hazards mitigation. The results suggested that when comparing buildings from a same area but with different building conditions, conditions of the building would affect the score of the safety indicator under the same external conditions. On the other hand, when comparing buildings with same building conditions, flood potential data of the external environment would be an important factor affecting the safety index.
