Abstract
Taiwan, due to her geographic location, encounters many natural disasters such as earthquakes, typhoon, and flood, etc. every year. These hazards usually cause major loss of assets and casualties from the high density of population and intensive land usage. The government invests huge budget to mitigate the damage from the disasters. The investment of disaster mitigation should be proposition to the risk of the area so that adequate economical efficiency can be maintained. The risk assessment should base on a sound model for regional damage estimation. The estimation of regional flood damage involves a tremendous amount of data and most of them are spatially distributed such as population, traffic network, administration and land use zoning, building types and distribution, etc. This project is to implement the spatial database for regional flood damage estimation using Geographic Information System (GIS) as a spatial data management tool. The Basin of KeeLung River is chosen as pilot area for its high residential density and intense commercial and industrial activities.
Related data such as population, commercial and industrial activities, building type and distribution, digital terrain, dike and pumping stations, etc. were collected and integrated into a spatial database. Functions relating damages to inundation depth were established for different types of activities and land use. Regional flood damage can then be assessed spatially. The results from other related co-project such as inundation model were used for computation of the flooding risks. The results are useful for decision support for regional flood damage mitigation planning.
