Abstract
The purpose of this project is to propose the analysis flowchart of design
defence scope of inundation disaster. Two pilot study areas were chosen as the
study cases to check the performance of analysis flowchart of design defence
scope of inundation disaster. The achievements of this project will help the
cooperation teams of NCDR to carry out the defence scope of inundation
disaster for local governments in future. The defence scope of inundation
disaster can be applied in the Local Disaster Prevention & Response Plans of
local governments for four periods of disaster cycle such as mitigation,
preparedess, response and recovery.
According to analysis and simulation preocesses, four steps for determining
the design defence scope of inundation disaster of local governments are given
below,
(1) scenario simulation of inundation potential.
(2) establishment of the relationship between inundation depth and damage loss
for varied land-use.
(3) risk analysis of inundation disaster damage.
(4) suggestion of the procedure of design defence scope for inundation disaster.
Taipei and Tainan counties/cities were selected as the pilot areas of case
study for this project. The social-economic indices, history records of inundation
areas, special land-use types, the density degree of population, damage losses of
inundation disaster, protect standard of river and the annual budget of protect
and reduction with the total loss of different return periods were analysed and
compared to draft the design defence scope of inundation disaster for pilot areas.
Finally, the study suggests that the design defence scope standard of inundation
disaster is 200-year return period for Taipei county/city and 100-year return
period for Tainan county/city respectively. Owing to the significant industrial
III
products and resources for Taiwan, the design defence scope standard of Tainan Science Park in Tainan county should be raised to 200-year return period.
