Abstract -- Typhoons frequently take place in Taiwan yearly, which cause a lot of disasters and property losses. According to meteorological history, the number of occurrence of typhoons and heavy rainfalls in 2001 is at most in the records. Base on the database of Water Resource Agency, there were 17 heavy rainfalls and 8 typhoons in 2001, which the main cause of serious damages and property losses in Taiwan. The purposes of the project are data collections and hazard records, including meteorological, hydrological, and climatic data, and damages and property loss due to typhoons and heavy rainfalls; besides, documentations of hazard prevention, dealing with emergency, recovery from disasters of central and local governments are also recorded and collected in the project. The study will give ideas for basin management and planning, and hazard prevention scheme in the near future.
Two tasks were executed in the project, firstly meteorological and hydrological data were collected and analyzed. The data are used for rainfall distribution diagrams, hydrographs, and etc; secondly, for coordination with the project ‘Establishment of systematic model for flood damage evaluation’, data damage or property loss are collected, which include national tax, data from sampling survey, insurance compensation, and etc. Besides, data of flood damage occurrences in Tainan Science-Based Industrial Park and Tainan Technology Industrial Park were also collected. Except for this study report, another report is written for telling about the stories of typhoons and heavy rainfalls in 2001.
There are 6 chapters in the report, in Chapter 1, objectives and tasks are defined. The details are elaborated in Chapter 2, which includes data format definition and working processes planning. Analyses of flood data are carried out in Chapter 3, which shows flood damage events collections, and comparisons of collected data and flood potential, the study from National Science & Technology Program for Hazard Mitigation. Hydrological analyses are carried out in Chapter 4, which include basin descriptions, rainfall distributions, rainfall contour diagrams, and hydrographs. Descriptions of field investigation, analyses of filed data and sampling survey are given in Chapter 5. Also, documentations of insurance compensation of flood damage, and data collection of Tainan Science-Based Industrial Park and Tainan Technology Industrial Park are presented in Chapter 5. Finally, conclusions and suggestions are given in Chapter 6.
Data mining is important not only for academic researches, but also engineering applications. For example, the field data can be provided for parameter calibrations of ‘Systematic Model for Flood Damage Evaluation’ to enhance the reliabilities of the model. Here, the study strongly suggests the data mining should be practice continuously in the future. At last, the project team would like to say thanks to all that helped us to finish the project.
