Abstract
Most of flood-damage mitigation measures administrated by the government in recent years emphasized often on common engineering approaches. With a retrospect on flood protection experiences in Taiwan and in some other countries, however, relying simply on the engineering approaches like flood detention dam, protection embankment and river cutoff, would not be the complete solution against flood disasters. It would be more efficient to reduce the loss from floods if engineering approach and non-engineering approach work synergistically.
Yen-Shui Creek and Kee-Lung River basins were chosen as the pilot areas for the integrated flood damage mitigation project. In fact, the flood hazard control over the two basins is urgent, and the two basins are different in several ways. The main differences are, respectively, meteorological and hydrological characteristics, histories of development, and factors causing a flood. Yen-Shui Creek is an agricultural plain at a low degree of development, with various giant projects under planning or establishment; on the other hand, Kee-Lung River is a narrow valley of highly developed, with some river reaches insufficient to protect the flood. The diverse natures of the two basins will make the results suitable to be applied to other basins.
This three-year project is carried out by ten professors specializing in hydraulic engineering and hydrology from the National Taiwan University and the National Cheng-Kung University. The alms are: (1) the establishment of the latest and basic database for the existing flood protection constructions, (2) the improvements for the drainage system as well as the meteorological and hydrological monitoring system, (3) the evaluation of the scenario simulation of several inundation cases caused by different rainfall events by taking the rainfall, runoff and hydraulic models in series, and (4) the establishment of an evaluation model for flood damages, and a proper measure of the benefits of mitigation to the flood disaster. With the combination of the basic database for flood protection and the inundation scenario simulation, a decision support system can be set up consequently. The research is prospective to reduce flood damages when non-engineering approaches work successfully with the existing flood control structures, and the non-engineering approach can also be supplemental to the shortcoming of engineering approaches.
