| Abstract: | The increasing natural disasters, especially floods during the last quarter century, are raising the economic losses in Taiwan.
The most severe hazard in Taiwan is flooding induced by typhoons and storms in summer and autumn. By comparing the rivers
around the world, the ones in Taiwan have the steepest slopes, the largest discharge per unit drainage area, and the shortest
time of concentrations. Rapid urbanization without proper land uses managements usually worsen the flood problems. Consequently,
flood hazards mitigation has become the most essential task for Taiwan to deal with. Although the government keeps improving
flood defense structures, the flood damage grows continuously. In this article, possible flood mitigation strategies are identified
for coping with complex environmental and social decisions with flood risk involved. |
