Flood-prone areas
The total flood-prone area in Taiwan is about 1,150 km2 with 80% located in land subsidence regions or regions that have not finished improvement projects for river systems, drainage systems, or sea dikes; especially at coastal districts, villages, and townships of Yilan, Taipei, Changhua, Yunlin, Chiayi, Tainan, and Kaohsiung.

Project principles

  • The planning, design, and construction stages of the projects shall comply with ecological conservation principles to reduce their impacts on the ecological environment.
  • Planning and design works shall observe the safety standards and suit the local circumstances. Moreover, they shall meet the integrated water regualtion concepts and the overall basin management principles for holistic management at upstream, midstream, and downstream regions.
  • Planning and design of hydraulic structures should be compatible with the local landscape, environment, and building structures to avoid visual obstruction.
  • Planning and design should incorporate local cultural elements and tourist attractions to create a distinctive environment. New business opportunities would be created through the development of local culture and tourism industry.
