Ecological engineering methods for torrent management in Taiwan

A successful ecological engineering method require a design methodology for coordination with ecological principles. For recent years, Taiwan is attempting to employ different methods for torrent management, taking local ecological environments and aquatic habitats into account. As shown in many cases, some stone pavement methods have enabled ecological conservation, but resulted in serious erosions after a rainy season or typhoon season. Therefore, torrent management requires fully realizing torrent characteristics, making strict assessment, and coordinating the best construction methods with ecological concepts in establishment of near-nature ecological engineering methods applicable to Taiwan's rivers and streams.
