A Case Study of the Temporal and Spatial Distribution of River Hydraulics and Habitat in the Wu-chi river, Taiwan
نویسندگان
چکیده
Based on the premise of flood management, administration of rivers in Taiwan consists of building many water structures to protect the lives and properties of people. But the ecological equilibrium of the area may possibly be damaged. Thus, how to maintain the ecological instream flow and how to lessen the negative impact of human development on river ecology are topics that have to be further investigated. The relationships between hydraulic conditions and ecological habitats are discussed and compared with quantified assessment technology in this study. Acrossocheilus paradoxus was selected as the target species, and a hydraulic model HESRAS 3.0 along with the habitat model RHABSIM 2.2 was employed to estimate the ecological instream flow of the habitat. The Wu-chi river in Taiwan was chosen for the case study.
