Post-project appraisals in river restoration-case studies of Love River in Kaohsiung and Kao-Shan Creek in Taichung

Restoration of rivers and streams has attracted increased interest in recent years. In Taiwan, there are no consistent definitions and lacks adaptive management of river restoration. Therefore, this study clarified the definition of river restoration first and then used an evaluation tool, Post-Project Appraisals (PPAs), to evaluate two restoration projects. One is the urban river restoration project of Love River in Kaohsiung, and the other is the dam removal project in Taichung. The results showed that integrated documents could help us to evaluate restoration project well i.e. the check dams removal of Kao-Shan Creek. In the restoration of Love River at the Heart of Love Rive, the lake of pre-project baseline survey caused the bad design of ecological ponds setting and the objective of water quality improve was failed. There have no integrated documents, it's difficult to draw some improve suggestion, nor adaptive management.
