To pursue sustainable water resources development, rationality and integrity is essential for water resources planning. The Taiwan Ecohydrology Indicator System (TEIS) is an important guiding reference for sustainable water resources management, which confines water resources development to environmental load for maintaining sustainable development principles. In river systems, river flow, water quality and suspended sediment are closely related to each other, and thus play important roles in river ecosystems. For making an effective and comprehensive strategy for sustainable water resources management, this study will first explore the complex impacts of river flow, water quality and suspended sediment on the river ecosystem of the Tanshui River, which has long-term observational data, and then investigate the effects of extreme events on this river ecosystem. This study will use both statistical methods and clustering analysis coupled with advanced artificial intelligence techniques to investigate the complex impacts of river flow, water quality and suspended sediment on fish diversity of the Tanshui River basin. The fuzzy logic theorem combined with the advanced multi-objective optimization method are applied to searching the optimal reservoir operational strategy for solving the complex issues related to water resources management. Consequently, the river ecosystem of the Tanshui River basin can be improved and the multi-objective water resources management of Taiwan can be enhanced. Our previous studies have related river flow to fish diversity and effectively identified the influences of the river flow characteristics on fish communities in Taiwan. For making a more comprehensive planning on sustainable water resources management, it is required to take the environmental factors of rive ecosystems into a thorough consideration. Therefore, this study will explore the impacts of river flow, water quality and suspended sediment on fish communities in a more comprehensive and integrative manner and provide water managers with valuable research results as a guiding reference for planning sustainable water resources management. Our research team has long-term endeavored to explore the ecohydrology in Taiwan based on our professional research techniques and abundant analytical experiences. As the PI of this project, Distinguished Professor Fi-John Chang has made outstanding professional achievements on ecohydorology and water resources management. Professor Li-Chiu Chang, the Co-PI, is an excellent expert in artificial intelligence and reservoir operation optimization. For making a more comprehensive, profound and interdisciplinary investigation on the environmental issues relevant to fish diversity, we have invited Professor Edwin E. Herricks from the University of Illinois at Urbana-Champaign in USA and Associate Professor Chih-Hao Hsieh from National Taiwan University to join our research team as professional consultants on fish ecology. Their ample experiences in data analysis can enrich the execution of this project. Regarding river water quality and suspended sediment, we have invited Dr. Shang-Shu Shih from National Taiwan University to conduct the simulation analyses of river sediment transport, fluviatile facies and ecological habitats. We expect to comprehensively control all the requirements of this study and provide water authorities with interdisciplinary value-added results as a consulting and guiding reference for sustainable water resources management.生態水文類神經網路台灣生態水文指標系統淡水河流域魚類族群多目標水庫操作EcohydrologyArtificial Neural Network (ANN)Taiwan Ecohydrology Indicator System (TEIS)River BasinFish CommunitiesMulti-Objective Resevoir Operation
