The study site is located in the confluence of Dahan Creek and Sindian Creek and therefore conducted into severe deposition problems. The obvious reclamation trend based on the sediment deposition behavior and bad water quality make this area as an inferior habitat for aquatic organisms although it has been claimed as protected area for water birds. This area is so-called Hwa-Chien Nature Park. We addressed two methods to succeed the implementation: one is to use tidal creek creation to establish diverse habitat types and increase the hydraulic retention time (HRT). Another strategy is to exercise a solar-induced aeration system to raise dissolved oxygen of water column. The investigation and monitoring project will be built up as well to observe the hydraulic, morphologic characteristics and water quality parameters, such as bathymetry, water surface elevation, flow velocity, DO, BOD5 and so on. Meanwhile habitat improvement techniques of estuary wetland, environment data bank, tidal creek relevant theories or (and) empirical formulas, schemes of solar-induced aeration system will be developed in this study. In addition, we’ll also present “the SOP of construction and management of Dahan Sindien estuary wetland”. Due to the innovation and creation of the combination of several topics and aspects, the outcomes of this study can contribute to not only government authority practices but also advanced academic research in the coming future.感潮溼地河相溶氧潮溝太陽能動力系統estuary wetlandgeomorphologytidal creekdissolved oxygen (DO)solar-induced aeration system
