In coastal Tainan, aquaculture had become prosperous for more than 200 years. But the local communities are facing some difficulties in the past decades. These include over-development, flooding, and unstable living quality. The built environment had changed a lot on the site. Developers keep filling soil to the fishponds and build more and more highrises for apartments or hotels. This also changes the relationship between humans and nature. The aquaculture industry is disappearing too. The culture is vanishing. To reserve and even renovate the culture of living with water, this thesis aimed to create a systematic method to build a water village for local fishermen, in relation to the aquaculture industry and flood prevention. In my research paper, I utilize the SWMM model, which is from the United States military system. It can help me modeling the existing drainage system. And also analyze the hydrograph of the selected area. For flood prevention, I turned some fish ponds into detention basins and constructed wetland, to create an additional flow that can reduce the pressure of the main drain line. By this, I can control the water in the detention basins and construct wetlands during disasters. And move it back to the main system afterward. For the circular flow, I try to explore the possibility that the schedule of aquacultural activities and the schedule of construction can integrate perfectly together. I proposed a three-year schedule that local farmers can build their own house while continuing their industrial activities. For all the material, I want it to be recycled or biobased as much as possible. For example, To deal with the overheating problem in summer. I design two layers of the roof which have different functions. The first layer is a bamboo roof, which can prevent direct sunlight, and also the rainwater to go inside the building. The second layer of the roof is made of piled oyster shells. Which can let the interior heat go up and emit below the bamboo roof. These butterfly roofs can guide the rainwater to the gutter tower below, acting as water storage. After filtering and purifying, the water can be brought up and reused in the kitchen, bathroom, and workspace as well.
