        Heavy rain causing flooded roadways is a travel headache for residents living in the neighborhood of the Xiao-Dong Underpass in Tainan City. A group of students led by Professor Hsiao-Wen Wang tried to tackle the problem and proposed possible solutions to it.

        The course is named Lowland Flooding and Management which is opened for students taking the International Master Program on Natural Hazards Mitigation and Management at National Cheng Kung University (NCKU), Tainan, Taiwan.

        After months of investigation and experiments, the students shared their research and proposed solutions to the problem at a recent presentation attended by professors, experts and officials from Tainan City government.

        A total of 23 local and international students are divided into five groups to explore the issues behind the flooding.

        One of the five teams proposed short-term solutions include portable pumping system of the onset flooding, safety drill, by passing the traffic and information processing by the media.

        Another team’s short-term plan is to detours while mid-term is to build green infrastructure and long-term is to re-design drainage system.

        “All the proposed ideas are practical and feasible. We will have our proposed solutions come true as part of the policy in the near future,” said Prof. Wang from the Department of Hydraulic and Ocean Engineering.

        Mr. Shao-Bo Peng, Deputy Director of Water Resource Bureau in Tainan City Government said that he is happy to see such a great course at NCKU and appreciate all the efforts made by the students and teachers.

        Mr. Shu-Hsu Wu also from Tainan City Government said, “Prof. Wang’s course is very practical and inspiring. In this course, students deal with real problems. In the past two to three months, students started to figure out the problem and come up with some good solutions today.”

        This course involves the understanding of spatial planning, vulnerability, risk, and resilience to the problem of lowland flooding, according to Prof. Wang.

        It emphasizes more on the systemic understanding that should underlie lowland flooding management and seeks to address issues from a holistic perspective, rather than traditional on-site structure-oriented strategies, she added.






        第5組的彭佩斯、游佳靜、黃孟璇、Lam Nguyen 、Adrienne Dodd等,提出的短期規劃為,於鄰近小東地下道的大馬路口設置LED警示燈,當降雨導致淹水,警示燈即閃爍,提醒用路人車淹水與改道。中程規劃,增加地下道與排水道的通水斷面。長期規劃,設置透水舖面。

        第1組的Jose Elias 、Barahona、Fernando Mixco、Pavel Bratsky、楊琮鈞、蔡維哲等指出,小東地下道淹水原因為,水溝蓋加蓋減少滲流面積、側溝通水斷面不足所致,提出增側溝面積、增加排水溝數量等規劃。

        第2組的陳筱惟、翁傑軒、Ersnt Fiefie、Laxman Maharjan、Ferdian Susanto規劃的長期目標,將小東地下道的積水排入鄰近台南公園的燕潭。短期方案為,媒體傳播警示、洪水警示與抽水系統。
