Better Understanding of Coastal Hydrodynamics: Towards Safer and Sustainable Coasts
The Coastal Hydrodynamics Lab investigates the physics of complex flows driven by waves and currents along the coast, and develops technologies for predicting and preparing for coastal hazards. We build high-fidelity computer simulations that reproduce how tsunamis and storm surges originate and reach the shoreline, and integrate artificial intelligence to rapidly analyze large numbers of scenarios and enable near-real-time forecasting. Developing faster and more accurate simulation tools is at the core of what we do. Building on this foundation, we study a wide range of coastal phenomena — typhoon forecasting, shoreline and seabed morphological change, oil spill transport, and rip currents — while also assessing how climate change may reshape future coastal hazard risks. Our ultimate goal is to reduce disaster impacts, improve the design of coastal structures such as breakwaters, and contribute to a coastal environment where people and the ocean can coexist safely.
해안유체역학 연구실은 파도와 해류가 해안에서 만들어내는 복잡한 흐름의 원리를 밝히고, 이를 바탕으로 해안재해를 예측하고 대비하는 기술을 개발하는 곳입니다. 지진해일과 폭풍해일이 어떻게 발생하고 해안에 도달하는지를 컴퓨터 시뮬레이션으로 정밀하게 재현하며, 여기에 인공지능 기술을 결합해 수많은 시나리오를 빠르게 분석하고 실시간에 가까운 예측이 가능하도록 연구하고 있습니다. 더 빠르고 더 정확한 시뮬레이션 기술을 만드는 것이 연구실의 핵심 역량입니다. 이를 토대로 태풍 예측, 해안 지형 변화, 기름 유출 확산, 이안류 등 연안의 다양한 현상을 연구하고, 기후변화가 가져올 미래 해안재해의 위험도 평가하고 있습니다. 저희 연구는 재해를 줄이고, 방파제 같은 해안 구조물의 설계를 더 합리적으로 만들며, 궁극적으로 사람과 바다가 안전하게 공존하는 해안환경을 만드는 데 기여하고자 합니다.

provided deep insights into the evolving field of fluid dynamics and oceanography.
2024 Summer Research Trip to Jungseon
We departed to Jungseon province for a two-day summer research trip. Especially, Prof. Na from the Kumho Institute of Technology,
a former CHL post-doc, joined our trip with his undergraduate interns. This trip offered a perfect blend of field experiences and relaxation,
creating an enriching and enjoyable atmosphere. A delightful BBQ, sharing laughter and stories late into the night, added another chapter of our joyful memories.
CHL Participates in ICCE 2024 in Rome, Italy
The CHL team, including Prof. Son, Junsu, and Jihyun, attended the ICCE 2024 conference held in Rome, Italy. Each of us delivered engaging talks on the topic of coastal disasters, sharing insights and discussing innovative approaches with the global research community.
Beyond the academic exchange, we were captivated by the timeless charm and romantic beauty of Rome, making this conference experience truly unforgettable.
Prof. Son visited UTM in Malaysia
Prof. Son and other three Korean experts in climate change and hydraulic engineering visited
Universiti Teknologi Malaysia(UTM) for attending International Symposium on Hydro-Climate ,
co-organized by BK21 FOUR of Korea University and Centre for River and Coastal Engineering in UTM.
