Better Understanding of Coastal Hydrodynamics:
Towards Safer and Sustainable Coasts

Research Interests

Our research interests are basically towards a better understanding of coastal hydrodynamic processes which tend to be highly complex and turbulence-dominant due to a variety of physical factors, for example, irregular geometry, wave breaking, pycnocline, thermocline, flow-structure interactions and natural extreme events in the nearshore area. Therefore, our works easily expand into coastal hazards and environmental impacts associated with coastal hydrodynamics. While the most of our works were done by numerical modelling, some of our researches also cover laboratory experiments and field observations to excel work performances. Engineering-focus projects such as measures for coastal erosions\storm surges\flooding\oil-spills are of particular interests since they require practical insights that Dr. Son had obtained through industrial experiences prior to joining Korea University.

해안유체역학 연구실에서는 해안에서 나타나는 복잡한 흐름기인 현상들에 대해 유체역학적 관점을 토대로 발생 및 변화과정을 이해하고 그러한 현상들이 환경에 미치는 영향을 연구합니다. 최근 지구온난화와 해안지역의 인위적 개발에 따라 해안환경 역시 지속적으로 변화하고 있으며, 이와 맞물려 연안침식, 지진/폭풍해일에 의한 범람, 오염물질 유출 및 확산, 이안류 등 다양한 해안수리학적 현상들도 그 특성을 달리하며 발생하고 있습니다. 따라서 해안유체역학연구실에서는 이론적 해석, 수치모델링 및 수리실험기법을 통해 해역에서 파랑 및 조류 등에 의해 발생하는 다양한 수리현상의 발생기작을 환경의 지속변화에 초점을 맞추어 규명하고, 이를 바탕으로 해안현안들에 대한 효율적 대처방안을 연구합니다. 이를 통해 해안환경의 보전과 재해경감 및 예방을 위한 해법을 강구하고, 방파제 등 구조물 설계의 기준을 제시할 수 있으며, 궁극적으로 해안의 지속가능한 안전환경 구축에 도움을 줄 것으로 기대합니다.

  • 2023 Summer retreat to Jungseon/Samcheok

    CHL headed for Samcheok and Jungseon province to have a 2-day summer break. Our itinerary included exploring the Tsunami Prevention Safety Tower and the beach area in Samcheok. This allowed us to immerse ourselves in both field experiences and relaxation. As the day turned to night, we found comfort in a cozy cabin where we enjoyed a delightful BBQ evening. This excursion provided yet another unforgettable memory, filled with joyful moments and a lot of fun!
