Special Issue Information

Dear Colleagues,

Prof. Byung Ho Choi, a very active contributor to our coastal engineering community and promoter of our discipline, passed away on 3rd July 2020. During his long career, beginning from the late 1970, he made significant contributions to a diverse range of areas, including theory and modeling of regional and global tides, tropical cyclone induced storm surges and waves, tide–wave–surge-coupled storm surge and storm wave modeling, tsunami modeling and field works, coastal environmental impact assessment due to coastal development, and coastal circulation in East Asian marginal seas. His profound influence spanned from theoretical to numerical and practical coastal engineering and oceanography.

Prof. Byung Ho Choi has spent the 30+ years of his successful career at Department of Civil and Environmental Engineering, Sungkyunkwan University, South Korea, one of the oldest institutes in the world. At the time of his initial recruitment, the department was still in the developing stage, and Prof. Byung Ho Choi had the opportunity to help shape the civil engineering department, spending time and energy to initiate and develop the coastal engineering discipline. He developed a vigorous and productive research group that is truly dedicated to teaching coastal engineering at all levels and educating the next generation of coastal and ocean engineers in South Korea.

Prof. Byung Ho Choi was one of the co-founders of Korean Society of Coastal and Ocean Engineers (KSCOE), renowned for his leadership and initiatives to foster international collaboration on coastal and ocean engineering.

Prof. Byung Ho Choi was a very special person, full of enthusiasm and undeniable energy, complemented by his unique characteristics and sense of humor. He was also a pioneer and never hesitated to try new ideas, often crossing borders of disciplines, which is the legacy he left to his students and colleagues. All of us share the good fortune and privilege to have had him as a dear teacher, friend, and colleague—an extraordinary friend and a terrific professor, from which we all benefited.

We therefore feel obliged and honored to collect a series of papers by his students, friends, and colleagues together in this Special Issue dedicated to Prof. Byung Ho Choi. In this Special Issue, we are interested in articles on coastal processes and coastal dynamics, not only considering tides, waves, storm surges, and tsunamis—which build upon Prof. Choi’s achievements—but also other issues affecting the coastal environment and local and regional circulation in marginal seas, addressing a broad scope and thereby paying tribute to the rich scientific curiosity of Prof. Choi.

To predict extreme weather events, we conducted high-resolution global atmosphere modeling and simulation using high-performance computing. Using a new-generation global weather/climate prediction model called MPAS (Model for Prediction Across Scales) with variable resolution, we tested strong scalability on the KISTI (Korea Institute of Science and Technology Information) supercomputer NURION. In addition to assessing computational performance, we simulated three typhoons that occurred in 2019 to analyze the forecast accuracy of MPAS. MPAS results were also applied to force an ADCIRC (The Advanced CIRCulation) + SWAN (Simulating Waves Nearshore) model to predict coastal flooding over southern Korea. The time-integration of MPAS showed excellent scalability up to 4096 cores of NURION KNL (KNight Landing) nodes, but a serious I/O bottleneck issue was still found after trying two additional I/O strategies (i.e., adjusting the stripe count and using a burst buffer). On the other hand, the forecast accuracy of MPAS showed very encouraging results for wind and pressure during typhoons. ADCIRC+SWAN also generated a good estimate of significant wave height for typhoon Mitag. The proposed variable-resolution MPAS model, under an efficient computational environment, could be utilized to predict and understand the highly nonlinear chaotic atmosphere and coastal flooding in typhoons.
