Tetsuya Sumi  is a professor at the Water Resources Research Center, Disaster Prevention Research Institute, Kyoto University, Japan. He has a degree in civil engineering from Kyoto University. Subsequently, he worked for the Japanese Ministry of Construction. His specialties are hydraulics and dam engineering, with particular emphasis on integrated sediment management for reservoir sustainability and river basin environment improvement. He has contributed to several international associations and conferences, such as IAHR, ISRS, and ISE. He organized the 2nd International Workshop on Sediment Bypass Tunnels in 2017 in collaboration with ETH-Swiss and NTU-Taiwan. He recently conducted a general report of Q100 'RESERVOIR SEDIMENTATION AND SUSTAINABLE DEVELOPMENT' at the 26th ICOLD Congress, Vienna, Austria, in July 2018.

Sameh A. Kantoush  is currently an associate professor at Disaster Prevention Research Institute (DPRI), Kyoto University. He received his master's and doctorate degrees in civil and environmental engineering from Saga University in Japan and the Swiss Federal Institute of Technology Lausanne (EPFL) in Switzerland, respectively. Prior to joining Kyoto, he served at the German University in Cairo (GUC) as an associate professor in the Civil Engineering Program. He is a member of the Japan Society of Civil Engineers (JSCE) and Syndicate of Engineers in Egypt. The industrial expertise of Dr. Kantoush is predominantly in infrastructure projects at multinational consulting firms in many countries. His research interests span the fundamentals of shallow flow and sediment transport, wadi flash floods, reservoir sustainability, ecohydraulics, dam impacts, and sediment management techniques.

Mohamed Saber  is currently working as a specially appointed associate professor of the Water Resources Research Center, the Disaster Prevention Research Institute (DPRI), Kyoto University. He has a Ph.D. in Hydrology from Kyoto University, Japan, and has worked as an assistant professor at the Geology Department, Faculty of Science, Assiut University, Egypt. Saber has experience working and holding different positions, such as a senior researcher, Water Resources Research Center Disaster Prevention Research Institute, Kyoto University, Japan; a visiting professor, Geological Eng., Middle East Technical Univ., Turkey; a postdoctoral researcher, the University of Louisiana at Lafayette, LA, USA; a postdoctoral researcher, Kyoto University; and a research assistant, GCOE_ARS Project, Kyoto University, DPRI, Japan. Mohamed participated in more than 50 different publications and supervised more than 20 undergraduate, professional diploma, master's and doctorate students. His research interests are mainly focused on flood forecasting and risk management, hydrometeorological analysis and climate change, water resources management, reservoir sedimentation management, and remote sensing and GIS applications, as well as machine learning techniques in flash flood risk assessment.
