ASCE has honored Junqiang Xia, Ph.D., M.ASCE, with the 2026 Hans Albert Einstein Award. He was selected for pioneering field-deployed advances in alluvial-river hydraulics by integrating basin-scale water-sediment regulation on the Yellow River with mechanistic bank-erosion forecasting and standards on the Yangtze and delivering agency-endorsed tools that reduce scour risk, enhance flood routing, and boost river-basin resilience.
Xia has made important contributions in sediment transport and river dynamics, successfully employing fundamental principles to solve challenging real-life river engineering problems. For over 30 years he has dedicated himself to the modeling and prevention of water and sediment disasters.
His work includes transformative advances in water-sediment regulation and alluvial river management. He developed a cutting-edge coupled water-sediment regulation model that connects the Middle with the Lower Yellow River reservoirs, for reducing upstream sedimentation while ensuring downstream flood safety.
Xia has also elevated mechanistic insight and operational early warning for erosion control. He proposed new and improved methodologies for diagnosing failure modes at the bank face and toe caused by the combined effects of river flow and drawdown-induced instability and devised novel technologies for early warning systems.
He has quantified flood hazards to people, vehicles, and infrastructure. He simulated flooding phenomena in urban areas and pioneered methods based in alluvial-waterway hydraulic principles for assessing their impact.
To accomplish these objectives, Xia used analytical, field, experimental, numerical, and artificial intelligence tools. It is particularly noteworthy that his work has focused mainly on very large rivers, such as the Middle and Lower Yangtze River and the Lower Yellow River, which typically pose greater difficulties and have received less attention. Furthermore, through his many scholarship contributions, translational work, and service and leadership roles, he has contributed substantially to the profession.
The Hans Albert Einstein Award is given to a member who has made a significant contribution to the engineering profession in the area of erosion control or sedimentation and/or waterway development either in teaching, research, planning, design, or management.
