科技日报：新时期淤地坝系平衡理论与优化布局关键技术研究项目启动

Core Insights - The project "Research on the Balance Theory and Key Technology of Silt Dams in the New Era" has been officially launched in Zhengzhou, Henan, focusing on creating a new model for dam construction and operation that emphasizes systematic construction, collaborative governance, intelligent management, and sustainable benefits [1] - The project aims to address the urgent need for balanced, safe, and high-quality silt dam systems in response to the increasing challenges posed by extreme rainfall in the Loess Plateau region, which threatens the safety of dam engineering [1] Group 1 - The project is led by the Yellow River Water Resources Scientific Research Institute in collaboration with several organizations, including the Yellow River Survey and Planning Design Research Institute, Xi'an University of Technology, and Xi'an Yellow River Planning and Design Co., Ltd [1] - The research focuses on four key areas: the impact mechanism and simulation of silt dam systems on small watershed sediment transport, the collaborative balance mechanism of water-sand-agriculture-stability, spatial optimization technology based on balance theory, and the development of an intelligent service and risk management platform for silt dam systems in the Loess Plateau [1] - The project is expected to significantly enhance flood safety, food security, and ecological safety in the river basin, while also advancing the foundational theory and key technology research related to silt dams in China [1] Group 2 - The balance theory of silt dam systems, which began in the 1950s, involves the scientific planning and arrangement of interconnected silt dams that are of varying sizes and complementary functions, aiming for efficient control and utilization of water and sediment resources [2] - The project leader, Dr. Zhang Pan, describes the research as enabling a group of silt dams to function like a well-coordinated team, effectively managing the water and sediment in the watershed for long-term harmonious operation [2]
