Analysis of the Hydrological Regime in Small Basins within the Three Gorges Reservoir Area During the Impoundment Period by YIN Siwei, HU Huiling, WANG Yuefeng, LEI Chaogui

“…Hydrological regime is an important problem brought about by the Three Gorges Project and directly influences the development and utilization of water resources and ecological sustainable development in the Three Gorges Reservoir Area.Existing studies mainly focus on the influence of water storage on the main stream of the Yangtze River,with little attention to the runoff variations in small basins of the reservoir area.Based on the daily hydrological data of three typical small basins (Daning River,Pengxi River,and Modaoxi River) in this area from 2003 to 2017,by adopting the methods of trend analysis,runoff concentration degree, and runoff concentration period,the multi-time scale change characteristics of runoff are identified from the aspects of runoff and dispersion degree.Meanwhile,the runoff characteristics before and after 175 m water storage (2003—2008,2009—2017) are revealed,and the influencing factors of runoff variations are discussed.The results are as follows.① The average annual runoff of the Daning River Basin and Pengxi River Basin shows a downward trend,but there are no obvious variations in the Modaoxi River Basin.The monthly average runoff in the three basins varies greatly.The runoff of the Daning River Basin and Pengxi River Basin has a significant decrease in the flood season (July),while that of the Modaoxi River Basin has significant increases in the non-flood season (February),and the extreme value of runoff mainly shows a non-significant downward trend.② The runoff concentration degree and runoff concentration period of each basin show a non-significant decrease or increase respectively.③ After water storage,the runoff concentration period of each basin obviously lags behind the precipitation,the annual runoff distribution tended to be uniform,and the precipitation-runoff correlation decreases.The correlation coefficient of monthly average runoff decreases about 2%~6%,while that of annual extreme value decreases about 3%~12%.The research results can provide a scientific basis for hydrological and water resources management in small basins in the Three Gorges Reservoir Area.…”

Sustainable Development of Water Resources Carrying Capacity Based on System Dynamics: A Case Study of Ganzhou City by WANG Xiaojun, YANG Huan, LI Zhenping, YAN Wenfeng, LAN Sijiao, DU Chao

“…As Ganzhou is the birthplace of Ganjiang River,Dongjiang River,and Beijiang River (“Three Rivers”),the security and sustainable development of its water resources are of great significance to the ecological security and sustainable development of both the Yangtze River Economic Belt downstream and the Guangdong-Hongkong-Macao Greater Bay Area.Thus,seeking the optimal sustainable development mode that Ganzhou's water resources can carry and ensuring the safety and sustainable use of those water resources are currently urgent issues to be solved.In this study,we employ the system dynamics method to build a system dynamics model of Ganzhou's water resources carrying capacity by analyzing its influencing factors and the system feedback loop and dividing the carrying capacity system into three sub-systems of social economy,water resources,and water environment.Moreover,four scenarios of normal development,economic priority,environmental priority,and comprehensive and coordinated development are designed to simulate Ganzhou's water resources carrying capacity during 2020—2035 and dynamically evaluate and simulatively predict its sustainable development capacity under each scenario.The results indicate that among the four scenarios,all the normal development and economic priority scenarios that sorely pursue the continuation of the current development status of social economy and the environmental priority scenario that protects water resources at the expense of social economy development fail to guarantee the sustainable development of water resources and social economy.In contrast,under the comprehensive and coordinated development mode,the chemical oxygen demand (COD) emissions will remain at a low level of 132 900 t by 2035 while economic development rises to a relatively high level,with GDP reaching 1 197.13 billion CNY.It follows that this mode not only ensures economic development but also takes into account the ecological environment.Therefore,the comprehensive and coordinated development scenario that comprehensively considers social economy development,environmental protection,and other factors is the optimal sustainable development mode that can be carried by water resources.…”

Analysis of Ecological Water Replenishment Cycle and Flow Field Distribution Characteristics of Datong Lake by ZHAO Weiming, LIU Qi, SHENG Dong, TAN Jun, HUANG Cao

“…In the post-Three Gorges period,the deep evolution of the relationship between the Yangtze River and Dongting Lake breaks the hydraulic pattern that the water flows into Datong Lake from the northwestern corner and discharges from the southeastern corner of Datong Lake.To study the ecological water replenishment cycle and the characteristics of flow field distribution of Datong Lake under variant environment,we build a two-dimensional hydrodynamic model of water systems based on MIKE 21FM and simulate the hydrodynamic conditions for the project of river-lake connection and ecological water replenishment of Datong Lake.Then,the water replenishment cycle and flow field morphological characteristics of Datong Lake are studied under six scenarios,such as different ecological water replenishment flow and different gate control,and the critical point of ecological water replenishment efficiency is presented.The results reveal that the flow rate distribution of the control scheme of “single in-double out” is more uniform than that of the control scheme of “single in-single out.” …”
