Influence of the Shihutang Navigation-Power Junction Project Operation on Hydrodynamic Characteristics of the Ganjiang River
The construction of a reservoir on the river can meet the social requirements for irrigation, navigation, water supply, and power generation in the area. However, reservoir development also disrupts the natural flow continuity of the river, leading to fundamental changes in important water environmental factors such as water temperature, water quality, morphology, and water level. In this study, the Shihutang navigation-power junction project mainly affects the middle reaches of the Ganjiang River, the Wan’an to Xiajiang section is taken as the study area, and a one-dimensional hydrodynamic mathematical model of the middle reach of the Ganjiang River is established. The model is calibrated and validated based on measured water level and discharge data in order to study the influence of the Shihutang navigation-power junction project operation on the hydrodynamic characteristics of the middle reach of the Ganjiang River. The results show that the changes in water level, discharge, and velocity in the upstream and downstream areas are generally consistent before and after the operation of the Shihutang navigation-power junction project. The operation of the Shihutang navigation-power junction project has a significant influence on the hydrodynamic characteristics at the dam site, with the influence decreasing as the distance from the dam site increases.
