Abstract

Aiming at the prevention and control of the water environment of the Puyang River in the upper reaches of the Qiantang River, two-dimensional hydrodynamic model was established to study the influence factors of flushing time of Puyang River in the upper tributary of Qiantang River. The goal is to provide a new way to solve the problem of river water quality. The research results show that under the action of different influencing factors, the flushing time of the Xijiang and Dongjiang has a gradual increase trend from upstream to downstream. However, due to the supporting effect of the Fuchun River flow on the Puyang River outlet, the flushing time of area below Meichi increased first and then decreased from the upstream to the downstream. At the same time, the influence of discharge of Fuchun River on the flushing time roughly extends to the middle and lower reaches of the Xijiang and Dongjiang River. The discharge of Fengqiao River has little effect on the flushing time in the Xijiang River and area below Meichi, and the influence of the discharge of Fengqiao River on the flushing time of the Dongjiang River Basin is roughly 18km~25km away from the entrance of the Dongjiang River. The influence of the discharge of tidal intensity of Qiantang River on the flushing time of the area below Meichi is within 5km of downstream exit. The initial water level and the discharge of the Puyang River are the main factors affecting the flushing time of the river basin, and the discharges of the Fuchun River and the Fengqiao River also have a significant effect on the flushing time.The research results can provide technical support for the prevention and control of the water environment of tidal rivers.
