Qiantang River tidal bores using kinetic flux vector splitting and Godunov schemes on a triangular grid. Wang et al. (2022) employed a three-dimensional finite volume commu- annual flow of
any rivers. Qiantang River is the largest river in Zhejiang province with a basin area of about 55 000 km2. Except for drinking, it also has functions of power generation, flood control, irrigation,
The Qiantang River, located in eastern coastal China (Fig. 1), is the largest one in Zhejiang Province. It plays a critical role in the sustainable development of Yangtze River Delta, due to
Then, the tidal stream energy resource in the Qiantang River Estuary was assessed. The present work established a 2D numerical model for calculating the power density in the estuary and validated it with in situ water level, tidal current, and suspended sediment concentration measurements.
The Qiantang River has a catchment area of 55,558 km 2 and is 668 km in length. The observed maximum tidal range is 9.15 m, and the maximum flood velocity is more than 10 m/s (Li et al. 2018).
Liu et al. reviewed China's tidal current energy distribution and estimated the theoretical value of tidal current power of about 61.3 TWh/yr. Li et al. addressed China's policies and current status of conversion technologies, as well as opportunities and challenges for tidal current energy development.
When the Qiantang River (QR) tidal bore arrives, the water level suddenly rises by approximately 2 m within seconds; the maximum is more than 3 m. The water flow rapidly changes from ebb tide to flood tide . In the case of a sharp bend in the river or obstruction by buildings, the water column aroused will be more than 10 m.
Since 2016, the tidal current energy demonstration project in Zhoushan has generated more than 1.95 GWh of electricity, with a continuous operation duration of more than 40 months . Great efforts have been made on the design of TCTs and investigation of tidal current resources.
It hosts 91 energy enterprises, which include 63 solar photovoltaic power enterprises and 28 wind power enterprises. "Green energy is the signature industry of Hainan prefecture and our annual output accounts for 54.08 percent of the total energy generated in Qinghai," Qeyang said.
