Turbulence, Sediment‐Induced Stratification, and Mixing Under Macrotidal Estuarine Conditions (Qiantang Estuary, China) [PDF]
Journal of Geophysical Research: Oceans, 2019 AbstractTime series of in situ measured velocity and suspended sediment concentration from Qiantang Estuary (China), and estimates of turbulence and sediment stratification parameters are presented. The data span a period of 9 days, and after phase averaged, they are used to explore spring‐neap tidal variations in flow, turbulence, and sediment ...

Numerical simulation of tidal flow field in the Qiantang Estuary bends(钱塘江河口弯道潮流场的数值模拟)
Zhejiang Daxue xuebao. Lixue ban, 2007 钱塘江河口潮流错综复杂，依靠零星的实测潮流资料无法全面描述其流场特征.本文采用Deldt3D模型对钱塘江河口闻家堰至仓前河段的潮流场进行二维数值模拟，着重研究了河口弯道的流场特性.结果表明，河口弯道流场具有跟无潮河流弯道显著不同的特性，如弯道流速向下游递增；涨、落急主流线分歧；涨、落潮流对丁坝工程的响应不同，以及下游弯道水面横比降大于上游弯道.

Salinity prediction in Qiantang Estuary based on Improved LSTM model
Abstract Investigating saltwater intrusion is vital for optimal use of estuarine water resources. Presently, diverse data-driven models, mainly neural network models, have been employed to predict tidal estuarine salinity. However, the high nonlinearity, randomness, and instability of salinity sequences pose challenges for accurate estuarine ...
