Numerical Simulation of the Tidal Flow and Suspended Sediment Transport in the Qiantang Estuary

Journal of Waterway, Port, Coastal and Ocean Engineering, 2012
AbstractResults from a numerical modeling study are presented to investigate the tidal elevations, tidal current velocity, bed deformation, and suspended sediment concentration in the Qiantang Estuary, China. The Qiantang Estuary is well-known for its macrotide, which generates a hydrodynamically complex environment.

Effect of dike line adjustment on the tidal bore in the Qiantang Estuary, China

Journal of Hydrodynamics, 2017
In this paper, the effect of the dike line adjustment on the Qiantang Tidal Bore (QTB) is studied by physcial experiments. A lab-scale physical model of the Qiantang Estuary is built and the tidal bore is generated. With this model, the formation and pro-pagation processes of the tidal bore are simulated with or without the dike line adjustment.

The Seawall in Qiantang Estuary

, 2002
The seawall (sea dike) situated in the estuarine reach of the Qiantang Estuary is subjected to the strong, destructive action of the world-renowned Qiantang bore; in Hangzhou Bay, on the other hand, the dike is subjected to strong wave action. The seawall protects the vast lowlands of the Taihu Lake plain on the north bank and the Xiaoshan-Shaoxing ...

Tributary inflows enhance the microplastic load in the estuary: A case from the Qiantang River

Marine Pollution Bulletin, 2020
Microplastics (MPs) in the surface water of the Qiantang River and its tributaries were investigated in this study, to evaluate the contribution of riverine discharge on emerging pollution load in the Hangzhou Bay. The abundance of MPs (mean 1183 ± 269 particles/m3) showed spatially and temporally heterogeneous in the surface water.

Reclamation and River Training in the Qiantang Estuary

, 2002
The Qiantang Estuary, with an upstream boundary at the tidal limit near the Fuchunjiang hydro-power station and a downstream boundary at the mouth of Hangzhou Bay, is a macro-tidal estuary that is world-renowned for the magnificent tidal bore in the estuarine stretch between Wenyan and Ganpu.

Characteristics of tidal-bore deposits and facies associations in the Qiantang Estuary, China

Marine Geology, 2014
Abstract The characteristics of tidal-bore deposition in the Qiantang Estuary are studied on the basis of core strata and grain-size data, and lateral and longitudinal associations with other sedimentary facies are synthesized. A typical depositional package by tidal bores and associated flows is generally initiated with (1) an undular/planar erosion

Law of Salt Tide Intrusion of the Qiantang Estuary and Its Numerical Simulation

, 2020
The Qiantang Estuary is characterized by strong tidal bore, high sediment concentration, severe erosion/deposition and frequent human activities. The law of saltwater intrusion is different from other general tidal estuary. This chapter reveals the law of interaction among runoff, channel volume and salinity by means of the analysis of the long-term ...

Provenance of Holocene sediments in the outer part of the Paleo-Qiantang River estuary, China

Marine Geology, 2015
Abstract Core SE2 from the landward part of the modern Qiantang River (QR) estuary contains a 50 + m-thick succession of late Pleistocene to Holocene deposits that records the transgressive–regressive environmental transition from fluvial sedimentation, through a paleo-estuary phase and shallow-marine deposition, to the modern estuarine setting.

Salinity Time Series Prediction and Forecasting Using Dynamic Neural Networks in the Qiantang River Estuary

Advanced Science Letters, 2012
The early warning of saltwater intrusion is an important work for ensuring the drinking water supplies. To forecast and predict the daily maximum salinity for the water withdrawn for the waterworks located along the Qiantang River, the nonlinear autoregressive networks with exogenous inputs (NARX) model was applied.
