Morphodynamics of the Qiantang Estuary, China: Controls of river flood events and tidal bores

Marine Geology, 2018
Abstract The importance of seasonal variations in river discharge on the morphological development of estuaries has been recognized in recent years, yet in situ observations about such variations are rare. Here we report a long-term dataset of bathymetry in the middle reach of the Qiantang Estuary, China, characterized by the presence of a large ...

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.

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.

Contaminant occurrence, water quality criteria and tiered ecological risk assessment in water: A case study of antifouling biocides in the Qiantang River and its estuary, Eastern China

Marine Pollution Bulletin, 2023
Antifouling biocides may cause adverse effects on non-target species. This study aims to determine the distribution, sources, and ecological risks of antifouling biocides in the surface waters of the Qiantang River and its estuary in eastern China. The concentrations of total antifouling biocides were ranged from 12.9 to 215 ng/L for all water samples.

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.

Physical Drivers of Monthly Variation in Phytoplankton Community in the Tidal Freshwater Zone of the Macrotidal Qiantang River Estuary, Eastern China: Implications for Reducing the Risk of Harmful Cyanobacterial Blooms

Journal of Geophysical Research: Oceans, 2023
AbstractThe Qiantang river estuary flows into Hangzhou Bay, on the East China Sea, and has one of the largest tidal bores worldwide. The tidal freshwater zone (TFZ) in this shallow macrotidal estuary is subjected to strong riverine and marine forcings.

Source‐to‐sink analysis for the mud and sand in the late‐Quaternary Qiantang River incised‐valley fill and its implications for delta‐shelf–estuary dispersal systems globally

Sedimentology, 2021
AbstractThe Changjiang (i.e. the Yangtze River) debouches a huge amount of sediment to the East China Sea and exerts a significant effect on the evolution of the down‐drift Qiantang River system. This study quantitatively documents the temporal change in the import of Changjiang sand and mud to the late Quaternary Qiantang River incised valley by ...

Salinity and Turbidity Gradients Driven Spatial Heterogeneity of Phytoplankton Community in the Eutrophic Macrotidal Qiantang River‐Estuary‐Coastal Sea Continuum

Journal of Geophysical Research G: Biogeosciences
Abstract The river‐estuary‐coastal sea continuum is usually characterized by drastic tidal fluctuations and significant spatial gradients in salinity, turbidity, and nutrients. However, the response of the phytoplankton community in the continuum to such physicochemical variations remains poorly understood. Here, three cruises in dry,
