Revealing Population Connectivity of the Estuarine Tapertail Anchovy Coilia nasus in the Changjiang River Estuary and Its Adjacent Waters Using Otolith Microchemistry

Fishes, 2022
The estuarine tapertail anchovy, Coilia nasus, is a migratory fish with high economic value in China. We collected fish from the Changjiang River (the Yangtze River) estuary, the Qiantang River estuary, and the southern Yellow Sea, and studied their ...

Real-time characteristics of tidal bore propagation in the Qiantang River Estuary, China, recorded by marine radar [PDF]

Continental Shelf Research, 2019
Quantitative real-time observations of a tidal bore in a macro-tidal estuary are difficult and dangerous, particularly in large estuaries. Mathematical and numerical models have been used to predict tidal bore advances; however, to date, there have been no validations of large-scale flow patterns.

Experimental Study on Vertical Bearing and Deformation Characteristics of Qiantang River Ancient Seawall

Buildings, 2023
Situated on the northern bank of the Qiantang River estuary, the ancient seawall serves not only as a national cultural relic but also as an active agent in flood and tide prevention.

Local human activities overwhelm decreased sediment supply from the Changjiang River: Continued rapid accumulation in the Hangzhou Bay-Qiantang Estuary system

Marine Geology, 2017
We investigate the morphological responses of the Hangzhou Bay, China, located immediately south of the Changjiang Estuary, to the drastic reduction of the sediment load from the Changjiang River and the large-scale coastal embankment schemes over past decades.

Characteristics and accumulation model of the late Quaternary shallow biogenic gas in the modern Changjiang delta area, eastern China

Petroleum Science, 2017
The Changjiang (Yangtze) is one of the largest rivers in the world. It formed a huge incised valley at its mouth during the Last Glacial Maximum; the incised-valley fill, approximately 80–110 m thick, supplies an important foundation for the generation ...

The Decadal Changes in Resource and Environmental Carrying Capacity of Estuarine Ecosystem

Haiyang Kaifa yu guanli
From the perspectives of resources, environment, and socio-economic factors, a comprehensive evaluation index system for the resource and environmental carrying capacity of the Qiantang River estuary ecosystem was constructed.

Population Genomics Provides Novel Insights Into Evolutionary Relationships and Local Adaptation of Two Ecotypes <i>Coilia nasus</i>. [PDF]

Ecol Evol
Based on whole‐genome resequencing, we determined that the freshwater‐resident form (C. nasus taihuensis) is an ecotype of anadromous Coilia nasus, not a distinct subspecies. The two ecotypes diverged approximately 4.6 thousand years ago, coinciding with the formation of Tai Lake.

Calculation and study on pollutant degradation coefficients of Qiantang River estuary

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Qiantang River Estuary is a typical macro-tidal estuary in China, with features of strong tidal and high sediment concentration. In order to figure out degradation characterization of the major pollutants of Qiantang River estuary, water samples were taken in Xinsha Island, Changansha Island and Wenyan.

Spatial and temporal distribution of macrobenthos communities and their relationship with secondary front in Hangzhou Bay

Frontiers in Marine Science, 2022
Water quality in Hangzhou Bay is inferior (grade 5) because of discharged from Yangtze River and Qiantang River, and from factories around the bay. This study analyzed relationships between the environment and macrobenthic communities at 44 stations ...

Influence of Tide and Runoff on Saltwater Intrusion in the Qiantang River Estuary, China

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Qiantang River Estuary, as one of main fresh water resources for urban zone, has been threatened by salt water intrusion. Due to the combined influence of tide and runoff, the mechanism of saltwater intrusion is extremely complex.
