High spatial variability in a species‐rich assemblage of diadromous fishes in Hong Kong, southern China

Journal of Fish Biology, Volume 105, Issue 3, Page 663-681, September 2024.
Abstract China has experienced substantial coastal reclamation and damming of rivers. These changes have the potential to impact migrations of diadromous fishes between the sea and fresh waters, but the composition of these fishes and the impacts of barriers to their movement in China have received little attention.

Oscillatory and regularized shock waves for a modified Serre–Green–Naghdi system

Studies in Applied Mathematics, Volume 153, Issue 1, July 2024.
Abstract The Serre–Green–Naghdi equations of water wave theory have been widely employed to study undular bores. In this study, we introduce a modified Serre–Green–Naghdi system incorporating the effect of an artificial term that results in dispersive and dissipative dynamics.

Cetacean stranding records along the Shanghai–Zhejiang coastline in China: implications for distribution and conservation

Frontiers in Marine Science
Cetacean ecology has been poorly studied in the Shanghai-Zhejiang waters of East China Sea, seriously hindering appropriate local conservation practices.

Economic Development Drives Massive Global Estuarine Loss in the Anthropocene

Earth's Future, Volume 12, Issue 4, April 2024.
Abstract Estuaries have great ecological and economic value and sustain both population and economic growth. Global‐scale analyses suggest that human activities drive estuarine area change but these projections neglect direct human‐estuary interactions and socio‐economic feedbacks.

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.

Field testing and numerical modeling of vehicle-induced vibrations on an ancient seawall via an approach slab

Frontiers in Earth Science
The Yanguan Ancient Seawall at the Qiantang River estuary is a nationally protected cultural heritage and an in-service flood defense. Construction activities, such as vehicle crossings, pose risks of vibration-induced damage to this aging structure.

Collision dynamics of dual tidal bores in the Qiantang River Estuary, China

Abstract Dual tidal bores occur in estuaries with specific riverbed morphology, yet the hydrodynamics of their collision remain poorly quantified. In this study, we investigate the collision dynamics of dual tidal bores in the Qiantang River Estuary using field data and a numerical model.
