Large‐Scale Evaluation of Beach Morphodynamic Evolution and Environmental Drivers Along China's Eastern Coast Through Long‐Term Landsat Analysis

Earth's Future, Volume 13, Issue 9, September 2025.
Abstract Beach evolution severely impacts the economy and social well‐being of coastal communities, posing a threat to the safety of coastal infrastructure. Under the influence of rising sea levels and other various environmental variables, the coastal morphology of Eastern China has undergone significant changes, particularly in the low‐lying beach ...

Four‐Dimensional Mapping of Sea Temperature and Salinity in the Coastal Waters Based on Generalized Spatio‐Temporal Autoregressive Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract The lack of sufficient in‐situ ocean observations significantly limits progress in studying the underwater marine environment. Fully analyzing the 4‐dimensional distribution of observation data, especially the changes over time and depth, allows for a broader and deeper application of marine data mining.

Source and Ecological Risk Characteristics of PAHs in Sediments from Qinhuai River and Xuanwu Lake, Nanjing, China

Journal of Chemistry, Volume 2017, Issue 1, 2017., 2017
In order to investigate the residual characteristics, sources, and ecological risk of PAHs in sediment from urban rivers, the sediments of 15 typical sites from Qinhuai River and Xuanwu Lake, which are typical urban rivers and lake, were collected from October 2015 to July 2016; the sources of PAHs in sediment were also identified by several methods ...

Effect of contracted river on tidal bore in Qiantang Estuary

Shui kexue jinzhan
Since the late 1960s, the Qiantang Estuary has been narrowed on a large scale, significantly changing the water-sediment dynamics, riverbed evolution and their interaction processes.

Monitoring Discharge and Suspended Sediments in the Yangtze River Tidal Reach Using Coastal Acoustic Tomography

Water Resources Research, Volume 61, Issue 3, March 2025.
Abstract Conventional methods of measuring water discharge and suspended sediment concentration (e.g., water sampling and moving acoustic Doppler current profiler [ADCP]) present challenges in large tidal rivers due to temporal and spatial constraints.

Comparative Experimental Study of Geotube Groins and Mixed Clay–Geotube Groins under Various Flow Conditions [PDF]

, 2023
During the cofferdam construction of the toe reinforcement project at the Qiantang River Estuary, the scouring of the riverbed at the groin head often led to the collapse of geotube groins due to strong tidal currents.

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.
