Land Reclamation Impacts on Tidal Landscape Evolution

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract In the past 1000 years, the continuous need for fertile and strategically located land has led to the reclamation of intertidal areas. The direct and short‐term impact of land reclamation is a reduction in intertidal storage space and the loss of ecological value.

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 ...

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.

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 ...

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 ...

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.
