Spatial and seasonal variations of organic carbon distributions in typical intertidal sediments of China

, 2020
Intertidal zones are the main sites for land-ocean interaction and play an important role in transporting and accumulating organic carbon (OC).

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.

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.

Morphodynamics of Sandbar in a Macro-tidal Estuary: A Model Approach

, 2012
This paper studied the development and the underlying physical mechanisms of the large sandbar in Qiantang estuary, China, using an idealized morphodynamic model. The model coupled shallow water equations, cohesive sediment transport and bed level update

Progress in research of hypoxia in estuaries and coastal areas in China [PDF]

, 2017
对长江、珠江等河口及其近海水域缺氧现象与影响因素进行研究,结果表明,主要分布于长江与珠江河口及其邻近海域的缺氧现象,夏季(6-8月)达到最盛,秋; 冬季消失;长江口的缺氧区域主要位于30.75°N~32°N,122.5°E~123.25°E附近海域,具有南北2个缺氧中心;珠江口缺氧程度相对较; 轻,缺氧区域主要在广州黄埔区河段至虎门水域和伶仃洋;辽河、钱塘江、海河等河口区域也时而出现零星的缺氧现象;水体缺氧受控于多项环境要素,物理层化作; 用是缺氧产生的最初诱因之一,陆源污染物的分解则是重要的耗氧负荷 ...

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.

Environmental, ecological and cultural impacts of tidal bores, burros and bonos [PDF]

, 2009
A tidal bore is a series of waves propagating upstream as the tidal flow turns to rising. It forms during the spring tide conditions when the tidal range exceeds 4 to 6 m and the flood tide is confined to a narrow funnelled estuary with low freshwater ...
