Sea‐Level Change in Hong Kong From Tide Gauges, GNSS, and Satellite Altimetry

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract As a densely populated, highly urbanized coastal city, Hong Kong is particularly vulnerable to sea‐level rise, which amplifies flood risk and threatens coastal infrastructure, economies, and ecosystems. We combine observations from tide gauges, conventional gridded satellite altimetry, coastal‐retracked altimetry, and Global Navigation ...

Estimation of Sugarcane Yield Using a Machine Learning Approach Based on UAV-LiDAR Data

Remote Sensing, 2020
Sugarcane is a multifunctional crop mainly used for sugar and renewable bioenergy production. Accurate and timely estimation of the sugarcane yield before harvest plays a particularly important role in the management of agroecosystems.

A cascading reaction by hydrological spatial dynamics alternation may be neglected

Environmental Research Letters, 2022
Water regime changes play a critical role in the structure and function of watershed ecosystems. However, most previous studies focused only on static fixed-point quantitative change at a given time, ignoring the hydrological spatial distribution states ...

Experimental study on the thixotropic strength of the marine soft clay from the Yangtze River estuary

Frontiers in Marine Science
Soft clay in the offshore area of the Yangtze River estuary has been investigated considering its basic physical properties. Forty-five unconfined compressive strength tests were conducted on the remolded marine soft clay to investigate the impacts of ...

Low Denitrification, Anammox, and Dissimilatory Nitrate Reduction to Ammonium Rates in a Low Disturbance Mangrove‐Saltmarsh System Using an in Situ Intact Chamber Method

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Mangroves and saltmarshes can remove anthropogenic nitrogen (N) moving from the land to the ocean, but many previous N cycling measurements used destructive sampling procedures that excluded important habitats such as crab burrows, pneumatophores, and saltmarsh vegetation.

Impact of reintroduced elaphure on soil carbon storage in eastern Jiangsu Province, China

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction The reintroduction in the wild of elaphure or Père David's deer (Elaphurus davidianus) in a coastal wetland in Dafeng, Jiangsu Province, in the absence of an apex predator has been shown to negatively impact the ecosystem through overgrazing, which, over time, can also degrade the soil's ability to sequester atmospheric carbon ...

Dissolved organic nitrogen in the river test and estuary

, 2005
Studies of nutrients in rivers and estuaries have generally focused on dissolved inorganic nitrogen (DIN), although this accounts for only a part of the total nitrogen (TN) in these systems.

Numerical simulation of sediment transport characteristics under tidal action in the Qiantang estuary

Frontiers in Marine Science
The Qiantang River Estuary (QRE) is a typical alluvial estuary featured by intense tidal bores, high suspended sediment concentration, and drastic bed erosion-deposition processes.

Differential growth dynamics of common salt marsh species Spartina alterniflora and Juncus roemerianus under varied sediment amendments

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Many coastal wetlands are at high risk of degradation or loss due to sea‐level rise. Restoration techniques for maintaining coastal marshes are paramount, with thin‐layer placement (TLP) emerging as one feasible solution. Despite TLP's utilization, additional research is needed on species‐ and sediment‐specific responses ...

Critical discharge at Datong for controlling operation of South-to-North Water Transfer Project in dry seasons

Water Science and Engineering, 2008
Previous research shows that there is a strong correlation between saltwater intrusion in the Yangtze Estuary and discharge at Datong. In the near future, the discharge of the Yangtze River during dry seasons will decrease due to the construction and ...
