Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming. [PDF]

open access: yesAdv Sci (Weinh)
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Laboratory simulation of soil respiration response to environmental conditions in intertidal zones of Jiangsu Province, China

open access: yesWater Science and Engineering, 2022
As major contributor to the blue carbon sink, intertidal zones play a crucial role in the global carbon cycle. In recent years, more attention has been given to the carbon cycle in intertidal wetlands.

Harnessing the potential of the multi-indicator palaeoecological approach: an assessment of the nature and causes of ecological change in a eutrophic shallow lake [PDF]

open access: yes, 2015
SUMMARY 1. Multi-indicator palaeoecological studies have become increasingly popular over the last decade as the need for a more complete understanding of lake ecological histories has increased.

Alternative Attractors of Shallow Lakes [PDF]

open access: yesThe Scientific World JOURNAL, 2001
Ponds and shallow lakes can be very clear with abundant submerged plants, or very turbid due to a high concentration of phytoplankton and suspended sediment particles. These strongly contrasting ecosystem states have been found to represent alternative attractors with distinct stabilizing feedback mechanisms.

On the optimally controlled stochastic shallow lake

open access: yesInternational Journal of Control, 2023
We consider the stochastic control problem of the shallow lake and continue the work of G. T. Kossioris, Loulakis, and Souganidis (2019) in three directions. First, we generalise the characterisation of the value function as the viscosity solution of a well-posed problem to include more general recycling rates.

Evaluating the influence of lake morphology, trophic status and diagenesis on geochemical profiles in lake sediments [PDF]

open access: yes, 2010
Recent geochemical studies provide evidence that changes in vertical distributions of nutrients in lake sediments are driven by anthropogenic activities, based primarily on trends of increasing concentrations in upper sediment layers.

Experimental Study on the Curing Effect of Dredged Sediments with Three Types of Curing Agents

open access: yesMATEC Web of Conferences, 2016
Sediment solidification technology is widely used to dispose dredged sediment, three types of curing agents were used in this study to solidified the dredged sediment from shallows in Nantong with three types of curing agents: JY, ZL and FJ.

Increasingly frequent extreme weather events urge the development of point-of-use water treatment systems

open access: yesnpj Clean Water, 2022
The frequency of extreme weather events, including floods, storms, droughts, extreme temperatures, and wildfires, has intensified globally over recent decades due to climate change, affecting human society profoundly.

Wind control on the accumulation of heavy metals in sediment of Lake Ulubat, Anatolia, Turkey [PDF]

open access: yes, 2009
Freshwater Lake Ulubat (zmean = 1.5-2.0 m and Area = ~138 km2), NW Anatolia, Turkey was filled in by fine-to-medium-grain silts during the late Holocene.

Temporal and spatial variations in phytoplankton productivity in surface waters of a warm-temperate, monomictic lake in New Zealand [PDF]

open access: yes, 2010
Surface phytoplankton productivity measurements were carried out in morphologically complex Lake Rotoiti with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations.
