Stimulating effects of whooper swans’ behaviors on nutrient releasing from the sediments caused by different human feeding intensities in the swan Lake, China

open access: yesEcological Indicators, 2023
In many shallow water lakes of China, as the numbers of tourists observing waterflow increases, the amount of supplemental food provided to waterflow also increases. However, little attention has been paid to the role of waterfowl’s behavior perturbation

Regime Shifts in Shallow Lakes [PDF]

open access: yesEcosystems, 2007
Every now and then the usual scenario of fluctuations around trends in ecosystems is interrupted by sharp shifts to a different regime (Scheffer and others 2001; Carpenter 2003). Similarly, reconstructions of past climatic dynamics reveal various spectacularly rapid changes punctuating episodes of relative stability (Rial and others 2004), and also ...

Internal phosphorus loading in a small shallow Lake: Response after sediment removal.

open access: yesScience of the Total Environment, 2020
Mankind is taking advantage of numerous services by small shallow lakes such as drinking water supply, irrigation, and recreational function; however, many of these lakes suffer from eutrophication.

Invasive Aquatic Plants as Ecosystem Engineers in an Oligo-Mesotrophic Shallow Lake. [PDF]

open access: yesFront Plant Sci, 2018
Exotic hydrophytes are often considered as aquatic weeds, especially when forming dense mats on an originally poorly colonized environment. While management efforts and research are focused on the control and on the impacts of aquatic weeds on ...

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.

Reconsideration of wind stress, wind waves, and turbulence in simulating wind-driven currents of shallow lakes in the Wave and Current Coupled Model (WCCM) version 1.0 [PDF]

open access: yesGeoscientific Model Development, 2022
Wind stress, wind waves, and turbulence are essential variables and play a critical role in regulating a series of physical and biogeochemical processes in large shallow lakes.

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.

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.

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.

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.
