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.

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.

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.

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.
