Modeling and simulation of biogeochemical cycles in lakes

  • Category: MIPS Conference #3
  • Dates : March 7, 2025
  • Opening hours: 11:30 a.m. to 1 p.m.
  • Location: Triolet Campus - Building 20 - Physics Amphitheatre - Place E. Bataillon, Montpellier

By Celine Casenave, Research Director at UMR MISTEA in Montpellier since 2011. Trained as an automation engineer and applied mathematician, she conducts research in the modeling, identification and control of deterministic non-linear dynamic systems. Her main fields of application are the control of alcoholic fermentation in wine, the modeling and optimization of agro-ecosystems and the simulation of lake ecosystems.

Summary

Lakes and reservoirs play a crucial role in the water cycle and biodiversity, and provide important ecosystem services (drinking water supply, hydroelectric power, irrigation, flood mitigation, recreational activities). Like many ecosystems, they are heavily impacted by human-induced environmental change. Today, more than half the world's freshwater lakes and rivers are polluted. Lake temperatures are also changing rapidly in response to global warming, making lakes "sentinels" of climate change. The effect on biogeochemical cycles is also significant, as evidenced by the increase in frequency and intensity of cyanobacterial blooms.
In this context, the development of mathematical models to predict changes in the quality of water bodies in response to environmental and anthropogenic forcings is essential to guide managers and decision-makers.
This seminar will present interdisciplinary work on modeling and simulating the dynamics of biogeochemical cycles in lakes, with a particular focus on cyanobacterial blooms.


Modelling and simulation of the biogeochemical cycles in lakes 

Lakes and reservoirs play a crucial role in the water cycle and biodiversity, and provide important ecosystem services (drinking water supply, hydroelectric power, irrigation, flood mitigation, recreational activities). Like many ecosystems, they are heavily impacted by anthropogenic environmental changes. Today, it is estimated that more than half of the world's freshwater lakes and rivers are polluted. Lake temperatures are also changing rapidly in response to global warming, making lakes "sentinels" of climate change. The effect on biogeochemical cycles is also significant, as evidenced by the increased frequency and intensity of cyanobacterial blooms.
In this context, the development of mathematical models that can predict changes in water quality in response to environmental and anthropogenic changes is essential to guide managers and decision-makers.
This seminar will present various interdisciplinary works contributing to the modeling and simulation of biogeochemical cycles in lakes, with a particular focus on cyanobacterial blooms.

Pôle de Research MIPS conferences are designed to raise community awareness of new topics and technological innovations. 

Aimed at a wide audience - students and researchers from all disciplines - they feature the multidisciplinary expertise of the MIPS cluster, its partner clusters and structures, and national and international teams.

They are held on the first Friday of each month at 11:30 a.m., and are followed by a buffet for further discussion.
