Project Description

Project Context :

The majority of water bodies worldwide are under increasing pressure from climate change, profoundly affecting their physical, chemical, and biological components. These changes pose numerous challenges for water management and quality maintenance, as well as for processes such as storage and greenhouse gas emissions. Monitoring, combined with modeling of thermal trajectories and biological activity, is essential to anticipate these impacts and guide management and adaptation measures.

Project Objectives :

The PREDILAC project combines monitoring and research approaches to characterize the responses of water bodies to climate change. The monitoring component focuses on the coordination of the "RNT water bodies" network. The research component includes four sub-objectives: modeling future thermal trajectories, modeling past thermal trajectories accounting for water level fluctuations, quantifying greenhouse gas fluxes, and studying the spatial dynamics of phytoplankton at a pilot site.

Project Results

The project aims to refine the thermal characterization of the region’s water bodies by providing, in addition to mean epilimnion and hypolimnion temperatures, indicators such as thermocline depth and daily temperature extremes. This level of detail will better assess community exposure to climate warming. The impact of water level fluctuations on thermal structures will be analyzed. The GLM database will also link existing or developing AED modules and produce indicators on blooms and GHG fluxes.
