讲座摘要/Abstract:

The water quality of large, deep lakes (such as Lake Geneva, French: le Léman) is strongly influenced by hydrodynamics, particularly in the context of a warming climate. The main hydrodynamical drivers, viz., wind (mechanical), temperature changes (buoyancy) and the Earth’s rotation (Coriolis), give rise to fascinating motions from turbulent mixing to basin-scale seiches. For instance, while basic physical principles predict the stratification of surface waters and their warming-induced buoyancy, complexity arises from the interactions between the warmer surface layers and colder, denser bottom waters. In particular, despite Lake Geneva’s typical state of being stably stratified (i.e., vertical mixing is inhibited), its deepest layers show long periods of gradual warming, signaling the influence of hydrodynamic processes such as mixing, seiches, and vertical exchange. Lake Geneva, as a natural laboratory, offers a rich historical and contemporary case study for understanding these processes. Notably, the pioneering work of François-Alphonse Forel over a century ago laid the foundation for the study of basin-scale motions in lakes, establishing Lake Geneva as an ideal model for exploring how climate change affects both hydrodynamics and water quality. This talk will examine the interactions between hydrodynamic forces and their manifestations at the mesoscale, where appropriate highlighting how these processes are influenced by temperature-driven changes that challenge the resilience of major freshwater lakes.
