The subject matter of this chapter revolves around the intersection of hydrodynamics in French lakes with the economic development of their respective territories. The aim is to understand the interactions between the dynamics of these lakes and territorial actors operating within these limnic areas. Each party is subjected to different management approaches, yet none of them take advantage of lake movements. These management strategies are organized based on the specific limnological mechanisms of each lake, including their temporal and spatial characteristics, as well as the risks they pose to human activities integrated into these lake ecosystems. This chapter will specifically focus on unused water and sediment movements as means to interact with local management practices. These phenomena serve as a foundation upon which all actors surrounding these lakes can rely to guide the protective measures implemented for their activities. This chapter aims to provide scientific insights to support decision-making for the actors operating in proximity to these lakes.
