The condition of water courses changes with floods, vegetal growth and human activity. A continuous maintenance of water courses is thus necessary to preserve its various functions, as safety, natural habitat and recreation space.
« A lack of care is worse than a lack of science. »
Benjamin Franklin, American scientist and politician
The challenge of a maintenance plan can be described as follows:
- Flood mitigation: prevent risks due to sedimentation, erosion and damages on mitigation structures or the reduction of the flow section.
- Preserve the ecological functions by maintaining the ecosystem, control of eutrophication and invasive plants or trimming of woody banks.
- Regulation of leisure activities (public paths, aquatic sports ...)
Based on hazard assessment, ecological issues and social and economic interests, we define the priorities and the interventions necessary to maintain a water course in a good condition.
