Poster: PDFAbstractIntroduction
Dam siltation is a critical issue for surface water managers in semiarid climates like Morocco, exacerbated by water scarcity and climate change. Managers face multiple challenges:
- Loss of storage capacity • Risks to dam safety (functioning of outlets and intakes)
- Water quality degradation
- Significant economic losses
Complexity of the Process Siltation is not a single event but a complex chain of processes:
- Water Erosion: Sediment generation in the watershed
- Sediment Transport: Transfer by rivers to the dam
- Reservoir Dynamics: Entry, deposition, and consolidation
Objective
To improve prediction techniques and better understand this phenomenon to implement appropriate control actions for both the design phase and the management/operating phase
