In the Atlas Mountains, snow acts as a natural water reservoir. Climate warming threatens this regulation function. Snowmelt sustains streamflow during the dry season.
• Quantify future changes in snowpack dynamics.
• Assess impacts on hydrological regimes.
• Identify implications for water-resource management.
Water Resources Management
•Reduced summer flows → need for adapted reservoir operation.
• Increased pressure on drinking water supply and irrigation.
Climate Adaptation Planning
Prioritize demand management and efficiency (agriculture, urban).
Integrate snow loss into long-term water strategies.
Hydropower and Energy
Decreasing and more variable inflows → reduced generation reliability.
Monitoring and Early Warning
Strengthen snow and climate monitoring networks.
Improve seasonal forecasting for drought preparedness.
