Short Summary

This study quantifies rainfall deficits and monitors spatio-temporal precipitation trends (1991-2024) in the Bouregreg and Chaouia watersheds to assess their impact on surface water resources, revealing a significant water shortage driven by climatic and anthropogenic factors.

Objective

• To quantify the rainfall deficit in the Bouregreg and Chaouia watersheds.
• To statistically monitor spatio-temporal trends in precipitation in the Bouregreg and Chaouia watersheds.
• To detect the impact of precipitation trends on the evolution of surface water resources (1991-2024).
• To highlight the strategy adopted to face water scarcity in the basin's large cities.

Study Configuration

• Spatial Scale: Bouregreg and Chaouia river basin/watersheds, including the Sidi Mohamed Ben Abdellah (SMBA) dam and coastal cities from Kenitra to Casablanca.
• Temporal Scale: 1991-2024 (34 years).

Methodology and Data

• Models used: Descriptive statistics, spatial remote sensing.
• Data sources: Rainfall indices (implying observational data), spatial remote sensing data (for mapping water surface area), data on surface water resources (e.g., dam reservoir levels/areas).

Main Results

• A remarkably visible water shortage was identified throughout the Bouregreg and Chaouia basin.
• This water shortage is attributed to multiple climatic and anthropogenic factors.
• Main drought sequences were determined, and spatio-temporal trends in rainfall indices were monitored.
• The surface area occupied by water at the Sidi Mohamed Ben Abdellah dam was mapped, showing a downward trend.

Contributions

• Provides a quantitative assessment of rainfall deficit and spatio-temporal precipitation trends over a 34-year period (1991-2024) in a critical Moroccan basin.
• Integrates climatic and anthropogenic factors to explain the observed water scarcity.
• Highlights the strategic responses to water scarcity in the region's major urban centers.
