Short Summary

This study investigates the hydrological functioning and erosion susceptibility of the Gorgol River tributaries to support sustainable watershed management, finding that southern basin areas with fragile soils are most vulnerable to erosion, primarily driven by rainfall erosivity, and identifying flood-prone zones.

Objective

• To investigate the hydrological functioning and erosion susceptibility of the Gorgol River tributaries to support sustainable watershed management.

Study Configuration

• Spatial Scale: Gorgol River basin (tributaries), Senegal River watershed.
• Temporal Scale: Past 42 years (for temperature increase), July to September (for precipitation patterns).

Methodology and Data

• Models used: Revised Universal Soil Loss Equation (RUSLE).
• Data sources: Satellite-derived climate variables, ground measurements, topographic data, geological data, soil data, land-use data.

Main Results

• A pronounced north–south rainfall gradient exists, with most precipitation occurring between July and September.
• A +1 °C temperature increase was observed over the past 42 years.
• Areas in the southern basin and those with fragile soils are most vulnerable to erosion.
• Rainfall erosivity is the primary driver of soil loss.
• Flood-prone zones were identified, and hydrological regimes characterized.

Contributions

• Provides a scientific basis for targeted interventions in erosion control and flood risk reduction within the Gorgol basin.
• Offers insights into hydrological functioning and erosion susceptibility under climate change and human pressures for sustainable watershed management.
