Water erosion in the Gourou watershed (Côte d'Ivoire) - Rainfall variability and water erosion in the Gourou watershed: Factors, mechanisms and modelling

A study of the dynamics of interannual rainfall in Abidjan over the period 1985-2017 revealed an increase in rainfall. The amount of rainfall increased by 4.9%, with an average height of 79.6 mm. The Abidjan airport station shows a break in the time series. Daily rainfall is also high, with 125 days of rainfall >20mm.As for soil loss dynamics, the Gourou basin records a soil loss of 1,429,685.13 tonnes per year. It is more concentrated in the north and centre of the basin. This soil loss essentially contributes to the dynamics of sediment flow in the basin's talweg, particularly in the south. Soil loss has considerable health, environmental and socio-economic consequences.
