Overview

Analysis unveils the water balance dynamics in Lake Fitri, indicating its vulnerability to climatic variability.

Key Points

  • To analyze the hydroclimatic functioning and water balance of the Lake Fitri basin in Chad.
  • Combined rainfall records with in situ hydrological observations.
  • Conducted water balance analysis using spatial remote sensing data.
  • Analyzed seasonal variations in Batha River flows and lake levels.
  • Observed a strong influence of Sahelian climate with a short-wet season.
  • Found that potential evapotranspiration significantly exceeded precipitation.
  • Estimated recharge of about 70-120 mm in 2020, only 14-24% of annual rainfall.
