Overview

Observational study reveals extreme rainfall drives water balance in Lake Fitri, highlighting the importance of sustainable management.

Key Points

  • The lake's water balance is significantly affected by short and intense rainfall events during the wet season.
  • Recharge of Lake Fitri is episodic, accounting for only 14–24% of total annual rainfall, based on data from 2020.
  • Hydrological modelling captures seasonal dynamics, but underestimates peak floods due to transmission losses.
  • The findings emphasize the vulnerability of the lake's hydrosystem, suggesting a need for improved monitoring.
