Environmental flow assessment in regulated tropical rivers is often constrained by limited data and strong hydropower alteration. Conventional hydrological approaches based on fixed flow indices rarely account for the ecological complexity required for sustainable management. This study develops an extended species-centred environmental flow assessment framework by integrating hydrological analysis, hydraulic simulations, habitat suitability thresholds, and discharge-water quality analysis. The approach was applied to the downstream of Cirata Dam on the Citarum River, Indonesia. Habitat-based modelling identified an optimal discharge of 93.12 m3/s, maintaining 94% of suitable habitat area, while achieving good water quality conditions would require a discharge exceeding 500 m3/s, which is hydrologically unrealistic. The integrated results demonstrate that determining environmental flows in a regulated river must balance ecological and hydrological feasibility. Flow alone cannot ensure recovery in the context of pollution control, underscoring the importance of combined flow regulation and watershed-scale water management policies.
