Factors such as climate change, urbanization, poor infrastructure, and extreme weather events collectively increase the risk severity of flooding. Efficient flood management is essential for mitigating risks caused by incidents, especially in areas Idukki, Kerala, which has substantial monsoonal rainfall. The floods 2018 2019 exposed flaws Idukki multi-reservoir system, emphasizing necessity enhanced operational strategies. This study develops a comprehensive hydraulic model utilizing MIKE 11 system to simulate multi-reservoir's response scenarios, necessitating optimization water flow strategies improve management. modeling framework incorporates one-dimensional hydrodynamic model, calibrated validated using historical data from 2013, applying conservation mass principles compute inflows outflows within reservoir system. findings demonstrate robust correlation between simulated actual levels, indicated calibration metrics coefficients, ranging 0.90 0.96, Nash-Sutcliffe 0.95 0.98. In floods, operations were strategically controlled, leading effective pre-discharge procedures optimized keep levels safe limits. exhibited its predictive abilities during peak inflow situations, validating that control measures can substantially reduce downstream flooding risks. results underscore significance adaptive operations, demonstrating model's effectiveness real-time decision-making enhancing adaptability systems susceptible like Idukki.
