Concrete gravity dams are critical components of water resource infrastructure, necessitating a deep understanding of their dynamic behaviour for ensuring safety and reliability. This study investigates the dynamic response of concrete gravity dams, focusing on the spillway structure, essential for water flow management and flood risk mitigation. Utilizing advanced finite element method (FEM) analysis and computational modelling techniques, the study simulates various loading conditions, including hydrostatic pressure, hydrodynamic pressure, uplift pressure, seismic forces, and sediment pressure. Adhering to Indian Standard guidelines, stability analysis is conducted to assess structural responses comprehensively. Results reveal significant stress variations under diverse loading scenarios, highlighting the necessity for thorough structural analysis to ensure dam resilience. While offering actionable insights for engineering practice and risk management, the study acknowledges limitations and suggests avenues for future research to enhance analysis comprehensiveness and applicability.
