Flooding poses a substantial risk to infrastructure and communities, especially in at-risk areas such as Sambalpur district in Odisha. This research focuses on reducing flood risk via the structural design of four main interventions: an earthen embankment, a gravity dam, a cantilever retaining wall, and a counterfort retaining wall. From the identified high-risk areas on a flood susceptibility map, every structure was designed taking into account local hydrological factors, geotechnical characteristics, and safety standards. Structural analysis was performed using STAAD.Pro and PLAXIS LE, with designs validated against sliding, overturning, and bearing capacity failures as per applicable IS codes. The results indicate the vital importance of properly designed flood-resistant structures in improving regional resilience and safeguarding crucial infrastructure.
