<p>The construction of hard structures disrupts natural sediment transport, resulting in erosion on the downdrift side. Over the past two decades, this issue has become particularly evident along Puducherry beach following the construction of the Thengaithittu fishing harbour breakwaters. Although efforts were made to counteract erosion and prevent land loss through the construction of seawalls, they did not lead to any significant buildup of the beach. In response, a hybrid approach to beach restoration has been enacted. This combines beach nourishment in eroded sections with the installation of a submerged triangular wedge reef designed to reduce wave energy and create a sheltered zone for sediment deposition. The intricacies of the restoration plan are clarified by considering the seasonal reversal of littoral drift and prevailing wave energy conditions. This understanding helps extend the life of the nourished beach and minimize erosion on the north side. During non-monsoon and southwest monsoon periods, northward sediment transport leads to beach formation to the north, aided by sediment accumulation against the reef. Conversely, during the northeast monsoon, there is a decrease in beach width and volume due to southward sediment transport. During the study period, Puducherry beach experienced a net accretion of 0.51 million m³, indicating a progressive increase from south to north. This sustainable hybrid approach has proven effective in mitigating erosion and stabilizing the Puducherry beach. It also offers a scalable model for future coastal management in similar sediment-starved, erosion-prone environments.</p>
