Flood Routing in Resevoir using Modified Puls Method

In the design of hydraulic structures it is not practical from economic considerations to provide for the safety of the structure and the system for the maximum-probable flood in the catchments. Small structures such as culverts and storm drainages can be designed for less severe floods because the consequences of a higher than-design flood may not be serious. On the other hand, storage structures such as dams demand greater attention to the magnitude of floods used in design. The failure of these structures causes a huge loss of life and property damage on the downstream of the structure. From this it is apparent that the type, importance of the structure and economic development of the surrounding area dictate the design criteria for choosing the flood magnitude. This project describes the methodology for estimating the design flood and routing the flood for overflow gravity structure for Kol Dam site in Himachal Pradesh and Kakkadavu dam site in Kerala.
