Abstract
The paper initially describes about the details of the Ajwa Dam and further about the scenario of breaking of Ajwa Dam. The Ajwa Reservoir is located 20 km north-east of Vadodara city with waste weir and outlet works. The major reason of Vadodara being flooded in heavy rains is due to the release of water from Ajwa Reservoir. The attempt is made to study the disaster effect in the event of breaking of Ajwa Dam. Software ArcGIS, HEC-GeoRAS and HEC-RAS are used for the dam break analysis. Prediction of outflow hydrograph at various river station is generated with the help of USACE Hydrologic Engineering Center’s River Analysis System software i.e. HEC-RAS. Maximum water surface elevation, velocity in the channel and discharge for a particular station of river in the downstream is described as a result of dam break. Floodplain inundation map is generated for the downstream tail reach.
