英文摘要: In this study, a two-dimensional hydraulic routing model was applied to a sudden failure scenario for the Atasu Dam in Trabzon, Turkey. The goal was to simulate spreading and propagation of a dam break flood wave along a narrow valley into a downstream city center with many buildings. Flow properties along the downstream were routed according to diffusive and dynamic wave models represented by Saint–Venant equations. Maximum flow depth, maximum flow velocity, and time moment of the maximum flow depth maps are shown in a Geographic Information System environment. The results predict that flow depths could reach approximately 8 m in the residential area, and this would be achieved approximately 32 min after the dam-break event. Houses in a large section of the city center would be under the maximum flow depths. The results of this study demonstrate that these two approaches can determine potential risk areas of a floodplain due to natural hazards and facilitate preparation of emergency action plans. © 2021, The Author(s), under exclusive licence to Springer Nature B.V.
