Dam flood risk analysis an example of Sakarya Dogantepe dam

Dams, flood prevention, water supply, irrigation, hydroelectric power generation etc. water structures constructed for purposes. Since the reservoirs in the reservoir contain very large volumes of water, the size of the sudden floods that may be caused by collapse is much greater than the size of the floods that may occur due to excessive rainfall. Therefore, they can cause great loss of life and property in case of a possible collapse. The aim of the study is to determine whether the floods that may occur during the demolition of Geyve Doğantepe Pond will reach the Geyve District Center in the downstream region. The HEC-RAS program, which was developed by USACE, was used in the study. As a result of the analysis conducted using the aforementioned program, it was determined that some settlements in the downstream region will be affected by flood. As a result of the analysis, flood propagation maps were formed and the maximum water level and the time of occurrence of these levels were determined.
