HEC-RAS Model of Kahramanmaras Domuz (Bogaz) Stream Interception Channel

Water, which is the source of life for living things, causes serious loss of property or life when it is not controlled. Additionally, the planned usage of water is of great importance nowadays when we feel the effects of global warming. One of the disasters, flood formation may be human or nature-originated. When a river forms flood, it causes severe damage to agricultural land, infrastructure facilities, people's social and economic life, settlements in the environment. Water resources management plays an important role in the development of a country's socio-economic situation. Channels are used to prevent flood risk and also to ensure that the water moves from source to need. It is possible to design open channels which are modeled in trapezoid, rectangular, semi-circle and triangular shapes in HEC-RAS program. In this study, the calculations of the flood channel project were modeled by HEC-RAS program and the results were compared between project results. Aim of this project is to protect from the harm financial and emotional damage caused by flood in 6-7 streets of Kahramanmaraş province's Oniki şubat district center. The agreement between the results using Mockus and the rational method and the HEC-RAS results was examined. Domuz (Boğaz) stream interception channel; the water depths and speeds that will form along the channel were calculated with the help of HEC-RAS. As a result of the study, it was observed that the results of the Project and model are very compatible with each other.
