Abstract

Floods shows an increase both in number and in terms of damages they cause in tropical climates as well as in Turkey which is not located in tropical region. With the increasing population density and unplanned urbanization, life and property losses become inevitable as a result of these floods. In this study, the flood analysis of the section between the beginning and the end of the Sünlük District settlement located on the border of Karadere Stream in the Mustafakemalpaşa District of Bursa Province was assessed. The planning works of the Sünlük Dam on the Karadere Stream, which is intended to provide drinking water and industrial water to the Mustafakemalpaşa and Karacabey Districts of Bursa Province, are continuing by the 1st Regional Directorate of State Hydraulic Works of Turkey (DSI). Flood areas were determined with the help of the HEC-RAS (Hydrologic Engineering Centers River Analysis System) software and applying the Q1000, Q10000 and QMMF (probable maximum flood) flood return period flow rates at the Karadere Stream which obtained from the dam planning studies. It was concluded that the damage caused by QMMF can reach up to 1000000 TL once flood occur.
