Modelling of South Sapanca basin flood inundation maps: Keçi stream sample

Flow and stream level change in time at rivers. When flow and water stream at high quantity/level, stream may flow outside of riverbed. Floods known as hydrological extreme incidents may occur grave economic, ecologic and environmental losses and even loss of life. It's a necessity that hydrological datas to be collected, analyzed with various methods estimated in order to reduce damages to minimum and calculation of environmental losses. For this purpose, flood inundation maps have been calculated with computer modelling of precipitation-flow simulation by using statistical methods for 5, 10, 50, 100 and 500 years of flood repetition flows at Keçi stream sample, south Sapanca basin. In this study, damages and built-in spaces affected by flood detected and some solutions presented in order to reduction/prevention.
