Flood Frequency Analysis of Akçay Stream

Özet

It is extremely important to predict floods for planning water systems and reducing flood damage. For the Akçay stream, which is one of the important branches of the Sakarya river , the floods that can be seen at certain time frequencies have been estimated. Normal (Gauss), log-normal and Gumbel distributions have been used in this context. The suitability of the distributions is investigated using Kolmogorov-Smirnov test and log-normal distribution is appropriated. As a result, the 100-year flood discharge is found to be 7,52 m3/s on log-normal distribution.
