Noktasal taşkın frekans analizi: Göksu Nehri ve Kayraktepe Barajı vaka analizi.

The coast of Eastern Mediterranean located on downstream of the Göksu River has been exposed to flood disaster for several times in the past. Many studies in the basin have been carried out to prevent the developing damage and use advantage of the river. One of them is the Kayraktepe Dam which has been on the planning stage for more than thirty years. In this study, the information about historical process of the Kayraktepe Dam will be given and evaluation the flood frequency curves with nonparametric approach based on K nearest neighbors (KNN) in order to serve one of the purposes of the dam will be emphasized. While these results are compared with aforementioned parametric approaches as well as the results of Electrical Power Resources Survey and Development Administration which was responsible for performing initial investigation and planning of Göksu Basin, the applicability of the nonparametric approach will be questioned. Although quantile estimates for 500 years return period was 2363,95 m³/s in past feasibility report, this value descended to 1814,83 m3/s with nonparametric approach. The decreasing of designing dam dimensions is important to reduction both economical and environmental concern. As a result, the study will offer a detailed and a wide range of discussion on the design discharge of the dam. [ABSTRACT FROM AUTHOR]
