Wilcoxon Testi ve Saçılma Diyagramı Kullanılarak Hidrometeorolojik Verilerin Trend Analizi

Water scarcity is becoming increasingly widespread due to the increasing world population and the effects of climate change. This situation makes the management of water resources more critical. This study includes the use of different methods for trend analysis of precipitation measurements, which are hydrometeorological data, in order to understand the effects of climate change and the comparative examination of the results of these methods. The Mann-Kendall (MK) test, Wilcoxon test and Şen's Innovative Trend Analysis (ITA) methods are the main tools of this study. This study has carried out a detailed trend analysis using precipitation data obtained from eight different hydrometeorological stations located on the Aegean and Mediterranean coasts of Turkey. These analyses were carried out on maximum precipitation data measured for 30 minutes, 60 minutes and 120 minutes. As a result, it was determined that there was a general significant increase in annual precipitation in these regions under the influence of the Mediterranean climate.
