Abstract

In the study, variability in referenceevapotranspiration (ET0) from SoutheasternAnatolian Project (GAP) area was investigated withlinear regression method. For the purpose, seasonalET0 time series were formed from monthly referenceevapotranspiration (ET0). The ET0 data sets of threesites showed a statistically significance decreasingtrend while there was upward trend in some seasonsof two sites. But, variation in all seasonal ET0 timeseries of Kilis site was not detected.

Özet

Bu çalışmada, Güneydoğu Anadolu Projesi (GAP) bölgesinde referans bitki su tüketimindeki değişim lineer regresyon yöntemi ile incelenmiştir. Bu amaçla aylık referans bitki su tüketiminden mevsimlik ET0 zaman serileri oluşturulmuştur. İki şehirde ET0 veri kümeleri bazı mevsimlerde artan trend gösterirken, üç şehirde istatistiki anlamda önemli bir azalan trend göstermiştir. Ancak Kilis’de tüm mevsimlik ET0 zaman serilerinde değişim saptanmamıştır.
