Türkiye’deki 2007 ve 2013 Yılı Kuraklıklarının NOAH Hidrolojik Modeli ile İncelenmesi

Abstract

Ülkemizde ve dünyada verdiği zararlar açısından doğal afet olarak nitelendirilen kuraklığın analizi ve sonucunda niteliklerinin (süre, şiddet, etki alanı) belirlenmesi, bu doğal afetin etkilerinin daha iyi anlaşılması ve azaltılması ve erken tahmininin yapılabilmesi açısından çok kritiktir. Bu çalışmada, Türkiye’deki kuraklık analizi için hem hidrolojik modelden elde edilen toprak nemi değeri hem de uzaktan algılama ile elde edilen bitki örtüsü indeksi kullanılmıştır. Kuraklık çalışmalarında yaygın olarak kullanılan bu parametrelerin kullanımı ile 2000-2014 dönemi incelenmiş ve özellikle 2007, 2013 yıllarındaki kuraklığın detaylı analizi yapılmıştır.

Analysis of the 2007 and 2013 Droughts in Turkey by NOAH Hydrological Model

Abstract

Analysis of drought, which is classified as a natural disaster, is globally considering the damage it gives. As a result detection of its characteristics is essential for understanding and reducing the effects of this natural disaster and for imminent prediction. In this study, soil moisture estimates obtained from NOAH hydrological model and normalized difference vegetation index obtained from MODIS observations are used to analysis the recent droughts in Turkey. With the utilization of these parameters that are commonly used in drought studies, years 2000-2014 have been examined and a detailed analysis of the drought particularly in the years 2007, 2013 has been carried out.
