Abstract

Kuraklık,
en önemli doğal afetlerden biridir. Sunulan çalışmanın temel amacı, kuraklık
ölçütü olarak Paylaştırılmış Entropinin (PE) kullanılabilirliğini
araştırmaktır. Bu amaçla, Kuzey Ege bölgesindeki istasyonların yağış gözlem
verilerinden hareketle, Standart Yağış İndeksi (SYİ), ve PE kuraklık indeksleri
belirlenerek karşılaştırılmıştır. Sunulan çalışmada, Kuzey Ege Bölgesinde uzun
süreli yağış verileri olan 29 istasyon ele alınmıştır. Çalışmanın sonuçları,
bir yandan PE yönteminin kuraklık ölçütü olarak kullanılabileceğine ilişkin
sonuçlar verirken; diğer yandan Kuzey Ege Bölgesi için kuraklık döngülerinin
belirlenmesine katkıda bulunmuştur.

Keywords
