Abstract

Determination of
spatial distribution of precipitation has an importance in terms of
hydrological applications and water resources assessment. Particularly, the
effects of orography and coastline on precipitation distribution should be
taken into account in mountainous and/or coastal regions. This necessity is
complicated by the limited number of rain gauges which have also a
nonhomogenous distribution. In this study, it is aimed to determine the spatial
distribution of precipitation for the coastal part of the Eastern Black Sea
Region. It can be said that this study is the first in terms of combination of
precipitation distribution on both hillside and coastal part by using two
different approaches. One of these approaches is the water balance that reflects
the precipitation distribution on hillside. The other one depends on the
regression equations which explains the precipitation variability on coastline
and valleys, for the coastal part of the Eastern Black Sea Region.

Ölçümleri Az Olan Kıyı Bölgelerinde Yağışın Yerel Dağılımının Belirlenmesi: Doğu Karadeniz Bölgesi

Abstract

Yağışın alandaki dağılımının belirlenmesi, hidrolojik
uygulamaların ve su kaynaklarının doğru değerlendirilmesi açısından büyük önem
taşır. Özellikle dağlık ve/veya kıyı bölgelerde hem orografiyi hem de kıyı
etkilerini yağışın dağılımını belirlemede hesaba katmak gerekebilir. Bu
gerekliliği, dağlık bölgelerde yağış gözlem istasyonlarının az ve düzensiz
olması zorlaştırır. Bu çalışmada da, orografik yağış özelliği gösterdiği
bilinen ve sınırlı sayıda yağış gözlem istasyonuna sahip Doğu Karadeniz
Bölgesinin kıyı kesimi için yağış dağılımının belirlenmesi amaçlanmıştır.
Çalışma, Doğu Karadeniz Bölgesinin kıyı kesimine ait yamaçlardaki yağış
dağılımının temsilinde su dengesinin, kıyı ve vadilerdeki yağış dağılımının
temsilinde ise regresyon denklemlerinin birleştirilerek kullanılması açısından
bir ilktir.
