Gerek artan nüfus gerekse sanayide hızlı ilerleme
suya olan ihtiyacı son derece önemli hale getirmiştir. Bu yüzden eldeki su
kaynaklarının optimum kullanılması ve yeni su kaynaklarının ortaya çıkarılması
gerekliliği, planlama çalışmalarının en önemli konularından biri haline
gelmiştir. Ancak çeşitli şartlardan dolayı oluşan ve varlığı pek çok bilim
adamı tarafından dile getirilen küresel iklim değişikliği bu planlamanın
yapılmasını zorlaştıran etmenlerdendir. Bu yüzden iklim değişikliği ve iklim
değişikliklerinin mevcut su kaynaklarını etkileyip etkilemediği sorusu
irdelenmeli ve kaynakların gelecekteki durumlarını nasıl etkileyeceği
araştırılmalıdır. Bu çalışmada iklim değişikliğinden en çok etkilenen
bölgelerden birisi olan ve Afrika’da bulunan Somali’nin Kuzeyindeki Somaliland
bölgesindeki aylık ve yıllık yağış verilerinin trendleri irdelenmiştir. Bu
irdelemede Mann-Kendall trend analizi, Şen grafik testi, Şen grafik testini baz
alan ve Saplıoğlu tarafından teklif edilen istatistiksel method kullanılmıştır.
Çalışmada bölgenin trendinin araştırılmasının yanı sıra trend testlerinin
benzerlikleri ve farklılıkları da irdelenmiştir.

Both the population increase and the rapid advance in the industry have
made the need for water very important. Hence the optimum usage of available
water resources and the necessity for uncovering new water resources have
become the most important issues of planning exercises. But, the global climate
change which is occured because of various conditions and expressed by many
scientists is one of the factors that makes this planning difficult.  So the climate change and the question of
whether climate change affect the available water springs  or not must be inquired and also how it
affects the water availability of the springs in the future must  be investigated. In this study, monthly and
annual rain fall data was examinated in the region of Somaliland where is
placing on the Northern part of Somalia in Africa's one of the most affected
regions. In this study, Mann-Kendall trend analysis, Sen's graphic test and the
statistical method based on Sen's graphic test that is proposed by Saplioglu
are used. In the study, the trend of the region was investigated and trend
tests compared.
