Abstract

The aim of this research is to analyse precipitation and investigate drought conditions by using long-term climate data obtained from the General Directorate of Meteorology. Using the data obtained in the study, precipitation analysis was performed using the HydroTSM package in the R program for the 1970-2022 time period of the Çanakkale central meteorological station and drought analysis was performed according to the standard precipitation index method. With the time series obtained because of these analyses, precipitation and drought data for many years were examined. Daily, monthly, annual and seasonal time series of precipitation were generated and it was determined that precipitation fluctuates irregularly according to the data obtained. Drought analyses were calculated at 3, 6, 12, 24, 36-month time intervals. It was determined that Çanakkale province experienced significant dry periods between 1970 and 2022. According to the results, it was determined that arid and mild arid distribution was more predominant, while humid and semi-humid periods were experienced. The years with the highest severity of drought are 1997, 2009 and 2020. In addition, as the time period of the analyses increases, drought severity and total drought periods are almost similar. Fluctuations in the precipitation regime and drought conditions determined for Çanakkale province were evaluated within the framework of agricultural water management and water resources planning.

Çanakkale İlinin Uzun Yıllar İklim Verilerine Bağlı Kuraklık Analizi

Abstract

Bu araştırmada, meteoroloji genel müdürlüğünden elde edilen uzun yıllar iklim verileri kullanılarak yağış analizi yapılarak ve Çanakkale ili için kuraklık durumu belirlenmeye çalışılmıştır. Çalışmada elde edilen veriler kullanılarak Çanakkale merkez meteoroloji istasyona ait 1970-2022 zaman diliminde R programında HydroTSM paketi kullanılarak yağış analizi yapılmış ve standart yağış indisi yöntemine göre kuraklık analizi yapılmıştır. Bu analizlerin sonucunda elde edilen zaman serileriyle uzun yıllara yayılan yağış ve kuraklık verileri incelenmiştir. Yağışların günlük, aylık, yıllık ve mevsimsel zaman serileri oluşturulmuş elde edilen verilere göre yağışların düzensiz bir dalgalanma meydana getirdiği tespit edilmiştir. Kuraklık analizinde ise 3, 6, 12, 24, 36 aylık zaman aralıklarıyla hesaplanmıştır. Çanakkale ili için 1970-2022 yılları arasında önemli kurak dönemlerin yaşandığı tespit edilmiştir. Sonuçlara göre kurak ve hafif kurak şeklindeki dağılım daha ağır basarken nemli ve yarı nemli dönemlerinde yaşandığı belirlenmiştir. Kuraklığın şiddetinin en fazla olduğu yıllar 1997, 2009 ve 2020 yıllarıdır. Ayrıca analizlerin zaman periyodu artıkça kuraklık şiddeti ve toplam kuraklık süreleri hemen hemen benzerlik göstermektedir. Çanakkale ili için tespit edilen yağış rejimindeki dalgalanmalar ve kuraklık durumu tarımsal su yönetimi ve su kaynaklarının planlanması çerçevesinde değerlendirilmiştir.
