Abstract:

 Groundwater provides most of the freshwater needs such as drinking, irrigation and industry. As a result of increasing population, urbanization and industrialization, groundwater resources are faced with the risk of decreasing and pollution. In addition, exploited usage of irrigation water from groundwater during agricultural activities causes the formation of sinkholes. For this reason, Konya in Türkiye, having a lot of agricultural activities and common sinkhole formations, was chosen as the study area. This research utilized the analytical hierarchy process AHP, a type of multi-criteria decision-making analysis, to assess the groundwater potential in Konya, Türkiye. For this purpose, land use, slope, rainfall, topographic wetness index, drainage density, elevation, plan curvature, profile curvature and stream power index thematic maps were created, and their weights were determined with AHP. Groundwater potential map GWPM was produced by overlay analysis in GIS environment. The GWPM was validated by comparing it with the groundwater zones GWZ map given in the report of Konya Closed Basin Management Plan project. As a result of the validation process, the accuracy value was found to be 0.87.

 Yeraltı suyu, içme, sulama ve sanayi gibi tatlı su ihtiyaçlarının çoğunu karşılar. Artan nüfus, kentleşme ve sanayileşme sonucunda yeraltı suyu kaynakları azalma ve kirlenme riskiyle karşı karşıyadır. Ayrıca tarımsal faaliyetler sırasında yeraltı suyundan sulama suyu kullanılması, obruk oluşumuna neden olmaktadır. Bu nedenle, Türkiyede çok sayıda tarımsal faaliyetin gerçekleştiği ve yaygın obruk oluşumlarının bulunduğu Konya, çalışma alanı olarak seçilmiştir. Bu araştırmada, Türkiyenin Konya kentindeki yeraltı suyu potansiyelini değerlendirmek için çok kriterli karar verme analizi türlerinden biri olan analitik hiyerarşi süreci AHP kullanılmıştır. Bu amaçla arazi kullanımı, eğim, yağış, topografik ıslaklık indeksi, drenaj yoğunluğu, yükseklik, düzlem eğriliği, profil eğriliği ve akarsu güç indeksi tematik haritaları oluşturulmuş ve ağırlıkları AHP ile belirlenmiştir. Yeraltı suyu potansiyeli haritası GWPM, CBS ortamında bindirme analizi ile üretilmiştir. GWPM, Konya Kapalı Havza Yönetim Planı projesi raporunda verilen yeraltı suyu bölgeleri GWZ haritası ile karşılaştırılarak doğrulanmıştır. Doğrulama işlemi sonucunda doğruluk değeri 0.87 olarak bulunmuştur.
