Kayaçların gözenekliliği ve geçirgenliği gibi hidrojeoloji için önemli olan jeolojik oluşum özelliklerinin çoğu elektriksel iletkenlik ile ilişkilidir. Bu sebeple, jeofizik arama tekniklerinden elektrik özdirenç yöntemi yeraltı suyu araştırmaları için etkilidir. Özdirenç yöntemlerinden düşey elektrik sondajı (DES) yöntemi, su taşıyan oluşumun kalınlığını ve derinliğini belirlemek için kullanılmaktadır. Diğer bir özdirenç yöntem ise daha geniş alanlarda daha hızlı ve sağlıklı ölçüm almayı sağlayan çok-elektrotlu sistemleri kullanan elektrik özdirenç tomografidir (EÖT). Bu çalışmada, Afyonkarahisar-Emirdağ (Karaağaç) bölgesindeki muhtemel yeraltı suyu bulunduran akifer yapılar, DES ve EÖT yöntemleri kullanılarak araştırılmıştır. 7 istasyonda DES verilerinin ve 4 profilde EÖT verilerinin değerlendirilmesi ile, çalışma alanındaki muhtemel yeraltı suyu içeren akifer yapıların dağılımı belirlenmiştir. Yeraltı suyu sağlamada farklı derinliklerdeki çakıllı birimler ve kireçtaşı iyi akifer özellik göstermektedir.

INVESTIGATION OF EMİRDAĞ-KARAAĞAÇ UNDERGROUND WATER POTENTIAL WITH ELECTRICAL RESISTIVITY METHODS

Öz

Many of the geological formation properties important to hydrogeology, such as the porosity and permeability of rocks, are related to electrical conductivity. Therefore, one of the geophysical exploration techniques, the electrical resistivity method is effective for groundwater exploration. One of the resistivity methods, the vertical electrical sounding (VES) method is used to determine the thickness and depth of the water-bearing formation. Another resistivity method is electrical resistivity tomography (ERT), which uses multi-electrode systems that provide faster and more reliable measurements over larger areas. In this study, aquifer structures that contain possible groundwater in Afyonkarahisar-Emirdağ (Karaağaç) region were investigated using VES and ERT methods. By evaluating VES data in 7 stations and ERT data in 4 profiles, the distribution of aquifer structures containing possible groundwater in the study area was determined. Gravel units at different depths and limestone show good aquifer properties in providing groundwater.
