Abstract (2. Language): 
The most common problem in earth dams is abnormal seepage or excessive leakage after the foundation of the dam. When water started to fill the reservoir in Akdeğirmen dam (Afyonkarahisar, Turkey) designed as a zoned earth dam, the seepage developed at the base of the spillway and the downstream of the right bank. The leakage at this dam was investigated by using electrical resistivity and self-potential measurements. The dipole-dipole electrode array with unit electrode spacing of 10 m was used for resistivity imaging survey. An algorithm based on robust inversion technique was used to invert electrical resistivity data. The self-potential data were collected by fixed reference method and interpreted qualitatively by graphs. The investigation results revealed the distribution of strata and the leakage paths along the downstream of the right bank.

Abstract (Original Language): 
Toprak dolgu barajlarındaki yaygın sorun baraj inşasından sonraki olağandışı sızıntı veya aşırı kaçaklardır. Toprak dolgu barajı olarak tasarımlanan Akdeğirmen barajı (Afyonkarahisar, Türkiye) su ile dolmaya başlamasıyla, sağ sahil mansabında ve dolu savak temelinde sızıntı gelişmiştir. Bu barajdaki sızıntı elektrik özdirenç ve doğal potansiyel ölçümleri kullanılarak araştırılmıştır. Özdirenç görüntüleme araştırması için 10 m birim elektrot aralıklı dipol-dipol elektrot dizilimi ve verileri değerlendirmek için robust ters çözüm tekniğini esas alan bir algoritma kullanılmıştır. Doğal potansiyel verileri baza indirgeme ölçü tekniği ile toplanmış ve grafiksel sunum ile nitel olarak yorumlanmıştır. Araştırma sonuçları yeraltı tabaka dağılımını ve sağ sahil mansabı boyunca sızıntı yollarını ortaya çıkarmıştır.
