Abstract
Bu çalışmada, Konya ovasında Hooghoudt denklemi kullanılarak paralel dren yöntemi ile toprakların ortalama doygun hidrolik iletkenliği (Ksat) belirlenmiştir. Çalışmada dren boru çapı 0.1 m, derinliği 1.70 m ve uzunluğu 80 m olan, 40 m dren aralığına sahip, 3 dren hattı ve oluklu plastik borulardan oluşan bir pilot deneme alanından elde edilen veriler kullanılmıştır. Zarf malzemesi olarak, dren derinliğindeki toprağın özelliklerine göre belirlenen kum-çakıl karışımı kullanılmıştır. Testlerde, sistemde serbest akış sağlandıktan sonra drenaj çıkışlarındaki debiler ve iki dren orta noktasındaki hidrolik yükler aynı anda ölçülmüştür. Elde edilen veriler değerlendirilerek Konya Ovası’ndaki akiferin geçirgenliğinin 7.282 m² gün-¹, ortalama hidrolik iletkenliğin (Ksat) 2.867 m gün-¹, ve alt ve üst sınırlarının %90 olasılıkla 2.461<Ksat<3.273 m gün-¹ olduğu belirlenmiştir.
In this study, the average saturated hydraulic conductivity (Ksat) of the soils in the Konya plain was determined by the parallel drain method using the Hooghoudt equation. In the evaluations, data was obtained from a pilot trial area with a drain pipe diameter of 0.1 m, a depth of 1.70 m, and a length of 80 m, with 40 m drain spacings, 3 drain lines, and corrugated plastic pipes were used. The sand-gravel mixture determined according to the soil properties at the drainage depth was used as the envelope in the drainage system. In the tests, the drainage flows at the drainage outlets and the hydraulic heights at the midpoint of the two drains were simultaneously measured after free flow was achieved in the system. By evaluating the data obtained, it has been determined that the permeability of the aquifer in the Konya plain is 7.282 m²d-¹, the average hydraulic conductivity (Ksat) is 2.867 m d-¹, and its lower and upper limits are 2.461<Ksat<3.273 m d-¹with 90% probability.
