A hydrogeological investigation of the Yeþilyurt (Isparta-Sütçüler) plain

Investigation area is almost 10 km in the north-west of Sütçüler country of Isparta and covers 60 km2 area. Firstly, detailed geological and hydrological investigation of Yeþilyurt Plain surface drainage area has been performed. Long term monitoring and analyses have been done for direction of hydrological investigation. An isohiyetal map was prepared for the investigation area. Water table maps were drawn by means of deep and shallow boreholes in the plain and flow direction was determined (October 2000). Water which was collected at boreholes was chemically analyzed to determine the characteristic of water for domestic use, irrigation and industrial purposes. In order to achieve this, the anion and cation concentrations, ionization abilities ionic activity, calcite dolomite sulphate saturation indexes and the partial pressures of dissolved CO2 were calculated and the results were interpreted. In addition, water has been classified according to chemical contend and use purpose by means of Wilcox, USA Salinity Laboratory, Piper and Schoeller diagrams and similarities in the origins of waters were investigated. During the study, a groundwater budget of Yeþilyurt Plain was prepared in the light of obtained data and optimum output of groundwater has been calculated.

Yeþilyurt (Isparta-Sütçüler) ovasýnýn hidrojeoloji incelemesi

Ýnceleme alaný Isparta-Sütçüler ilçesinin yaklaþýk 10 km kuzeybatýnda yer alýr ve 60 km2’lik bir alaný kapsar. Ýnceleme alanýnda ilk olarak Yeþilyurt Ovasý yüzey drenaj alanýnýn ayrýntýlý jeoloji ve hidrojeoloji incelemesi yapýlmýþtýr. Hidrojeoloji çalýþmalarýnýn amacý doðrultusunda, uzun süreli gözlem ve analizler yapýlmýþtýr. Ýnceleme alaný ve yakýn çevresinin eþ yaðýþ haritasý hazýrlanmýþtýr. Ovada bulunan sýð kuyular ve sondaj kuyularý yardýmýyla deðiþik dönemlere ait yeraltý su tablasý haritasý çizilerek yeraltý suyu akým yönü belirlenmiþtir. Su kimyasý çalýþmalarýnda, sondaj kuyularýndan alýnan su örneklerinin analizlerinden içme, sulama ve endüstride kullaným özellikleri belirlenmiþtir. Bu amaçla sularýn anyon ve katyon daðýlýmlarý iyonlaþma güçleri, iyon etkinlikleri, kalsit-dolomit-sülfat doyma endeksleri ve karbondioksit gazý kýsmi basýnçlarý hesaplanarak sonuçlar irdelenmiþtir. Ayrýca Wilcox, ABD tuzluluk laboratuvarý, Piper ve Schoeller diyagramlarý ile kimyasal olarak ve kullaným amaçlarýna göre sýnýflamalarý yapýlarak köken benzerlikleri araþtýrýlmýþtýr. Çalýþma süresince elde edilen verilerin ýþýðý altýnda Yeþilyurt ovasýnýn yeraltý suyu beslenimi hesaplanarak, emniyetli çekim hesaplanmaya çalýþýlmýþtýr.
