Özet:

 

In this research, a stable environmental isotope study was  carried out from an analysis of water samples collected from rainfall,  runoff (total discharge), springs (subsurface flows) and wells  (groundwater) between 1996 and 2000.  The research site was the Güvenç  Basin located near Yenimahalle-Ankara with a drainage area of about  16.125 km2.  The aim of the study was to investigate the  rainfall-runoff relationship for the Güvenç Basin using the stable  isotope method in the separation of hydrographs.  Recorded total  discharge hydrographs are separated into their components using  isotopes (oxygen-18, deuterium) contents.  Among these samples, unit  hydrographs from 2 single-peaked storm hydrographs were derived using  both isotope and graphical (Barnes semi-log) methods and the derived  unit hydrographs' peaks were compared.  It was found that the  contribution of subsurface flow originating from various sublayers of  the basin is important in hydrograph separation when using the isotope  method of approach.
