Abstract
The parameters which are used in the
determination of the aquifer potential vary according to the location and time
because of the random nature of the underground geological layers. In the
settings which are assumed as homogeneous and isotropic, these parameters can
be determined on average as a single value, using simple mathematical models,
which are based on the assumptions. On the other hand, if the aquifer is
heterogeneous and anisotropic, as a result of the analysis, aquifer parameters
with different values at each special location and time are obtained. In this
study, the exceedance probabilites of the different parameter values, which
were found by the Şen curve matching method, were determined and the aquifer
potential was evaluated according to various risk levels. The professional and
based-on-experience evaluation of the model graphs that were set on the
specific exceedance probabilities instead of the classical analytical and
numerical approaches is seen more meaningful once the aquifer parameters that
were found using the classical methods for the field of study is compared to
the results that belong to this study.

Abstract
Yeraltı jeolojik tabakaları genelde rastgele
yapıda olduğundan, akiferlerin potansiyelinin belirlenmesinde kullanılan
parametreler konum ve zamanla değişir. Tektür (homojen) ve tekyönlü (izotrop)
kabul edilen ortamlarda, bu parametreler varsayımlara bağlı basit matematik
modeller yardımıyla ortalama olarak tek bir değere sahiptir. Buna karşın akifer
ortamının çok tür (heterojen) ve çok yönlü (anizotropik) olması durumunda,
analizler sonucu konum ve zamanla farklı değerlere sahip akifer parametreleri elde
edilir. Bu çalışmada Şen eğim eşleştirme yöntemi ile bulunan akifer parametrelerinin
farklı değerlerinin aşılma olasılıkları belirlenerek, çeşitli risk seviyelerine
göre akifer potansiyeli değerlendirilmiştir. Çalışma alanı için klasik
yöntemler kullanılarak bulunan akifer parametreleri ile, bu çalışmaya ait
sonuçlar karşılaştırıldığında, klasik analitik ve sayısal yaklaşımlar yerine
belli aşılma olasılıkları üzerinden kurulan model grafiklerinin profesyonel ve
tecrübeye dayalı değerlendirilmesinin sonuçlarının daha anlamlı olduğu
görülmektedir.
