Abstract

There are numerous springs and wells within the context of this research about the part of northern and
northeastern in The Mandalia Bay which has an important role regarding tourism and agriculture in Turkey’s
Southeastern Aegean coasts. There are an important springs in this basin, as the high discharge with values
Ekinambari springs for 5385 l/s, Savrankoy springs for 4215 l/s, Avsar springs for the 1000 l/s, Sucikti springs
(Karacahisar) to 400 l/s. The change of the total annual flow observations compatible with each other, an
increase was observed in springs of Ekinambari, Savrankoy and Sucikti. The springs group of Ekinambari, is
located from the sea about 10 km away in the alluvium. These springs were at the foot of the hill at various
points at 46 m altitude, different flow rates and temperatures, allochthonous limestone flows from the broken
system. The springs in the investigation area, which was measured in the high current values, of Savrankoy and
Ekinambari springs monthly average current value of resources are examined, the difference between the
current value is less than by months. In this spring waters of high salinity values (0,5 to 36,2‰) was
determined.
In this study were questioned as origin of ground water salinity from deep aquifer formations or from current
sea water? In the case of salinity, in spring waters have occurred on deep towards the karstic levels of
limestones from sea water is saturation. Examined the water was fed by a high level, the transition period is
short and in aquifer in contact with shallow circulating water for a short time is. They could say that mixing
different amounts of surface water were also. Given these results, the most important spring waters for the
region (Savrankoy, Ekinambarı, etc.,) of ground water movement in karstic system pressure and
decreasing/increasing rate of interventions performed in the presence of a seawater can be mentioned.
