Precipitation in Türkiye by process of hydrological cycle is quite uneven,
Annual mean precipitation in long term is 643 mm,
Minimum average in drought period is 525 mm,
Maximum average in wet period is 800 mm, Fluctuation from average occurs is about
20% in Türkiye.

TÜRKİYE’S ANNUAL AVAILABLE TÜRKİYE’S ANNUAL AVAILABLE WATER POTENTIAL IS VARIABLEWATER POTENTIAL IS VARIABLE
In wet period : 135 Billion m3
In drought period : 90 Billion m3
Difference : 45 Billion m3
This case indicates 50% fluctuation. It is necessary that water demand in drought
period should be satisfied by 50% less than that of wet period.

TÜRKİYE IS NOT A WATER RICH TÜRKİYE IS NOT A WATER RICH COUNTRYCOUNTRY
Total Available Water Volume : 112 Billion m3
Türkiye’s Population : 70,6 Million Water Availability Per Capita : 1.600 m3/year These values indicate that Türkiye is
regarded as a “water stress” country.

For that reason;To use water cautiously, To avoid using water excessively,To use less water consuming technologies
in irrigation and in daily life is important.
Besides, it is necessaryTo avoid polluting scare water resources.

IMPORTANCE OF DAMS
In Türkiye;
Dams are necessary so as to mitigate the impacts of droughts and floods resulted from climate change. The number of Dams constructed according to ICOLD standard is 592.
Active storing capacity of dams in operation is 66 billion m3.

Water needs can only be satisfied if water resources are properly managed.
To this end, three precautions are significant; Increasing water supply Decreasing water demand Protection water quality
