We get 600 mm rain , and 1200 mm evaporation. Our climate is drought and we don't have almost any water. Do you think in this land , is there enough watershed area?
...37 04 29.46N 37 10 31.47E It is between 2 seasonal little streams.
If you see any land that you think is suitable for a pond and that's maximum 15 miles(birdfly distance) far away from "Gaziantep" city, i will be happy to hear
.
You can see the topografy of the city on this link :
http://www.uydutr.com/topografya/gaziantep For starters, I'm NOT your guy for qualified pond-construction guidance - which certainly isn't my area of expertise. I was simply intrigued by the challenge & ability to remotely assess the site from half-way around the globe; and merely offered my non-professional "concerns" for filling a man-made pond under your region's apparent climate conditions.
Disclures now complete; I think
the alternate coordinates that you provided would offer much better topography for capturing rainfall (compared to the original site). Beyond that, I'm at a loss for providing further guidance due to the numerous factors that should be considered.
I'll include some images of the alternate site below and see if someone can offer any suggestions for you to pursue.
