Climatic change in quaterner is one of the most important problems that some of the researchers would like to know about it. There are different methods for researching, but the
geomorphologists try to sort out this fen omen in respect to landforms.
This articel argue about the natural historic of Zayande-Roud and formation of civilization along the bank's. We can conclude that the most important features of this research are as the
following:
- That the lake of Zayande-Roud Dam is the remains of a natural lake and it has never been
part of Karon Basin (to the contrary of Oberlander hypothesis).
- As the result of the breakage of this lake the permanent Zayande-Roud River imerged and
along it,s bank the first signs of civilization spring up.
