Study of Sediments Water Resources System of Zayanderud Dam through Area increment and Area reduction Methods, Isfahan Province, Iran.

Zayandehrud damʹs lake with the capacity of 1.6* 109 CM is located 115 Km from Isfahan city at the center of Iran. The dam adopts water resources from Zayandehrud River which originates from western hill slopes of Isfahan Province.
