Abstract
The lake situation and morphometry, climatic conditions, water balance and level, hydrology and hydrochemistry of lake Qarun were investigated.
Salinity proved to be the most important factor affecting the lake water. Annual changes in salinity of the lake water were recorded. In 1906, the salinity ranged from 10.65 and 11.26‰, while in 1974–1976 it reached 30.9–34.5‰.
The physico-chemical properties of the lake change greatly owing to climatic and anthropological factors.
