After the construction of Torogh Dam in 1984, there was a slump and a high
reduction in underground water level in the upper area of Torogh Riverʹs
detrital fan. This case is very well observable in the hydrograph of wells in
the areas of Khaaje Abaasalt, Ghalʹe Sakhtemaan and Mazraʹeye
Nemooneh. The level of water in these wells has reduced 45, 22 and
21meters respectively in a period of twenty years. Since Toroghʹs detrital
fan has coarse fragments deposits, it has a high permeability and like other
detrital fans, the size of its deposits has reduced from top to the bottom, as a
result, its permeability has reduced as well. The permeability of the
fragments is ranging from 7.2.10.2 in the top part to 2.10.2 meter second in
the base. The reduction of water level has also changed the amount of salts
in the water.
