Abstract

In this study, the Meymeh River was selected with regard to the construction of a reservoir dam in its direction, with the aim of determining the effective factors in decreasing water quality and providing Curative solutions. For this purpose, with field investigations, sampling stations (35 stations) were determined along the path of the river and for one year (96 - 95) monthly at the selected stations measured discharge, EC and Temperature. In the following, after the samples were transferred to the laboratory, were also measured their physical and chemical properties. The results showed that the water quality of the river decreases gradually from the upstream to downstream of the river, due to the arrival of the water of the Sulfur Springs and the Syvol River with an average annual electrical conductivity of 21600 and 77750 µs/cm respectively, the electric conductivity of the river arrives to more than 23,000 µs/cm. Therefore, after the confluence of the Sarkadeh with the Meymeh river, the electrical conductivity of the river Meymeh arrives more than 11,000 µs/cm. To solve this problem, is suggested establishment of channels in the salt zones, Good infrastructure, Construction of tunnels and pipelines to transfer water of the salinity factors to The downstream of Meymeh dam.
