Abstract :

Qomrood is one of the rivers which has little water and it flows in the central part of Iran. This river flows from northern regions of Zargos Mountains and it joins Qarechi river in Masileh area and it flows to salt lake of Qom in north east of the city of Qom. Qomrood river is 19000 square kilometers and the length of its main branch is estimated to be 288 kilometers. This river flows from south east to north east. The main water of this river is provided by Golpayegan Dam. The main and major length of its region is 3724 meters and its minor length is 810 meters in the exit in Masileh area. Two main Dams of Panzdaheh Khordad dam with 200 million square meters capacity and Golpaygan dam with 46/5 million square meters capacity have been made in front of this river. The existence of agricultural land beside the river causes damages to this river. And the river has been made muddy, and it reduced the quality of the river while river has the least water in summer especially around Bahgherabad Bride is very much polluted. To preserve, and cleaning the Ecosystem of Qomrood river realizing the source of pollution around the river and clarifying the type, and amount of pollution and its entrance to river is very much important. Taking sample in accordance with its flowing and its minor branches, and industrial, and agricultural villages, and cities pollution and making the transportation easy and reaching to these sample making centers in different seasons and these places are selected because of its little distance to these centers of Hydrometers. Approximately, there are 8 to 12 centers in the length of Qomrood river and the amount of BOD5, COD,TURB, TEMP, COND, DO,PH have been tested, and from the objects (IDS) in Emamzadeh Abdullah (a.s) Qaleh cham , Khalajabad Bridge, receive the majority of these objects also the main dark TURB is in Qalehcham region Fara asphalte Bridge, Khalajabad Bridge Hamvarlakhah is more than the other centers and sand washing units cause these activities in this regions. Leading the water to panzdaheh khordad Dam and the water is influenced by salty lands menwhile entering the dirty water of Ro system to be cleaned to be cleaned and in Enghelab Bridge of this one of the reasons of increasing the EC of the water of the river. In the studies it has been clarified that agricultural, industrial, man made, and city pollution has made the Ecosystem of the river dirty. Entrance of pollution to the river causes the increase of chemicals and decrease oxygen of water, and it caused the death of water creatures specially fishes.
