Qualitative Sampling and Limnological Study of Lake Urmia

درباره پرژوه

Since, National park Urmia is under threat to be died and depletion, in the recent years Iran Water and Power Resources Development Company has put this matter in its priority to collect sufficient and comprehensive data for next steps to restore Lake Urmia. Asarab with cooperation of Norwegian consulting company of AKVA PLAN-NIVA, has performed the monitoring program of the lake. It should be noted that, it was the first time that an extensive monitoring program has been accomplished systematically. In this monitoring programme, physical and chemical qualitative and quantitative parameters, different pollutants such as heavy metals and limnological parameters were analysed, map of different vegetation types and distribution of birds in Lake Urmia, main rivers entering the lake and southern wetlands were prepared for this project. Sampling has been done for one year, monthly, and the gathered data were analyzed. After that, a report of sampling results was presented for EIA and modelling of water conveyance from Caspian Sea to the lake Urmia and was delivered to Aban Pajooh and AKVAPLAN-NIVA. Spontaneously, sampling and monitoring of Kanisib Dam, the rivers entering the dam, effluent of Piranshahr have been performed by Asarab Co. then various parameters of this dam are analysed too, therefore, quality of entering water from Zab area is considered in modelling of Lake Urmia. With the results of this model, environmental impacts of such projects were investigated and analysed. The results of these studies were published in the book of Lake Urmia.
