This lake plays a key role in an<br />environment of the northwest of Iran. In the last decade, construction of several dams on the rivers<br />discharging to the lake has caused water level decrease of the lake and as a result adverse effects on<br />the lake environment. In this research, by using Mike 3D model, water level and salinity pattern of the<br />Urmia lake have been predicted. Inflow decrease to the lake was considered to be both gradual and<br />instantaneous. Salinity and water level of the lake during coming years were also simulated.<br />According to the results obtained, reduction of inflow to the lake has caused decrease of water level in<br />the lake. This decrease will cause atrophy of major part of the lake. Water level reduction of the lake<br />varied from 1.5 to 2.5 meter depending on the amount of inflow diverted and used upstream.<br />Furthermore, several scenarios have been investigated to improve the lake condition. These results<br />have also shown that creating an extra opening in the west of causeway, does not have any significant<br />effects on the salinity pattern of the lake. https://jhyd.iha.ir/article_85490_65a38dece85e0afa021fa7fac55eaa3d.pdf
