Managing of the agriculture water consumption to meet the environmental flows of the Lake Urmia during the droughts

The Lake Urmia has been suffering a sharp decline in its water surface and level in recent years. Previous reports declared the surface of the lake which is about 6100 square kilometers and has the level of about 1278 meters under the water surface (Eimanifar and Mohebbi, 2007). But recent reports has reported that these values have changed a lot and are less than what was indicated before and it is now about 2000 square kilometers and 1270 meters height, respectively (Morid et al., 2012). In this regard, the problem can be solved with two different approaches: entering new water resource by means of inter-basin transfer of water (first approach) and the internal basin resource consumption management (second approach).
