Study of Transterred Water Effects from Zayanderood to Yazd Aquifer
|Location||21th symposium on geosciences|
|Holding Date||24 May 2008|
The average volume of transferred water from Zayanderood to Yazd-Ardekan basin has been 35 MM3 annually from the bingeing of project achievement. The affection of this project is converted because of two ways 1- the affection of transmission of water itself 2- unsupplying of underground water for domestic use at the same time that should be mentioned as saving water. For above mentioned reason the rate of decreasing water table is changed from 54 Cm to 47 Cm per years.
This transmission had more affection on the basin in some locations especially at the zone of utilization. The importance of subject is clearer when we know that 90 percent of transmitted water is used in Yazd city area. So for this reason the trend of decreasing of water table has changed from 78 Cm to 31 Cm per years. Although several factors could be the cause of this affection but according to this fact that none of other factors has been changed in the period of 1380 to 1382 thus it can seed that decreasing trend of water table is exactly related to Zayanderood water transmition to Yazd province.
