Abstract:   (220 Views)

Flood control, artificial recharge of aquifers and attempt to optimize the utilization of the natural resources are some of the most important measures in the arid and semi arid zones that occurs by flood spreading projects. At the current study the impact of flood spreading on downstream qanat discharge at Myankooh area of Mehriz (Yazd province) was investigated. To gain this goal after collecting the discharge Statistics from 1997 to 2013, Standard Discharge Index (SDI) was calculated. The amount of flood water entering the aquifer areas and precipitation figures were used to calculate the Standardized Precipitation Index (SPI). The correlation between the SDI and SPI and flood volume was extracted. Also, the operators’ comments were collected by using the designed questionnaire. According to the results, the SDI increased at the same time as wet period and flood spreading time. But the share of each one on this invreasing wasn’t clear. The correlation with SDI and SPI in different qanats was significant (1%) with 12, 6 and 3 months’ delay. Close to 28% operators assessed the project’ impact high, 43% very low and others moderate.
