Title

WATER SPREADING IMPACT ON AQUIFER RECHARGE OF THE SOHRAIN- QARECHARIAN PLAIN OF ZANJAN

Pages

  291-300

Abstract

 Declining ground water level and lack of adequate recharge are the most limiting factors for development projects. Knowledge about methods of water spread systems and their effects on ground water resources along with other natural factors influencing the recharge of aquifers is one of the most important activities that could be assessed in managing water spreading and AQUIFER RECHARGE projects. The aquifer in Zanjan plain, in north-west of Zanjan City that is covered by the quaternary coarse material depositions of recent are has suitable ground water that can be recharged by the surface flows through the implementation of artificial recharge projects. In this study, the effect of volume of recharge floodwater in flood spreading station of Sohrain-Qarecharian, Zanjan, on the changes of qanat water delivery located in the spreading area has been investigated and compared with the delivery rate of a control qanat located outside of the area. Ground water level changes in the plain and in some observation wells were surveyed during the period 1995 2002. It was observed that during a 7 year period the water delivery of the qanat located in spreading area was highly affected by the amount of water spreading and showed large changes during the spreading times. However, the control qanat, despite having a larger basin, showed no changes. Ground water table changes in 3 observation wells around the spreading area showed that their levels were not affected by drought and rose about 0.5m due to the artificial recharge of groundwater. Whereas, in the control well, the drop in water table continued during this period and was measured to be about 4.5 m. The data on groundwater table of plain also showed no drop and, actually, rose by about 0.5 meter. Finally, this study showed that artificial recharge of aquifers in wet years can prevent water table from dropping and can lead to sustainable management for overcoming the water deficiency during droughts.
