  1. بسم الله الرحمن الرحيم Depicting the nature of aquifers using a physical model Mohammad Souliman Sawalha May 2011 SAWALHA

  2. Importance of groundwater • Major source for drinking water • Most reliable source of freshwater • Used for domestic, agricultural and industrial activities • Stored deep in the underground SAWALHA

  3. Why we should understand groundwater nature? • Protect it • Provide safe and clean water • Manage the use of it • Prevent depletion SAWALHA

  4. How can we understand groundwater • Understand the soil water relationships • Through the physical mode SAWALHA

  5. Objective of the Project Simulate • Actual aquifer functionality • Media type influence on groundwater movement • Well operation influence on other wells in action • Movement of contaminants SAWALHA

  6. Methodology • Use a group of soils in the model such • Boulders • Sand SAWALHA

  7. Methodology • Conduct experiments • Boulders test for drawdown • Sand test for recharge nature • Boulders and sand for vertical division • Boulders and sand for horizontal division SAWALHA

  8. Boulder test for drawdown • Photograph of the drawdown • Figure of the drawdown SAWALHA

  9. Sand test for recharge nature • Photograph of the different elevations inside the well and around it • Figure for the recharge nature SAWALHA

  10. Boulder and sand for vertical division • Photograph 1 • Photograph 2 • Photograph 3 SAWALHA

  11. Boulder and sand for horizontal division Video SAWALHA

  12. Conclusions • The water table depends upon • Media type • Recharging conditions • Location with respect to operating well SAWALHA

  13. Conclusions • The contaminant can be controlled by • Soil type • Pumping quantity SAWALHA

  14. Conclusions • Drawdown in water table does not occur all the time a rise may happen • Groundwater system tries to find a condition for balance after a stimuli • Water moves faster in boulders than sand SAWALHA

  15. Recommendations • Conduct experiments before stating anything regarding groundwater • Development of the model to improve the depiction of groundwater SAWALHA

  16. Thank you SAWALHA
