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

7. Conduct experiments Boulders test for drawdown
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

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

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

13. Soil type Pumping quantity 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
