• Depicting the nature of aquifers using a physical
  model

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

3
Why we should understand groundwater nature?

• Protect it
• Provide safe and clean water
• Manage the use of it
• Prevent depletion

4
How can we understand groundwater

• Understand the soil water relationships
• Through the physical mode

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

6
Methodology

• Use a group of soils in the model such
• Boulders
• Sand

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

8
Boulder test for drawdown

• Photograph of the drawdown
• Figure 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

Boulder and sand for vertical division

Conclusions

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

13
Conclusions

• The contaminant can be controlled by
• Soil type
• Pumping quantity

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

15
Recommendations

• Conduct experiments before stating anything
  regarding groundwater
• Development of the model to improve the depiction
  of groundwater
