41.4.2. Percolation

Try these first

1. 1.

   What is percolation?

   Hint

   Think about how water moves through a sponge.

2. 2.

   Why is percolation important for groundwater?

   Hint

   Consider the cycle of water and how it affects supply.

3. 3.

   What defines percolation in soils?

   • Upward movement of water
   • Lateral spread of water
   • Downward movement of water

   Hint

   Think about how water settles into the ground after heavy rain.

4. 4.

   Does coarse soil speed up percolation?

   • True
   • False

   Hint

   Remember how sand behaves compared to clay.

5. 5.

   Given a field with sandy soil and another with clay soil, predict how water would percolate in each case after heavy rainfall.

   Hint

   Consider how the texture of each soil type alters water retention.

6. 6.

   Develop a percolation test to evaluate soil for a planned agricultural site, detailing steps and expected findings.

   Hint

   How would soil type influence your testing procedure and interpretation?
