25.2.3. Soil Type and Surface Condition

Try these first

1. 1.

   What type of soil retains water longer, clayey or sandy?

   Hint

   Think about the size of the soil particles.

2. 2.

   Does compacted soil have higher or lower depression storage?

   Hint

   Remember the impact of compaction on soil.

3. 3.

   What is the primary soil type that retains water for a longer duration?

   • Sandy soil
   • Clayey soil
   • Loamy soil

   Hint

   Consider how different particles interact with water.

4. 4.

   Compacted soils have higher depression storage than loose soils.

   • True
   • False

   Hint

   Think about how compaction affects water movement.

5. 5.

   If you have 100 mm of rainfall on a field with clayey soil, and the depression storage capacity is 10 mm, how much water will enter the soil?

   Hint

   Start by calculating what is retained and then what runs off.

6. 6.

   Analyze two different sites—with similar rainfall where one site has compacted soil and the other has a loosened surface. What differences in water retention patterns would you expect?

   Hint

   Consider how each type of soil handles water during and after rainfall.
