Try these first

1. 1.

   What is the main purpose of subsurface drainage systems?

   Hint

   Consider what happens when there is too much water.

2. 2.

   Name one type of subsurface drainage system.

   Hint

   Think of the materials used underground.

3. 3.

   What is tile drainage used for?

   • To collect surface water
   • To remove excess water from the root zone
   • To increase soil salinity

   Hint

   Think about the purpose of subsurface water management.

4. 4.

   Mole drainage is particularly effective in which type of soil?

   • True
   • False

   Hint

   Consider the advantages of mole drainage.

5. 5.

   You are tasked with designing a subsurface drainage system for an agricultural field impacted by flooding. Assess the soil types present and recommend a specific type of drainage solution, detailing the layout.

   Hint

   Analyze the effectiveness of each option for varied soil types.

6. 6.

   Discuss the long-term impacts of subsurface drainage on local water tables and soil structure. What could be potential environmental consequences?

   Hint

   Think about how drainage systems alter natural water flows.
