5.6. Selection of Suitable Site

Try these first

1. 1.

   What is catchment yield?

   Hint

   Think about how much rainwater can be collected.

2. 2.

   Name one benefit of narrow gorges for dam sites.

   Hint

   Consider the shape of a gorge.

3. 3.

   What is the primary purpose of assessing catchment yield?

   • To determine water flow
   • To assess ecological impact
   • To ensure enough water storage

   Hint

   Focus on why we need water in reservoirs.

4. 4.

   True or False: Geological stability is unimportant for dam safety.

   • True
   • False

   Hint

   Consider what could happen if the ground is unstable.

5. 5.

   Given a potential dam site with a varied topography, outline how you would assess its suitability based on hydrological and geological factors.

   Hint

   What methods would you use to gather data on rainfall and soil composition?

6. 6.

   Evaluate the potential social impacts of constructing a dam in a densely populated area and propose mitigation strategies.

   Hint

   Consider how the community will be affected and what measures can ease transitions.
