33.4.2. Hydraulic Head

Try these first

1. 1.

   What are the three components of hydraulic head?

   Hint

   Think about the forms of energy in water.

2. 2.

   Which component of hydraulic head is usually considered negligible?

   Hint

   It's often ignored in calculations.

3. 3.

   What makes up hydraulic head?

   • Pressure head
   • Elevation head
   • Velocity head
   • All of the above

   Hint

   Consider the components we discussed.

4. 4.

   True or False: The velocity head is a significant factor in groundwater calculations.

   • True
   • False

   Hint

   How often do we ignore it in practice?

5. 5.

   If the elevation head of groundwater in an aquifer is 30 meters and the pressure head is 15 meters, what is the total hydraulic head?

   Hint

   Add both heads together to find total potential energy.

6. 6.

   How might a decrease in elevation head due to extended drought conditions influence groundwater pressure and flow rates?

   Hint

   Consider the relationship between height and pressure.
