36.3. Transmissibility (T)

Try these first

1. 1.

   What is the formula to calculate transmissibility?

   Hint

   It's a simple multiplication.

2. 2.

   If k = 0.04 m/s and b = 10 m, what is the transmissibility?

   Hint

   Multiply the values to find T.

3. 3.

   What does transmissibility measure?

   • Rate of flow through aquifers
   • Amount of water contained in soil
   • Pressure of underground water

   Hint

   Think about water movement.

4. 4.

   True or False: Higher transmissibility always ensures a better aquifer.

   • True
   • False

   Hint

   Consider aquifer performance.

5. 5.

   An aquifer has a coefficient of permeability of 0.06 m/s and a saturated thickness of 12 m. Calculate the transmissibility in m²/day. If the community requires 50,000 m²/day, will this aquifer be able to meet the demand?

   Hint

   Convert the final answer to m²/day after calculating transmissibility.

6. 6.

   A well drawdown test reveals that a well in a low transmissibility aquifer with k = 0.01 m/s and b = 8 m is not yielding sufficiently. Propose a method to improve water extraction from this well.

   Hint

   Consider the physical properties of the aquifer.
