Question

Consider the following statement for groundwater flow
• The water in confined aquifers is having pressure greater than atmospheric pressure.
• The unconfined aquifer is also known as water table aquifer.
• The unconsolidated type of formation have secondary porosity.
• The perched aquifer is a type of unconfined aquifer.
• Hydraulic conductivity has the dimension of velocity. Choose the correct answer from the options given below:

• A. A, B, C, D Only
• B. A, B, D, E Only
• C. B, C, D, E Only
• D. A, C, D, E Only

Hint:

Important groundwater facts:
• Confined aquifer \(\rightarrow\) pressure greater than atmospheric
• Unconfined aquifer \(\rightarrow\) water table aquifer
• Unconsolidated formations \(\rightarrow\) primary porosity
• Hydraulic conductivity dimension: \[ LT^{-1} \] Memory Trick: \[ \boxed{ \text{“Confined-pressure, Unconfined-water table”} } \]

Answer 1

The Correct Option is B
