Question:
The most important geological requirement for a dam foundation is
The most important geological requirement for a dam foundation is
Show Hint
An ideal dam foundation should have
\[
\boxed{
\begin{aligned}
&\text{High strength}\\
&\text{Low permeability}\\
&\text{Minimum joints and faults}
\end{aligned}
}
\]
Updated On: Jul 23, 2026
- Thick soil cover
- High strength and low permeability of rocks
- High porosity
- Steep slope
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A dam foundation should be strong enough to support the dam and have low permeability to minimize seepage.
High-strength, sound, and impermeable rock provides stability and prevents excessive leakage.
Hence,
\[
\boxed{\text{High strength and low permeability of rocks}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
