During site selection for a dam, why is joint spacing in bedrock important?
A. Affects temperature variation
B. Controls rock color
C. Influences seepage and stability
D. Determines vegetation type
Answer: Option C
Solution (By Examveda Team)
Joint spacing controls rock permeability and mechanical strength.Closely spaced joints may increase water seepage and reduce foundation stability.This Question Belongs to Geological Engineering >> Engineering Geology For Construction
