What is the main purpose of borehole logging?
A. Monitor groundwater table
B. Record subsurface soil and rock details
C. Determine surface runoff
D. Measure permeability
Answer: Option B
Solution (By Examveda Team)
Borehole logging involves systematic recording of soil and rock strata encountered during drilling to identify geological profiles essential for engineering design.This includes noting changes in color, texture, moisture, and material type.This Question Belongs to Geological Engineering >> Site Investigation And Geotechnical Exploration
