Question Statement:
A bench terrace sloping inward toward the hill slope with a drain along the toe is specifically designed for:
Options:
(A) Heavy rainfall areas to intercept runoff and convey it safely away from the fragile terrace riser
(B) Extremely dry desert regions with zero rain
(C) Mechanized combined harvesting of wheat on flat plains
(D) Preventing wind erosion only
Answer Key:
A
Step-by-Step Solution & Explanation
Inward-sloping bench terraces direct excess runoff to a protected longitudinal drain at the hill toe, protecting the outer embankment riser from slippage.
