Surveying and Levelling
Subtopic: Contouring
Question Statement:
Match the contour characteristics in Column-I with the corresponding ground features in Column-II:
| Column-I | Column-II |
|---|---|
| 1) Uniformly spaced contour lines | P) Flat ground |
| 2) Widely spaced contour lines | Q) Steep ground |
| 3) Closely spaced contour lines | R) Hill |
| 4) Close contours, higher values inside | S) Uniform slope |
Options:
(A) 1-P,2-R,3-S,4-Q
(B) 1-S,2-P,3-Q,4-R
(C) 1-Q,2-S,3-P,4-R
(D) 1-S,2-Q,3-P,4-R
Official Answer Key:
B
Step-by-Step Solution & Explanation
Standard contouring interpretation: uniformly spaced contours indicate a uniform slope (S); widely spaced contours indicate flat ground (P) (small elevation change over distance); closely spaced contours indicate steep ground (Q); a series of closed contours with increasing value toward the centre indicates a hill (R). This gives 1-S, 2-P, 3-Q, 4-R. Answer: (B).
