Match the following items in Column I with the corresponding items in Column II:
| Column I | Column II |
|---|---|
| P. Flownet | 1. Soil erosion |
| Q. EI₃₀ Index | 2. Curve number |
| R. Groynes | 3. Equipotential line |
| S. Isobath | 4. Groundwater |
| T. Runoff | 5. River bank |
Options:
(A) P-4, Q-2, R-5, S-3, T-1
(B) P-4, Q-3, R-1, S-5, T-2
(C) P-3, Q-1, R-5, S-4, T-2
(D) P-3, Q-1, R-2, S-4, T-5
Official Answer Key:
C
Step-by-Step Solution & Explanation
Flownet is drawn from intersecting flow lines and equipotential lines ⇒ P-3.
EI₃₀ is the rainfall erosivity index R of the USLE, used in soil erosion estimation ⇒ Q-1.
Groynes are structures projecting into a stream to protect the river bank ⇒ R-5.
An isobath is a contour of equal depth — here, of the water table/aquifer ⇒ groundwater, S-4.
Runoff is estimated by the SCS curve number method ⇒ T-2.
