Step 1: Understanding the Concept:
We match terms from soil conservation, irrigation, and groundwater hydraulics with their respective physical media, components, or operational parameters.
Step 3: Detailed Explanation:
Let us analyze each pair logically:
1.
Erosivity (A): A measure of the potential of rainfall to cause soil erosion. Thus, it is a property of the
Rainfall. Matches with
(III).
2.
Erodibility (B): The vulnerability or susceptibility of a soil to erosion forces. Thus, it is a property of the
Soil. Matches with
(IV).
3.
Application efficiency (C): The ratio of the water stored in the crop root zone to the water delivered to the field, representing an
Irrigation parameter. Matches with
(V).
4.
Radial flow (D): The horizontal flow of groundwater from all directions towards the cylindrical screen of a pumping
Tubewell. Matches with
(I).
5.
Cone of depression (E): The conical drop in the water table surrounding a pumping well. The overlap of adjacent cones of depression determines the minimum required
Tubewell spacing to prevent interference. Matches with
(II).
This yields: (A) - (III), (B) - (IV), (C) - (V), (D) - (I), (E) - (II).
Step 4: Final Answer:
The correct option is 2, which corresponds to (A) - (III), (B) - (IV), (C) - (V), (D) - (I), (E) - (II).
