Section 4: Soil and Water Conservation Engineering
Soil Mechanics
Subtopic: Engineering properties of soils
Question Statement:
Match the soil and fluid properties in Column I with their physical definitions in Column II:
| Column I | Column II |
|---|---|
| P. Hydraulic Conductivity | 1. Upper limit of moisture available to plant |
| Q. Permeability | 2. All soil pores filled with water |
| R. Viscosity | 3. Soil capillarity |
| S. Surface Tension | 4. Property of fluid and soil |
| T. Saturation Capacity | 5. Property of the medium |
| U. Field Capacity | 6. Internal friction resisting flow |
Options:
(A) P-4,Q-5,R-6,S-3,T-1,U-2
(B) P-5,Q-4,R-6,S-3,T-2,U-1
(C) P-4,Q-5,R-3,S-6,T-2,U-1
(D) P-4,Q-5,R-6,S-3,T-2,U-1
Official Answer Key:
D
Step-by-Step Solution & Explanation
Hydraulic Conductivity (P) depends on BOTH fluid and medium properties (4). Permeability (Q) is an intrinsic property of the medium alone (5). Viscosity (R) is the internal friction resisting flow (6). Surface Tension (S) governs soil capillarity (3). Saturation Capacity (T) is when all pores are water-filled (2). Field Capacity (U) is the upper limit of moisture available to the plant (1).
