Lysimeter is an instrument used to measure the following process(es):
Show Hint
- Evaporation
- Infiltration
- Evapotranspiration
- Deep percolation
The Correct Option is C, D
Solution and Explanation
A lysimeter is primarily used to measure evapotranspiration, which is the sum of evaporation from the soil and transpiration by plants. It is also used to measure deep percolation, which is the downward movement of water beyond the root zone.
- (A) Lysimeters do not solely measure evaporation; they measure evapotranspiration, which includes both evaporation and transpiration.
- (B) Lysimeters do not directly measure infiltration, which refers to water entering the soil from the surface.
- (C) Correct. Lysimeters are designed to measure evapotranspiration.
- (D) Correct. Lysimeters also measure deep percolation, the movement of water below the root zone.
Thus, the correct answers are (C) and (D).

- Apple slices are dried from a moisture content of 65% (dry basis) to 10% (dry basis) in a hybrid solar dryer under falling rate period. The apple slices have a drying rate constant of \( \frac{1}{104} \) minute\(^{-1}\). Considering an equilibrium moisture content of 2% (dry basis), the time required for drying is _________ minutes.

- The minimum bearing capacity of a soil under a given footing occurs when the groundwater table location is at:
- For an anisotropic soil, permeability in $x$ and $y$ directions are $k_x$ and $k_y$ respectively, in a two-dimensional flow. The effective permeability ($k_{eff}$) for the soil is given by:
- Two footings (one is circular and the other is square) are founded on the surface of a purely cohesionless soil. The diameter of the circular footing is the same as that of the side of the square footing. The ratio between ultimate bearing capacity of circular footing to that of the square footing (using Terzaghi equation) will be:
- To have zero active pressure intensity at the top of a wall in a cohesive soil, one should apply a uniform surcharge intensity of: (Where $C =$ cohesion and $\alpha =$ angle of failure plane with major principal plane)
