Question

The infiltration rate after the soil profile becomes saturated is called:

• A. Initial infiltration rate
• B. Instantaneous infiltration rate
• C. Basic infiltration rate
• D. Hydraulic conductivity of soil

Hint:

Initial infiltration rate \(>\) Basic infiltration rate.
Basic infiltration rate is the steady-state rate.
Also called the ultimate infiltration capacity.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Infiltration is the process of water entering the soil.
The rate changes over time.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the types of infiltration rates.

Step 3: Detailed Explanation:
Initial infiltration rate is the rate at the beginning.
It decreases over time as the soil becomes saturated.
Basic infiltration rate is the rate after the soil profile becomes saturated.
It is a constant rate.
Hydraulic conductivity is the ability of soil to transmit water.
Thus, the infiltration rate after saturation is the basic infiltration rate.

Step 4: Final Answer:
The infiltration rate after saturation is the basic infiltration rate.
Hence, the correct option is (C).
