Soil Infiltration Rate Formula
The following two example problems outline the steps and information needed to calculate the Soil Infiltration Rate.
SIR = WD / T
- Where SIR is the Soil Infiltration Rate (in/min)
- WD is the water depth (in)
- T is the elapsed time (min)
How to Calculate Soil Infiltration Rate?
The following example problems outline how to calculate Soil Infiltration Rate.
Example Problem #1:
- First, determine the water depth (in).
- The water depth (in) is given as: 5.
- Next, determine the elapsed time (min).
- The elapsed time (min) is provided as: 30.
- Finally, calculate the Soil Infiltration Rate using the equation above:
SIR = WD / T
The values provided above are inserted into the equation below and computed.
SIR = 5 / 30 = .167 (in/min)
Example Problem #2:
For this problem, the variables required are provided below:
water depth (in) = 6
elapsed time (min) = 10
Test your knowledge using the equation and check your answer with the calculator..
SIR = WD / T = ?
