Answer:
There are 2 types of infiltration indices – Phi index and W index. ... W-index – It is the average infiltration rate that is calculated during the time when the intensity of rainfall is exceeding the infiltration rate. The W-index is much more accurate than the phi-index because it subtracts the initial losses also.
