What is the purpose to know the soil water index? The factors that impact on moisture in soil are temperature, humidity, permeability, rate of percolation & green cover & evapo-transpiration. It is good indicator to manage the irrigation for the crop.

The Soil Water Index provides estimations on average amounts of water
stored in soil of certain areas, helping to clarify the risk of landslide-related
incidents caused by heavy rain. JMA uses index values as criteria for the
issuance of Emergency Warnings, Warnings Advisories for heavy rain and
Landslide Alert Information. Is not a good indicator of water availability for crops.
