Soil Recharge - meaning and units?

Soil Recharge - meaning and units?

Soil Recharge - meaning and units?

(OP)
I’m starting  a corrosion study (my specialty) and need to consider the soil and “recharge" of the soil (NOT my specialty)

I’ve have data sources that discuss the moisture of soil (and other parameters) in terms of percent and resistivity (and conductivity, of course), and these terms/descriptions make perfect sense to me.

I also have a data source that describes “recharge of 0.1 and 0.5 millimeters per year recharge (and other values).  I know the term “recharge” is simply the amount of water added or absorbed, but I do not understand the units?  

Any helpers out there?  Thanks

RE: Soil Recharge - meaning and units?

I read it to mean simply that 0.1 to 0.5 mm of precipitation (rainfall and snow melt) are expected to percolate/infiltrate into the soil.

Remember: The Chinese ideogram for “crisis” is comprised of the characters for “danger” and “opportunity.”

RE: Soil Recharge - meaning and units?

this is an extremely low value for percolation and usually percolation is a rate of infiltration per minute, per hour, per day, but not per year.    I think you need to do some further research into the data you have obtained to verify the units or the infiltration rates.
