Thanks for sharing. I do have a question on , why don't we consider the wetted volume instead of area?

Excellent video. Do you have boot class

Hi, thanks for this great video. maybe I'm missing something but in the wetted area calculation it seems that the equation is maybe missing something.
you are multiplying 100% by 2 distance units (depth and width) and dividing only by one distance unit (dripline distance) which means your wetted area result is in percentage X distance (in the example on 4:16 the result is 10%meter instead of 10%). seems to me you should be dividing by another distance unit.

The total depth of the soil is 1m for the TAW as stated in the FAO table. so 1.5m x1m is 1.5sqm. so the proportion of the wetted perimeter to the tota TAW is ((0.3x0.5)/ (1.5m x 1m)) x 100%
