Volume of Water Drained by Gravity given Specific Yield

Go Volume of Water Drained by Gravity = (Specific Yield Percentage*Total Volume)/100

Specific Yield given Total Volume

Go Specific Yield Percentage = (Volume of Water Drained by Gravity/Total Volume)*100

Total Volume given Specific Yield

Go Total Volume = (Volume of Water Drained by Gravity/Specific Yield Percentage)*100

Specific Retention given Total Volume

Go Specific Retention Percentage = (Volume of Water Retained/Total Volume)*100

Specific Retention given Porosity Formula

Specific Retention Percentage = Volume Percent of Porosity-Specific Yield Percentage
%S_r = η_v-%S_y

What is Specific Retention?

The ratio of the volume of water that a given body of rock or soil will hold against the pull of gravity to the volume of the body itself. It is usually expressed as a percentage.
