Question

Specific yield and water holding capacity of soil

Answer 1

Explanation:

Specific yield is defined as the ratio of the volume of water that a srturated rock or soil will yield by gravity to the total volume of the rock or soil. Specific yield is usually expressed as a percentage.

The value is not definitive, because the quantity of water that will drain by gravity depends on variables such as duration of drainage, temperature, mineral composition of the water, and various physical characteristics of the rock or soil under consideration.

Values of specific yield, nevertheless, offer a convenient means by which hydrologists can estimate the

water-yielding capacities of earth materials and, as such, are very useful in hydrologic studies.
