The volume of water that can be extracted by the force of gravity from a unit volume of an aquifer material is called specific yield.
(Specific.retention=The ratio of the volume of water that given a body of rock that hold against the pull of gravity.
Specific storage= quantity that which water well can produce)

Specific Yield of an Aquifer Material

Specific yield is the volume of water that can be extracted by the force of gravity from a unit volume of an aquifer material. It is expressed as a percentage or fraction of the total volume of the aquifer. Specific yield is an important parameter in hydrogeology, as it determines the amount of water that can be pumped from a well.

Calculation of Specific Yield

Specific yield is calculated by dividing the volume of water that can be extracted from an aquifer by the total volume of the aquifer material. It is expressed as a percentage or fraction of the total volume of the aquifer.

Formula: Specific Yield = (Volume of water extracted from the aquifer) / (Total volume of the aquifer material)

Importance of Specific Yield

Specific yield is an important parameter in groundwater management and well design. It determines the amount of water that can be extracted from a well and the rate at which the water can be pumped. Specific yield also helps in estimating the amount of water that can be stored in an aquifer and the time it takes to recharge the aquifer after pumping.

Conclusion

Specific yield is the volume of water that can be extracted by the force of gravity from a unit volume of an aquifer material. It is an important parameter in hydrogeology as it determines the amount of water that can be pumped from a well. Specific yield is calculated by dividing the volume of water that can be extracted from an aquifer by the total volume of the aquifer material. It is expressed as a percentage or fraction of the total volume of the aquifer.
