Reading from the Book

Question 1

transmissivity

Answer 1

A measure of the amount of water that can be transmitted horizontally through a unit width by the full saturated thickness of the aquifer under a hydraulic gradient of 1.
T equals bK
where T is transmissivity b is saturated thickness of the aquifer K is the hydraulic conductivity.

Question 2

storativity

Answer 2

storage coefficient. The volume of water that a permeable unit will absorb or expel from storage per unit surface are per unit change in head. A dimensionless quantity.

Question 3

Specific storage

Answer 3

the amount of water per unit volume of a saturated formation that is stored or expelled from storage owing to compressibility of the mineral skeleton and the pore water per unit change in head.
