How to Calculate and Solve for Storativity of a Confined Aquifer | Aquifer Characteristics

Last Updated on April 6, 2024

The image above represents storativity of a confined aquifer. To calculate the storativity of a confined aquifer, two essential parameters are needed and these parameters are Saturated Thickness of Aquifer (b) and Specific Storage (Ss).

The formula for calculating storativity of a confined aquifer:

S = bSs

Where:

S = Storativity of a Confined Aquifer
b = Saturated Thickness of Aquifer
Ss = Specific Storage

Let’s solve an example;
Find the storativity of a confined aquifer when the saturated thickness of aquifer is 10 and the specific storage is 2.

This implies that;

b = Saturated Thickness of Aquifer = 10
Ss = Specific Storage = 2

That is, S = bSs
S = (10)(2)
S = 20

Therefore, the storativity of a confined aquifer is 20.

Calculating the Saturated Thickness of Aquifer when the Storativity of a Confined Aquifer and the Specific Storage are Given

b = S / Ss

Where;

b = Saturated Thickness of Aquifer
S = Storativity of a Confined Aquifer
Ss = Specific Storage

Let’s solve an example;
Given that the storativity of a confined aquifer is 20 and the specific storage is 5. Find the saturated thickness of aquifer?

This implies that;

S = Storativity of a Confined Aquifer = 20
Ss = Specific Storage = 5

This means, b = S / Ss
b = 20 / 5
b = 4

Therefore, the saturated thickness of aquifer is 4.

Calculating the Specific Storage when the Storativity of a Confined Aquifer and the Saturated Thickness of Aquifer are Given

Ss  = S / b

Where;

Ss = Specific Storage
b = Saturated Thickness of Aquifer
S = Storativity of a Confined Aquifer

Let’s solve an example;
Find the Specific storage when the saturated thickness of aquifer is 50 and the storativity of a confined aquifer is 250.

This implies that;

b = Saturated Thickness of Aquifer = 50
S = Storativity of a Confined Aquifer = 250

This means, Ss  = S / b
Ss  = 250 / 50
Ss  = 5

Therefore, the specific storage is 5.
