The image above represents total storage. To calculate total storage, three essential parameters are needed, and these parameters are Storage co-efficient (k), Dimensionless constant (x) and Average outflow rate (O).
The formula for calculating total storage:
s = k[x + (1 – x)O]
Where:
s = Total Storage
k = Storage Co-efficient
x = Dimensionless Constant
O = Average Outflow Rate
Let’s solve an example;
Find the total storage when the storage co-efficient is 12, the dimensionless constant is 10 and the average outflow rate is 6.
This implies that;
k = Storage Co-efficient = 12
x = Dimensionless Constant = 10
O = Average Outflow Rate = 6
s = k[x + (1 – x)O]
Then, s = 12[10 + (1 – 10)6]
s = 12[10 + (-9)6]
s = 12[10 + -54]
That means: s = 12[-44]
s = -528
Therefore, the total storage is -528.
Calculating the Storage Co-efficient when the Total Storage, the Dimensionless Constant and the Average Outflow Rate are Given
k = s / [x + (1 – x)O]
Where;
k = Storage Co-efficient
s = Total Storage
x = Dimensionless Constant
O = Average Outflow Rate
Let’s solve an example;
Find the storage co-efficient when the total storage is 32, the dimensionless constant is 8 and the average outflow rate is 4.

This implies that;
s = Total Storage = 32
x = Dimensionless Constant = 8
O = Average Outflow Rate = 4
k = s / [x + (1 – x)O]
So, k = 32 / [8 + (1 – 8)4]
k = 32 / [8 + (-7)4]
k = 32 / [8 + -28]
That is, k = 32 / [-20]
k = -1.6
Therefore, the storage co-efficient is -1.6.
