The image above represents total storage.

To compute for total storage, three essential parameters are needed and these paramters 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]

s = 12[10 + (1 – 10)6]

s = 12[10 + (-9)6]

s = 12[10 + -54]

s = 12[-44]

s = -528

Therefore, the **total storage **is **-528.**
