Change in Storage in Muskingum Method of Routing Solution

Follow our step by step solution on how to calculate Change in Storage in Muskingum Method of Routing?

FIRST Step Consider the formula
ΔSv=K⋅(x⋅(I2-I1)+(1-x)⋅(Q2-Q1))
Next Step Substitute values of Variables
∴ ΔSv=4⋅(1.8⋅(65m³/s-55m³/s)+(1-1.8)⋅(64m³/s-48m³/s))
Next Step Prepare to Evaluate
∴ ΔSv=4⋅(1.8⋅(65-55)+(1-1.8)⋅(64-48))
LAST Step Evaluate
∴ΔSv=20.8
