Hydraulic depth can be defined as the cross-sectional area of flow divided by the top width of surface. It is a crucial parameter in calculations dealing with fluid mechanics and flow in open channels. Calculating the hydraulic depth of flow in open channels can be tricky and a powerful calculator can expedite the process.
But before we get into that, the formula for computing hydraulic depth is:
R = A / T
Where:
R = Hydraulic Depth
A = Cross-sectional Area of Flow
T =Â Top Width or Top Surface Water Width
For Example:
Find the hydraulic depth of flow in an open channel where the cross-sectional area is 120 m2 and the top width is 12 m.
From the example we can see that the cross-sectional area is 120 m2 and the top width is 12 m.
R = 120 / 12
R = 10
Therefore, the hydraulic depth is 10 m.
