Normal Depth in Hydraulics and Waterworks Formulas

Normal Depth is a depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant. And is denoted by y. Normal Depth is usually measured using the Meter for Length. Note that the value of Normal Depth is always positive.

FAQ

What is the Normal Depth?

Normal Depth is a depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant. Normal Depth is usually measured using the Meter for Length. Note that the value of Normal Depth is always positive.

Can the Normal Depth be negative?

No, the Normal Depth, measured in Length cannot be negative.

What unit is used to measure Normal Depth?

Normal Depth is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Normal Depth can be measured.
