Frequently Asked Questions (FAQ)

• What is the formula of hydraulic depth?

• To calculate the hydraulic depth use the formula Hd = A/W, where A is the area of the cross-section and W is the width of the channel.

• What is hydraulic depth?

• The hydraulic depth is the ratio of the cross-section area of a flow through a pipe to the wetted perimeter of the conduit.

• What is normal hydraulic depth?

• Normal depth is the depth at which uniform flow will occur in an open channel or culvert. It is a constant depth of flow at all points along the channel. Normal depth occurs when the gravitational force of the water is equal to the friction drag along the culvert and there is a constant flow rate.
