Chapter 2: Uniform Flow

In uniform flow, which parameters remains constant?

• Flow depth

• Energy

• Cross-sectional area

• Channel bed slope

What is the general flow equation?

• Q = Av

• Q = 1/n * A * R^(2/3) * S^(1/2)

• Q = A * C * R * S

Define the conveyance factor.

• Capacity of the channel to carry the flow

• Characteristics of channel geometry

• Flow rate per unit width

From the list below, choose one method to calculate normal depth.

• Best Hydraulic Section (BHS) method

• Manning’s method

• Graphical method

• Shield’s method

Why is the best hydraulic section (BHS) is called the most efficient cross section?

• Economically designed

• Reduce construction material price on the market

• Convey maximum designed discharge

• Designed with minimum flow depth
