Hydraulic Engineering - Open Channel Flow

Lacey's regime equations, followed in India for making scour calculations while designing hydraulic structures across alluvial channels, are given below. Regarding these equations, which of the following statements is/ar...

A round-bottom triangular lined canal is to be laid at a slope of 1 in 1500, to carry a discharge of 25 m³/s. The side slopes of the canal cross-section are to be kept at 1.25H : 1V. If Manning's roughness coefficient is...
