The correct option is B 3 2 4 1
If the flow properties say the depth of flow, in a channel, remains constant along the length of the channel it is called uniform flow. Flow in the main irrigation channel is a uniform flow.
If the change of depth in a varied flow is rapid and appreciable it is called a rapidly varied flow. In a stilling basin, the hydraulic jump is confined either partly or entirely for energy dissipation. Hydraulic jump is associated with a rapid and significant change in-depth and other flow properties.
An unsteady flow occurs when the flow properties, such as the depth of discharge at a section changes with time. The sudden closure of a sluice gate creates such phenomena upstream of the gate.
If some flow is added to or abstracted from the varied flow it is known as a spatially varied flow. When irrigation water spreads over a field some water percolates down into the soil creating a spatially varied flow.
