List of top Civil Structural and Transport Engineering Questions on Open Channel Flow

Critical depth in a channel is expressed by: (where $Q =$ discharge, $A =$ Area of flow, $T =$ top width of flow and $g =$ acceleration due to gravity)

Match LIST-I with LIST-II:\[\begin{array}{|c|l|l|} \hline \textbf{LIST-I (Flow parameter of a channel flow)} & & \textbf{LIST-II (Proportional to)} \\ \hline \text{A. Mean velocity in a Lacey regime channel} & & \text{IV. $Q^{2/3}$} \\ \hline \text{B. Mean velocity in a lined channel} & & \text{II. $S^{1/3}$} \\ \hline \text{C. Normal scour depth in an alluvial channel} & & \text{III. $Q^{1/2}$} \\ \hline \text{D. Wetted perimeter of a Lacey regime channel} & & \text{I. $S^{1/2}$} \\ \hline \end{array}\] where $S$ is slope of channel and $Q$ is discharge. Choose the most appropriate match from the options given below:
