A rectangular chanel $3$m wide discharges $13\mathrm{.}5$m$^3/$s construct a specific energy curve and state the types of flow when;

I$)$ Depth of flow is $0\mathrm{.}6$m

ii$)$ Depth of flow is $2\mathrm{.}4$m

iii$)$ Determine their corresponding specific energies and the bed slope required to maontain those depth of flow.Take manning n$=0\mathrm{.}014$
