A rectangular chute spillway is designed for gully erosion control with a drop (H) of $5 \mathrm{~m}$, peak flow of $1.81 \mathrm{~m}^{3} \mathrm{~s}^{-1}$ and maximum inlet water level of $0.81 \mathrm{~m}$. Frictional head loss over the apron is $20 \%$ of $\mathrm{H}$. The design height of chute blocks is equal to the depth of flow in the water way. Acceleration due to gravity (g) is $9.81 \mathrm{~m} \mathrm{~s}^{-2} .$ If coefficient of discharge of the weir section is 1.66, height of the chute blocks is _____________$\quad \mathrm{m}$.
