A $1 \mathrm{~m}$ wide rectangular channel carries a discharge of $2 \mathrm{~m}^{3} / \mathrm{s}$. The specific energy-depth diagram is prepared for the channel. It is observed in this diagram that corresponding to a particular specific energy, the subcritical depth is twice the supercritical depth. The subcritical depth (in meters, up to two decimal places) is equal to
