For the flow setup shown in the figure (not to scale), the hydraulic conductivities of the two soil samples, Soil $1$ and Soil $2,$ are $10 \mathrm{~mm} / \mathrm{s}$ and $1 \mathrm{~mm} / \mathrm{s}$, respectively. Assume the unit weight of water as $10 ~ \mathrm{kN} / \mathrm{m}^3$ and ignore the velocity head. At steady state, what is the total head (in $\mathrm{m}$, rounded off to two decimal places) at any point located at the junction of the two samples? _____________
