Irrigation Water Conveyance and Application Methods

A border irrigation strip of width $W = 10\text{ m}$ and length $L = 100\text{ m}$ is irrigated with an inflow stream of $Q = 0.02\text{ m}^3/\text{s}$. If the average water infiltration rate into the soil is $f = 0.00001\text{ m/s}$ ($3.6\text{ cm/h}$), calculate the maximum border strip area $A_{\max} = Q / f$ in $\text{m}^2$ that this stream can theoretically cover before advance ceases.
