A vertical column filled with soil is undergoing steady state saturated flow. The column is $50$

cm high and has a cross sectional area of $15$ cm$2$

$.$ The datum elevation is chosen at the base

of the column. The pressure heads at the top and bottom of the column are $0$ and $55$ cm$,$

respectively. The hydraulic conductivity of the medium is $4$x$105$

cm s$1$ and the porosity

is $0\mathrm{.}3$ m$3$ m$3$

$.$ Calculate the volumetric flow $($Q$),$ the Darcy flux $($q$)$ and the average linear

groundwater velocity $($v$).$ Is the flow towards the top of the column or towards the base?

Imagine if we tilted the column to a $45$ angle without adjusting the pressure heads... would

the flow rate increase or decrease
