QUESTION $1[15]$:

The aquifer shown in the figure below has a width of $2\mathrm{.}5$ km $.$ During excavations for road aggregate, a $22$ m section along the width of the aquifer is cut. The hydraulic conductivity of the aquifer is $0\mathrm{.}0002\frac{m}{s}.$

a$)$ What type of aquifer is depicted in the figure?

$(2)$

b$)$ Use Darcy's law to calculate the quantity of water collected over $5$ days in the excavated portion.

$(6)$

c$)$ Determine the pressure head and total head for the well if the elevation head is $204$ m and the depth of the well is $87$ m $.$

$(4)$
