b$)$ The population for a town is $4000(1+\frac{F}{100}).$ The pattern of monthly flow measured over the three consecutive driest years for a stream is given in the table below. First generate the flow records for the stream for your exercise by multiplying the given values by a factor of $(1+\frac{F}{100}).$ Then:

$(10$ marks$)$

I. Using the Ripple $($Graphical$)$ method, explain if this water resource is sufficient to supply the township if the capita demand is $350\frac{L}{h}\frac{?}{d}.$

II$.$ Determine the minimum storage volume required to maintain a steady supply.

III. Determine the number of years the stream can supply drinking water if the population increases at a rate of $0\mathrm{.}5\%$ annually.
