QUESTION $3[15]$:

The data given in the table below was recorded for a catchment area of $11k{m}^2$ for a storm of intensity $100m\frac{m}{h}$ lasting for $15$ minutes.

$\backslash$table$[[$Time$($hrs$),0,1,2,3,4,5,6,7,8,9],[$Flow $(\frac{m^3}{s}),3,3,9,13,17,13,8,6,4\mathrm{.}4,4\mathrm{.}3]]$

a$)$ Draw a hydrograph for this storm.

$(2)$

b$)$ If the baseflow increases by $0\mathrm{.}2\frac{m^3}{s}$ every hour, draw the baseflow separation line on your hydrograph
