Problem $2$: Given the rainfall mass curve and the total hydrograph of a storm below that has taken place in basin$($ area $=16km2),$ determine

a$)$ hyetograph of the storm and plot as a bar chart

b$)$ direct runoff hydrograph and plot $($m$3/$s$)($use constant baseflow model for baseflow separation$)$

c$)$ depth of surface runoff

d$)$ unit hydrograph for this storm and plot.
