Question $2$

Figures Q$2$a and Q$2$b show the rainfall hyetographs that two hydrologists have provided you for a storm event that

produced a runoff volume of $70000$m$^(3)$ from a $10$km$^(2)$ catchment. Using the Phi$-$Index method, determine the infiltration

capacity $(\backslash$phi $)$ of the catchment using each of the hyetographs.Figure $2$a
