During a $10$ hour rainfall, precipitations in Table are observed.

Table: Precipitations $($mm$)$

a$)$ Considering that initial infiltration capacity is $30m\frac{m}{h}$our, limit value of

infiltration capacity is $5m\frac{m}{?}$ hour, Horton parameter $--$k$--$ is $0\mathrm{.}3,$ calculate total

infiltration and direct runoff.

b$)$ Assuming that depression and interception losses are ignorable,calcule $$

and $w$ indices.
