Question $2[10$ points$]$

For a precipitation event in a watershed of interest, Table $1$ shows the Unit Hydrograph

for the watershed on the left, and the excess rainfall at times $1,2,$ and $3$ on the right.

Using the convolution method, find the direct and total runoff from the watershed.

Assume the watershed has a constant baseflow of $8f\frac{t^3}{sec}.$
