Question $2$

Given the following $2-$hr unit hydrograph, calculate the $1-$hr unit hydrograph. Then back calculate and find the $2-$hr unit hydrograph to prove that the method of calculation is accurate.

Graph both unit hydrographs against time on the same plot.

$\backslash$table$[[$Time $($hr$),$Flow $($cfs$)],[0,0],[1,25],[2,125],[3,250],[4,400],[5,500],[6,450],[7,350],[8,300],[9,225],[10,150],[11,110],[12,30],[13,0]]$
