The daily streamflow data at a site having a drainage area of $650k{m}^2$ are given below.

Compute $($show all graphical work when applied$)$:

$($a$)$ Total streamflow volume over the measurement period

$($b$)$ Baseflow volume $($separate the baseflow using recession curve method$)$

$($c$)$ Compare baseflow fractions using at least $3$ different separation methods
