This exercise is the last series of basic analysis of hydrological data. We will use a precipitation dataset from the previous exercise here and additional flow data at Saugeen here.
At this time, we will explore seasonal analysis and visualization, including creating a hydrograph and a hydrograph with baseflow and additional plot and flow duration curve. This exercise will involve the
