The cumulative frequency graph below shows the inflow and outflow TSS concentrations for a pond treatment node downstream from another storage. There are substantial periods of zero flows. When flow is zero, the concentration is undefined, leading to truncated curves of the form shown. The use of Flow-Based Cumulative Frequency Graphs in such cases as this is described here.
Note: To view or save these model outputs after the run, you need to record Flow Based Cumulative Frequency Graph before you run.
