 \subsection{Example Drain Discharge Scaling Calculations}
 
-An example of the differences between the standard, linearly-scaled, and cubicly-scaled drainage discharge are shown in figure~\ref{fig:drndischdiff}. In this example the elevation that drainage discharge starts ($\mli{ZDRN}$) is set at $\frac{\mli{DDRN}}{2}$ below land surface elevation and drainage discharge is equal for all approaches at $\mli{ZDRN} + \mli{DDRN}$ (fig.~\ref{fig:drndischdiff}\textit{A}). In this conceptual problem, the groundwater head linearly increases from a value less than $\mli{ZDRN}$ to greater than $\mli{ZDRN + DDN}$ during the simulation, which is presented as the head difference ($h - \mli{ZDRN}$) divided by the drainage depth in figure~\ref{fig:drndischdiff}\textit{B}. The drainage discharge that results from the linear increase in groundwater head using the original-, linear-, and cubic-scaling increases with time as is shown in figure~\ref{fig:drndischdiff}\textit{C} and shows the continuous nature of the linear- and cubic scaled drainage discharge and that all three approaches result in the same drain discharge rate when the relative drain head difference is greater than or equal to one. Figure~\ref{fig:drndischdiff}\textit{D} shows that the cumulative drain discharge for the original drain formulation is 170 to 200 $L^3$ greater than the cubic- and linear-scaled drainage discharge, respectively.
