\chapter{REQCalcAssessRegional} \label{sec:RRDScenarioSelection}

For the assessment of regional dikes, \ProgramName must calculate several assessment scenarios (RRD-scenario) depending on:

 \begin{itemize}
	\item the type embankment (peat/other); green block in \autoref{fig:RRDClay} and \autoref{fig:RRDPeat};
	\item the hydraulic shortcut (yes/no); brown block in \autoref{fig:RRDClay}, \autoref{fig:RRDPeat} and in detail in \autoref{fig:HydraulicShortcut};
  \item the uplift situation (yes/no); purple blocks in \autoref{fig:RRDClay} and blue blocks in \autoref{fig:RRDPeat}.
\end{itemize}

This results in a variation of RRD scenarios, summed up in \autoref{tab:RRDScenarios}
