 \section{Input}
 \todo{Data Description Input}
 
+\subsection{Sigma Tau Curves}
+As part of the soil parameters, sigma tau curves can be used to determine the shear strength in stability calculations.
+A full description of the used method can be found in \citep{MacroStabilityReqAndFD22}.
+
+In order to use sigma tau curves in DAM, the name(s) of the curve(S) to be used must be added to the \textit{soils.csv} at column \textit{sigma\_tau\_curve\_name} and the proper shear strength model (\textit{SigmaTauCurve}) must be selected for that soil.
+Next to that, the sigma tau curves must be defined in their own csv-file (\textit{sigma\_tau\_curves.csv}). Both csv files use the \textit{sigma\_tau\_curve\_name} to couple the data.
+
+For more information, see the \citep{DAMUI_Manual}.

 \section{Results}
 First of all,
 not all calculations will pass kernel validations or lead to valid results due to errors that occur in the calculations (e.g. uplift does not occur where it is expected).
