+\subsubsection{Mapping of pl lines to waternet}
+\label{sec:MappingPlLinesToWaternet}
+
+Dam Engine has a set of pl lines: Pl 1, Pl 2, Pl 3, Pl 4. Pl 1 is the phreatic line and it always exists. The other pl lines are optional. The pl lines from the Dam Engine are converted to a waternet that can be used in WBI Macrostability.
+
+The waternet consists of a phreatic line, a list of head lines and a list of waternet lines. Each waternet line can have an associated head line.
+To create the waternet lines the soil profile data is used to determine the 'bottom aquifer' (the lowest set of one or more connected aquifer layers) and the 'in-between aquifer' (the first aquifer (layer set) that lies above the bottom aquifer).
+
+Pl 1 becomes the phreatic line. \\
+If Pl 2 exists it becomes a head line. If there is at least one aquifer, a waternet line is created along the top of the bottom aquifer + penetration length. \\
+If Pl 3 exists it becomes a head line. If there are at least two aquifers, a waternet line is created along the top of the in-between aquifer. \\
+If Pl 4 exists it becomes a head line. If there is at least one aquifer, a waternet line is created along the top of the bottom aquifer. \\

 \subsection{Mapping of the validation result}
 \label{sec:MappingValidationResultWbiMacrostability}
 The \WbiKernel returns the validation result when the Validate function is called. In the following table a mapping of the validation result to the \ProgramName data is defined.
