+\chapter{Use of WBI piping kernel}
+\label{sec:UseDAMPipingKernel}
+
+Functional designs
+The functional design of the WBI piping kernel is described in \citep{WBIFOPipingKernel}
+
+The WBI use of the piping kernel consists of three sub failure mechanisms: uplift, heave and backward erosion. 
+The complete calculation is done by:
+\begin{enumerate}
+	\item The calculation of the uplift safety by determining the vertical balance of weight of the subsoil and the waterpressure at the top of the aquifer.
+\item The calculation of heave by checking the maximal gradient over the vertical waterflow at the uplift location. Heave is the vertical sand transport through the horizontal pipes towards the location of uplift breaching (the exit location.)The thickness layer is the distance where over heave occurs.
+\item Checking the presence of sufficient horizontal seepage length (kwelweglengte) 
+\item Determiniation of the piping safety factor by dividing the required seepage length by the present seepage length.
+\end{enumerate}
