 lowest box the river water is being added to (i.e. the total depth that river water is being added to in the model).
 
+%Christian:
+If the depth information is not provide in the NetCDF file, it can be estimate from the runoff input file at the initial time-step, by setting the namelist parameter \np{ln\_rnf\_depth\_ini} to true.
+
+This estimation is a simple linear relation between the runoff and a given depth : 
+\begin{equation} 
+h\_dep  = \frac{rn\_dep\_max} {rn\_rnf\_max}  rnf
+\end{equation}
+where  \np{rn\_dep\_max} is the given maximum depth over which the runoffs is spread, 
+ \np{rn\_rnf\_max} is the maximum value of the runoff climatologie over the global domain
+and rnf is the maximum value in time of the runoff climatology at each grid cell (computed online).
+
+The estimated depth array can be output if needed in a NetCDF file by setting the namelist parameter \np{nn\_rnf\_depth\_file} to 1.
+
 The mass/volume addition due to the river runoff is, at each relevant depth level, added to the horizontal divergence 
 (\textit{hdivn}) in the subroutine \rou{sbc\_rnf\_div} (called from \mdl{divcur}).
