Introduced estimation of meanTransit time for drainage water from different horizons and  an average Transit time for the total drainage from the profile. The estimation is turn on by using the Switch TransitTime. The estimated transit time for a certain layers is in the auxiliary array MeanTransitTime and the flow weighted arerage transit time is TotMeanTransitTime.
