In Step 7 a ModuleConfigFile is produced which uses a PCRaster transformation. This PCRaster transformation is used for the following 3 steps:

1. PCRaster determines the discharge of the tributaries; the flow of the branch rivers is substracted from the total surface water flow.
   only_Q_tributaries = Qflow * branches_grid;
2. Sums the discharges of all upstream river cells
   sum_Q_tributaries = upstream(stream_directions, only_Q_tributaries);
3. Make the map with discharges of all upstream river cells at the crossing points of rivers.
   Output = sum_Q_tributaries * cross_points;

This PCRaster tranformation needs input to be able to run and therefore To make the PCRaster calculation in NGMS the following xml files have to be created:
