It appears that amounts of sediment are carried along when water is overflowing over the banks of the river: part of the sediment from sediment fractions SF1 and SF2 leaves the river and goes to the Storage Areas during flooding. Although this is taken into account in the sediment balance, there is no variable being saved for the Storage Node in order to know how much sediment may accumulate in that storage area, nor can it be exported or visualized. Could you add the quality variable "sediment depth" present for the river sections also for the storage node (you don't really expect any bed offset in a Storage Area) ?
