The image shows the three rivers in an area just west of the town of Nijmegen, the Netherlands: the Lower Rhine (top), the Waal (centre) and the Maas (bottom). The swollen rivers are clearly delineated in dark magenta, while the normal river courses can be identified by the black parallel lines within the flooded area showing the position of the raised river banks.
The top left area is covered only by two acquisitions, and consequently appears in yellow.
