This time I show you just one river, the river Waal (see also here).
I grew up in the city of Nijmegen, and this nice, Roman founded city is located at this river Waal.
Since 20 years I live close to my birth place Amsterdam, which is 120 kilometers north-west of Nijmegen. But every time I'm visiting my old town and when I see this river Waal, its typical 'uiterwaarden' and the bridges, I feel like 'home'. Even though the city has changed, and most of my friends have moved to other places, too.

This is a so-called personalized stamp, which has been issued, via PostNL, by Quinta Buma, photographer from Nijmegen.
She also designed this postcard, on which you see a little more of this river:

The Waal is said to have been founded because of a quarrel between two giants, two brothers.
Long time ago these brothers started to dig a river in Switzerland, the river Rhine. After hundred years of digging they arrived at Lobith, where they got a fight. Each of the brothers went his own way. The younger giant continued digging out what's named the Rhine nowadays, the older brother created the river Waal.
PostNL (then TPG Post) has issued a stamp sheet in honour of Nijmegen in 2005, on which you can see parts of the river Waal, too:
