"Mouths into" indeed sounds awkward (and I'm not using it), but I think Henk was getting at the fact that this word is influenced from the French word "bouche". I had already used "flows through" for "stroomt door" as it appears quite frequently in the text. I had also ruled that out already considering lots of other things flow into rivers (e.g. sewage, lava etc.). That's not to say it's an unsuitable translation, however. "discharge" carries the connotation of being forced into the Tarn or emerging _from_ something rather than into. "tributary to", "empties into" & "debouches into" are the most suitable translations since they all indicate smaller bodies of water flowing into a larger body. Nonetheless, "debouche" also carries the connotation of going from smaller or more confined area into the open country. Location names also are appropriate in the place of "de Tarn", and that is the case for some other areas in the translation where "uitmonden" is used. So this is suitable, for the sake of consistency. Plus the text as a whole is about France, so it adds a little cultural flavor to leave it simply "debouch" while being entirely correct in all contexts. Thanks again for the input"
