I've been having the same problem. I have seen figures illustrating the issue in riparian areas, where the watersheds 'end', leaving holes where perhaps very small watersheds should be delineated along rivers/streams instead. Personally, I am having this issue along coastlines, but its the same as in the riparian case. I can't even fill the holes with a tiny threshold and I'm hesitant to make up my own watersheds at the coast.<div>

last year you asked me whether the r.watershed output is not aligned to the r.water.outlet output in GRASS7 (s.b.). Ie. it leaves small areas out. Back then, I wasnt using GRASS7, but I can confirm now that it still does it and it is still rather annoying. Have you ever heard of the reasons or attempted to fix this?<br>
Thanks,<br>
Michel<br>
