Hi everybody, a question concerning watershed creation.<br>I've got an hydrological network and a map of points. I want to create watershed. Currently I use the r.water.outlet command to do this. But Know I want to create watershed only between two nodes of my network (it is not a real watershed on the common hydrological point of view; it's just only a part of this).
<br>I've got a solution but I don't know if it's the good way: create each watershed with one outlet point and after overlay each watershed with another watershed to erase the part which overlay. But I need to know in which way to overlay (need to find which outlet is upstream or downstream of another outlet). I need to know which watershed is upstream of an other watershed
<br>So I think I need to use a network (<a href="http://v.net">v.net</a> command) but how to find that a point is upstream or downstream of another point ?<br>Is it a way more simple to do it ? (using a command like r.water.outlet
but with limit in downstream and upstream to create a watershed only between two points; and not between one point and the beginning of the hydrological network)?<br>Thanks for your responses !!!<br><br><br>Mick
