Is it possible to get array of streams in the sequence they get filled? #39

Streams are normally filled in order depending upon their relative hight. Many hydrological modeling number streams while creating subbasin files like BASINS etc. How can such an array be obtained in this case?!!!

Hi Ather,

Do you mean stream order (https://en.wikipedia.org/wiki/Stream_order)?

It's been on my to-do list for a while, but I haven't gotten to it yet. Maybe I can implement it within the next few weeks.

AtrCheema commented 6 years ago

Thank you for your response. Yes, I mean similar to stream order. The order calculated by e.g. BASINS is from 1 to max. no. of streams while the Wikipedia shows a bit different.

mdbartos commented 6 years ago

Do you have any links showing how BASINS assigns order to the streams? I haven't been able to find any info.

AtrCheema commented 6 years ago

Quite a while ago I tried to find it from BASINS src on Github. I couldn't. I will post it here if I find one.

Strahler stream order has been implemented in pysheds v0.3.
