Tutorial #2 of 3 - Understanding Flow Accumulation in GIS from raster Data of elevation ?

This video is about understanding the concept behind flow accumulation. Flow accumulation means add all the flow entering into the particular cell. This is how GIS software like QGIS uses to determine flow accumulation.

PLEASE NOTE: The arrow should be directed towards cell with value 88 from cell with value 134 and the flow accumulation would change accordingly. But since this video is focused on flow accumulation, not flow direction, the flow accumulation is drawn according to current flow direction.

The flow directions on elevation 134, 98 and 88 are incorrect. They should be down right, down left, and downright.

so, flow accumulation value , are unitless?

[@vishvincent6947]

Can u plz tell how to determine flow accumulation threshold before stream ordering.?

[@ashmeeradahal4652]

What about 134 cell??????😥🤔🤔🤔
