Display Flow Directions on ground surface by ArcGIS


Hi Water Networks Fellows,

I am a GIS Engineer. I would like to gently ask about flow directions by ArcGIS or QGIS.

I've a size of dem 0.1m by 0.1m.

I would like to draw raster file as below. 



questions :

  1. How to do it to generate the DEM like above?

  2. All of path are arrow shapes, is it possible to generate like it?
