A rough approximation to flow direction is just slope orientation/aspect.

Hi List,

Does anyone know how I can create a tab or grid map showing the major
direction of Water movement in a mountain using MapInfo/Vertical Mapper?
Lets say I have a topography tab or grid file, and am looking for the major direction of water movement. In other word, lets say if there is a rainfall, or melting snow in a mountain, what are the major path way of water in this
mountain? Itcould be couple of directions.

Thanks
Regards
Ali
