Hello everyone! Does the 'watershed' function of manifold 9 use the same base information as the 'FlowStreams(dir, acc, thr)' function of manifold 8? When it calculates streams and watersheds, does it take into account flow direction and flow accumulation as it does in the manifold 8 function? I searched the manual, but I only noticed a reference to this in the 'Manifold vs Arc - Watersheds Sixty Five times Faster than Arc video'.

9 functions are different than 8 functions and have different arguments. For what 9 watershed functions do see the SQL reference for Tile functions and look up TileWatershed... functions. For explanations of fields used see the Watersheds topic, for example...

mfd_id

Manifold identify field.

Geom

The geometry of the area or stream watershed object.

Stream

A unique, numeric, watershed identifier for the watershed area or stream line object.

Target

The watershed identifier for the watershed area or stream line object into which water from this object flows.

OrderShreve

Watershed order computed using Shreve ordering.

OrderStrahler

Watershed order computed using Strahler ordering.

Value

The flow contributed by this watershed object.

ValueSum

The total flow through this watershed object, including all flow from upstream watershed objects as well as flow from this object.
