Watershed_outputs - Empty Attribute table

edited April 2014 in Terrestrial Models
Hi,

I am using version 3.0.0 of the sedimentation module.
The model seems to work, I get a completed successfully message, outputs are created, but, the watershed_output table is mostly -1. Except for two, and these are not the smallest so it can't be watershed size.

I do get a few warnings towards the end and the log file is cut short.
Any ideas?

Failing a solution - how can I calculate the same attributes from the raster outputs. I am presuming this is a summation?

many thanks
Benjamin

  • Ok. I think I have found out why the watershed shapefile is not being produced correctly.

    I was conduting a trial on one watershed (one of many). The DEM was an extraction (clip) of a larger DEM, which I then filled and cleaned stream flow. There must have been irregularities in stream fow definition. When I repeat using a clip from a pre-filled DEM it works....make sense ?

    Sorry to take so long to respond, but that makes sense. A bad dem won't route and the -1 is probably the default nodata value that got aggregated under your watersheds.
