RIX values in WAsP Resource Grid

[GSwan]

Hi,
I am seeking clarification on RIX values output in WAsP's resource grid.

- The RIX values represent the % area of land per WAsP node which 'probably' contains slopes greater than the acceptable 0.3, yes?
- At what % RIX does the model become potentially unstable?
- Is the delta-RIX value relative to a given nodes surrounding nodes?

Thanks for your help,

Have you checked the help file?

If you search for RIX you'll find a section called "Limitations of the flow model".

An explanation of the delta-rix approach is given in http://www.wasp.dk/Support/DownloadFiles/Influence%20of%20topographical%20input%20data.pdf

Check out the literature in general on the WAsP web site: http://www.risoe.dtu.dk/en/WAsP/Support/Literature.aspx. There are several papers and reports on complex terrain, RIX and dRIX.
