WRAT-Documentation and segmentation fault

[Andreas Paukner-Ruzicka]

Hello  GRASS-Users 
Is there any documentation about WRAT ? . I want to use this model  in my project  estimating pollutant immisions into a lake in southern bavaria.

Another problem concerning r.wrat: If I start it it terminates with a segmentation fault. 
What to do ?

Many thanks in advance !
