Hi,
  
     I know to change landuse by modify  "Terrain/LANDUSE",   My question is "does the  height of mountains or elevation of some  earas  can affect the result of this model ?" If it is,  where and how to  change the mountain's height ? For example  , to reduce the height or increase or let a mountain disappear in input data when run RegCM3 ?
 
  If someone has done such experiments, please give me some suggentions.
 
    Thank you.
