Interception and LAI for central europa

[Steeve EBENER]

Hello,

I am doing a pHD regarding water flow systems in a watershed. In order to 
estimate the potential of the intercepted part of preciptation I found this 
relation:

		I = 0.2 * LAI (Dickinson, 1984)

So, I need to know the Leaf Area Index for the different kind of vegetation we 
can find in central europa. 

As I am regarding the variation of the diferent elements of the hydrological 
cycle over one year (using a monthly basis) I need to have an idea of the 
variation of the LAI too.

Any comment on this relation or help for finding the LAI would be greatly 
appreciated.

Sincerely yours,
