Ok

I have just found the following formula:

R=0.366*res/h * log ( 3* h/d)

where
res=Resitividad  [ohm-meters]
h=depth of ground road[m]
d= diameter of ground road [m]

Is this correct?
So in my case with a ground road of 5/8'' of 2.5m and the resistivity of 
500 ohm-meters
I should get 50 ohm ...
And with 2 ground roads I should get 25 ohm?
This seems the point I have missed ...

Is this right?

Beat
