corbelling is when you move inward a bit on every bag(using the 
earth bags this example) thus the circle gets tighter as you lay 
bags. The shape of the dome is not round but sort of a lancet type 
arch. They will be  higher than a round dome,  that is the height 
can be the same as the diameter of the dome. 

The down pours are not what you have to worry about, it's the long 
slow drizzles that last days and days, thats what you have to worry 
about.
