Rule
of Thumb for Deposition Beginning
on Concave Slopes
Average
steepness of concave
portion
Deposition begins
Deposition
begins at location where
steepness = ½ average steepness
of concave portion
Example:
Assume average
slope of concave
section = 10%
½ of 10% is 5%
Deposition begins
at location where
the steepness is 5%
