The explosives will be detonated on the crest of the dam and on the slopes to establish the size of craters in relation to those on flat ground surfaces and to determine the effect of micro-cracking and micro-fissures on the permeability of the dam structure.

Reduction in effective stress on the other hand will lead to reduced shear strength of the embankment dam.
