... between the BET and the EFA indicates that the BET gives a soil erosion resistance higher than the EFA does; this may be attributed to sample disturbance for the EFA and testing under favorable in situ stresses for the BET. Two parallel BETs, one with water and one with drilling mud, shows 10 % more...
