reducing mass movement

Question 1

grading

Answer 1

geometry of slope is altered by moving material from top to bottom. makes it less steep and therefore reduces sheer strain

Question 2

hydrogeological

Answer 2

groundwater is lowered or slope water content reduced. drainage trenches may be cut into slope which can be made deeper depending on steepness of slope

Question 3

mechanical

Answer 3

attempts to increase sheer strength of slope using rock anchors, pinning as well as netting. cost effective approach
