The effect of groundwater on the engineering behaviour of soils and rocks is of fundamental importance, indeed to paraphrase Tergazhi — without water there would be no soil mechanics. This paper reviews these effects in terms of the variation in the properties and behaviour of soils and rocks brought about by changes in moisture content, and associated changes, notably in effective stress, and by the dissolution of parts of the rock or soil mass.
