Consider the following statements about the stability criterion of a gravity dam.

Statement I: If the force of friction is more than the force due to water pressure, the dam is safe against sliding.

Statement II: If the resultant of the weight of the dam and the horizontal force due to water pressure lies outside the base of the dam, but within h (h = height of the dam) from the face of the dam, the dam is safe against overturning.

Statement III: To avoid tension at the base of the dam, the maximum value of eccentricity is b/6 on either side of geometrical axis of base section. Where, b is base width of dam. Which of the given statements is/are correct?
