(ii) Evaluation of the quantities and characteristics of all the embankment construction materials available within a reasonable distance of the dam site.
(iii) A study of all the factors which may influence the design. (iv) The selection of trial designs.
(v) Analysis of the safety of the trial designs.
(vi) The modification of the designs to satisfy the minimum stability requirements. (vii) The preparation of detailed cost estimates.
