The paper dealt with the analyses of the flow nets within hydraulic fill dams used for the disposal of finely-crushed mine ore. Certain aspects of the paper, however, applied to other earth dam problems and to the flow of water into drainage trenches. It was also shown how, by means of given formulae and curves, it is possible to estimate the discharge through a dam as well as certain other geometric properties of the flow net, without drawing the flow net for the dam.
This paper gives a brief outline of the theory of consolidation followed by a descriptionption of the existing methods of calculating the coefficient of consolidation from experimental results, with a discussion of the relative merits of these methods. A simplification of one of the methods follows as well as a new numerical method evolved by the Author. Finally, a worked example is given to illustrate the various methods of making the calculation.
