- Description
- A transfer function describes the relation between the grading curve and some physical property or physical property function of a soil. It can not be determined empirically due to the large number of possible grading curves. To overcome this difficulty, a double interpolation technique is suggested based on some measured data and the grading entropy concept. The first interpolation is made in the grading entropy diagram on the basis of some "optimal" grading curve data. The so-determined preliminary transfer function is then extended onto the inverse image of the entropy diagram points by a second interpolation or by a curve-fitting technique. In this paper, a double interpolation method to find a transfer function to predict the soil water retention curve for well-graded sands from soil grading data is described. An experimental program and measured data to validate the method is also presented.
