Abstract
In the ongoing research a topological interpolation method was elaborated over the N -1 dimensional space of the grading curves – represented by a N -1 dimensional simplex - using c N 2 data. The surface is selected on the basis of the grading entropy concept and the interpolated function is extended to the whole simplex by the grading entropy map. In this paper the method is further developed. The extended method is illustrated using the examples of the dry density and the parameters of the van Genuchten soil water retention function.
