Defining the functional dependence of the hydraulic parameters of the water supply system is crucial because it enables the calculation of unknown values based on the appropriate available or measurable values. „Spline“ interpolation is one of the methods by which it is possible approximately, but with sufficient accuracy, to define the functional dependence of hydraulic parameters if we have known values at certain characteristic intervals that can be measured or calculated by one of the numerical methods. "Spline" interpolation denotes the method of constructing a function within the range of a discrete set, which approximates the already known points. The result is a function, or set of functions, by which it is possible to calculate the value of an unknown function for any value of the variable at a defined interval. The specific application of this method will be shown on the example in this paper.
