To the applicability of radial basics functions for the interpolation of short term rainfall scaling exponents in Slovakia

Year, pages: 2016, 243 - 251

In practice, we are often faced with the problem of reliable estimation of design short term rainfall intensities on places without observations, respectivelz with insufficientlz long time series of observations, for engineering design. This problem can be solved for example using regionaliyation methods that allow the use of available spatial information and thus, out of direct observation to achieve reliable estimates of design values. In this studz, we propose an alternative method to estimate the design short=term rainfall intensities on places without direct observation. We applied an indirect estimation method based on scaling exponents which were interpolated using method based on radial basis functions. This approach has not zet been applied to such tasks. The aim of the present studz was therefore to test the suitabilitz of this method in condition of Slovakia. We selected í+ precipitation stations from all over Slovakia, were we derived scaling exponents of short=term rainfall for the warm period of the zear. The scaling exponents were then interpolated bz using the Hardz Multiquadratic Method throughout Slovakia. The results of interpolated estimates were compared with the statistical estimates at the stations, and showed great consistencz with them.
