Kriging interpolation of precipitation for Lake Ćelije catchment

Abstract

The research analyzed the necessary conditions for the successful application of the Kriging method of spatial interpolation for the purposes of average annual precipitation interpolation on a certain area. The Kriging method is widely used in the field of interpolation of spatially distributed data, which also includes rainfall data. The paper analyzes the influence of the number of rainfall gauging stations, as well as model parameter adoption, on the results of spatial interpolation of precipitation. Precipitation interpolation was performed for the experimental catchment of Lake Ćelije, which is located on the Rasina River in the Republic of Serbia. The conducted research presents conclusionson on the influence of the number of rainfall gauging stations on the interpolation results, as well as the suggestions for the practical application of the mentioned method for the needs of spatial interpolation of average annual precipitation on a cathcment.
