Improvement of the method of ordinary kriging of geostatistical analysis for modeling water quality in the river taking into account its sinuosity

Abstract

The method of ordinary kriging of geostatistical analysis is improved for the modeling of quality of waters of rivers taking into account their sinuosity due to the account of distance along the flow of the river between observation of surface water quality in determining the weights used in the algorithms of interpolation geostatistical analysis. The improvement of this method was confirmed at modeling of surface water quality on the example of the Southern Bug River in the town Ladyzhyn, enabling reduction of interpolation error on more than 14 %.
