Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

The primary objective of this study is to investigate the spatial structure of soil hydraulic properties, specifically soil water retention parameters and hydraulic conductivity, within a portion of the Pavanje river basin. The study aims to develop a methodology for estimating these properties across an entire region using geostatistical techniques, particularly Kriging interpolation. The study also seeks to assess the accuracy of Kriging interpolation by comparing it to other interpolation methods.

• Spatial variation of soil hydraulic properties
• Application of geostatistical methods (Kriging) for soil hydraulic property estimation
• Development of surface maps of soil hydraulic properties
• Comparison of Kriging interpolation with other interpolation methods
• Utilization of soil hydraulic property maps for applications in irrigation design, landscape modeling, and precision farming
