Methodology Update for Determination of the Erosion Coefficient (Z)

Summary/Abstract: The results show the justified use of the regression models in the process of determining the erosion coefficient (Z), and are essentially a replacement for the tables created by R. Lazarević in the "New procedure for determining the erosion coefficient Z" (Lazarević, 1985). By analysing the correlation of the results obtained by the regression models and results obtained during the mapping of erosion in the Republic of Srpska, the coefficient of determination R² = 0.9963 was determined (y = 0.9963x +0.0012), which is essentially a good assessment of the obtained models. Of course, this analysis and the development of regression models included only those variables that R. Lazarević analysed in his procedure for determining the erosion coefficient Z, and did not include variables X and Y because they were already contained in the coefficient of the erosion type Φ, that is, it was determined on the basis of the previous two variables data. Performed updating of the existing methodology will greatly contribute to easier and faster determination of the erosion coefficient (Z), and the results obtained have been fully quantified, thus avoiding the subjective errors that arise as a result of qualitative assessment and analysis.
