Mathematical modelling of erosion processes in the Middle Zarafshan highland plains

This article delves into the mathematical modeling of erosion processes affecting the Oktov mountain plains in the Middle Zarafshan Region, a geomorphologically intricate and relatively inaccessible terrain. By utilizing high-resolution satellite imagery, the study aims to enhance the understanding of erosion dynamics in this geomorphologically complex area, where traditional ground-based observations are challenging. Satellite images are processed and analyzed to extract critical data on topographical changes, sediment displacement, and vegetation cover, which are vital indicators of erosion activity. Satellite-derived metrics—such as digital elevation models (DEMs), normalized difference vegetation index (NDVI), and sediment transport estimates—are synthesized to quantify erosion susceptibility. The mathematical models developed in this study are grounded in multivariate geostatistical techniques and erosion prediction equations akin to the Revised Universal Soil Loss Equation (RUSLE), adapted for remote sensing applications. The model employs algorithms that account for various erosive factors such as rainfall intensity, soil composition, slope gradient, and land use practices. The model was validated using ground truthing, ensuring their robustness and accuracy in predicting erosion trends. Through a combination of spatial analysis and numerical simulations, the research identifies the most vulnerable areas to erosion and provides insights into the underlying mechanisms driving these processes. It underscores the significant impact of both natural and anthropogenic factors on the erosion dynamics of the Oktov mountain plains. The findings delineate erosion-prone zones and correlate intensification patterns with both natural gradients and unsustainable agricultural practices, echoing concerns raised in contemporary erosion literature regarding land degradation in semi-arid upland systems.
