STUDY OF THE MAIN PARAMETERS DETERMINING THE PREDICTION OF WATER EROSION OF MOUNTAIN SLOPES
Abstract
In order to predict water erosion processes on mountain slopes in the mountainous and foothill landscapes of Georgia, in May and September of 2024 a field scientific study was conducted in the ecosystems of Chiatura Municipality. As a result, five erosion-sensitive sites were selected, for which GPS coordinates and absolute heights above sea level were recorded and plotted on a digital map. Longitudinal and transverse profiles were made at the selected sites, and soil samples weighing up to 3 kg were collected. Ten samples were delivered from the field for laboratory geological and chemical analysis to determine the granulometric composition and fertility of the soils. A polygon was also selected in the village of Kveda Chala in Chiatura Municipality to create a field test polygon for determining erosion processes. After processing the samples by sieving, the average diameter of soil particles was determined, and integral granulometric curves were constructed. After determining the geological, topographical, climatic, and hydrological characteristics of the territory, the water erosion coefficient of mountain slopes was determined, taking into account the degree of soil damage and erosion class indicators.
