The present study investigates soil erosion in three river basins in Cluj County, Romania, using the Intensity of Erosion and Outflow (IntErO) model. Soil erosion is a growing concern in regions with significant agricultural activities, as it leads to loss of fertile soil, reduced agricultural productivity, and environmental degradation. The selected basins, located in hilly areas with varied land use, provide diverse settings to examine erosion dynamics and sediment yield influenced by factors like rainfall, soil type, land cover, and slope.
The study assesses erosion intensity and maximum water outflow in each basin, focusing on how land use and topography impact erosion rates. Results indicate that erosion severity varies across the basins, with Chinteni showing the highest soil loss rates due to extensive ploughlands and limited forest cover. The model identifies the Chinteni basin as more prone to erosion, highlighting that specific land use practices, such as deforestation and agriculture on slopes, exacerbate soil loss. By contrast, areas with higher forest cover show reduced erosion, suggesting that vegetation plays a protective role.
The findings of the study offer valuable insights for developing soil conservation strategies in Cluj County. Using the IntErO model, policymakers can better understand erosion-prone areas and implement targeted measures, like afforestation and sustainable land management, to minimize soil degradation. This research underlines the importance of integrating land use planning and conservation practices to mitigate soil erosion and protect water resources, ensuring long-term environmental sustainability in the region.
