The variety of urban landscapes, especially of urban green spaces provide a wide range of human well-being opportunities, physical recreation, sport activities, and urban heat mitigation. Therefore, there are many studies applying remote sensing and GIS methods, which were related to the sustainable city development focused on the “green network”, “green spaces” and land use. Conversely, illegal landfills in and around settlements and rivers have a negative anthropogenic impact on the environment. Therefore, their study is crucial for sustainable planning and landscaping. In this work, the study on urban landscape units and illegal landfills in the Velingrad City, Bulgaria is presented. The following main urban landscape units (ULU) were identified using remote sensing and GIS techniques for calculation of several vegetation and built-up indices from Sentinel 2A satellite imagery (Date: 2023-02-14) and Mean Shift segmentation: 1. Green areas; 2. Residential area/ Impervious surface; 3. Industrial area; 4. Stadium; 5. Broad-leaved forest; 7. Coniferous forest; 7. Mixed forest; 8. Grass/ Pasture/ Shrub; 9. Arable land; 10. Complex cultivation patterns/ significant areas of natural vegetation; 11. Water body/ River Bank Trees; 12. Lake, and 13. Bare Earth/ Paths. The illegal dumps have been investigated in the summer of 2023. The results show that the main types of unregulated landfills in the city of Velingrad are household, construction/ industrial and plastic waste. They are distributed in the river and the riverside, near construction areas, hotels and restaurants, as well as in Lake Kleptuza, and most of them can be cleaned, re-cultivated and landscaped. The methodological approach and obtained results in this work will be further used to elaborate models of anthropogenic impact at river basin scale.
