TYPES OF ANTHROPOGENIC IMPACT ON WATER QUALITY IN THE CHEPINSKA AND CHEPELARSKA RIVER BASINS USING WATER QUALITY INDICES AND AIRBUS DEFENCE AND SPACE PLEIADES-1A AND SPOT 6 SATELLITE DATA
Abstract
The aim of this work is twofold: to identify the dominant types of anthropogenic impact on SWQ in the Chepinska and Chepelarska River basins to localise the hot spots of pollution; and to obtain the main land cover units from Very High Resolution (VHR) Airbus Pléiades-1A and SPOT 6 imagery. The assessment of anthropogenic impacts on SWQ is based on an analysis of more than 10 physicochemical parameters, and the CCME WQI, WAWQI, and HPI indices were used. The results show different types of water pollution in the two river basins. In the Chepinska River, the predominant pollution is domestic, caused by untreated wastewater from the sewer systems of populated areas and by numerous illegal solid waste disposals. In the Chepelarska River, mixed type of water pollution is observed. In the upper and middle part of the river, domestic pollution predominates, while in the lower reach, industrial pollution prevails. Using Normalised Difference Vegetation Index and Normalised Difference Water Index, the following land cover classes were defined from VHR satellite imagery: sealed, bare land, grassland, low, medium, and high vegetation, and water. Overall, the results can assist the management of water resources in the pilot river basins. They highlight the potential of Airbus Pléiades-1A and SPOT 6 imagery fore precise land cover mapping.
