Assessing the impact of land use and land cover on river water quality using water quality index and remote sensing techniques

Assessment of hydrogeochemistry in groundwater using water quality index model and indices approaches

“…These results suggest that the groundwater exhibited a slightly alkaline nature, and all samples were found to be within the acceptable range of 6.5–8.5. The slightly alkaline nature indicates that the water could be attributed by the loss of CO 2 , and the rainfall and dissolution of minerals from within the basalt [ 88 ]. The average value of EC observed high during the wet season (749 μS/cm) in comparison the dry season (672 μS/cm) ( Fig.…”

“…The cutting-edge geographical information system (GIS) was employed in accordance with established procedures of Ref. [ 88 ]. Details of the procedures can be found in Ref.…”

Impacts of seasonal variations and wastewater discharge on river quality and associated human health risks: A case of northwest Dhaka, Bangladesh

“…The average precipitation of the region is 74.11 mm annually [ 32 , 33 ]. This geographical area's predominant land use patterns are depressions, agricultural lands, and settlements [ 34 , 35 ]. Treated and untreated effluents are directly discharged from the industrial estate into the river.…”

Identification of surface water quality pollution areas and pollution sources based on spatial clustering and random forest in Henan, China

“…This paper takes Nanyang City as a model city for the lightly pollution areas, which is located in the Yangtze River Basin and has high-con dence and high-quality surface water. Surface water quality is signi cantly affected by urbanization and land use change (Gani et al, 2023). This paper analyzes the sources of pollution in heavily polluted areas (Zhengzhou, Kaifeng, Luoyang) by comparing the land use, urbanization and industrial structure between heavily polluted areas and lightly polluted areas.…”
