The Ganga River (known internationally as the Ganges) is one of world's most prominent rivers, running from Himalayas to Bay Bengal and supporting livelihoods > 40 % India's 1.4 billion population. regionally globally important, agriculture industry, yet faces potentially detrimental water quality challenges arising runoff discharge increasing urbanization, industry agriculture. A ∼ 2700 km longitudinal survey nutrient microbial quality, including phytoplankton composition, was undertaken in November 2019. aim investigate if how anthropogenic activities (e.g. urbanisation, agriculture) tributary convergence (potentially reflecting both human activity flow influences) affect shift physicochemical, nutrient, parameters along river continuum. Segmented regression identified four zones distinct nutrient/microbial characteristics River, with breakpoints located near Kanpur, Varanasi downstream Farakka Barage, at distances 1020, 1500 2350 Himalayan source.

Patna is among the cities high populated at risk of ecological and environmental deterioration due to a variety human activities, such as poor land cover management. One most crucial elements successful resource management plan evaluation Land Use Cover (LULC). Over past 20 years, our planet's resources have undergone substantial changes rapid development. The (LULC) categories Urban Agglomeration (PUA), including water bodies, agricultural land, barren built-up areas, vegetation, were identified using Geographic Information System (GIS) techniques. Three multi-temporal images analyzed classified through supervised classification maximum likelihood method. By comparing three separately created LULC categorized maps from 1990 2024, temporal analyzed. In order update or manage natural resources, it vital use change detection tool identify in over time PUA, between 1990, 2010 2024. According their respective Kappa coefficients, accuracy rates for 2024 are 91.66 94.93, respectively. An was conducted determine correctness system efficacy maps. hundred reference test pixels identified. There been found significant built up area has increased doubled last thirty-four years timeline.

Abstract The Saryu River, a branch of the Sharda River (downstream Mahakali River), flows in Kumaon Himalaya. This study utilized physico-chemical parameters to assess water quality status and calculate Water Quality Index (WQI), as well Sentinel-2 satellite images 10-meter resolution for 2022 2023 analyse land use cover (LULC). secondary data was obtained from Uttarakhand Pollution Control Board. results revealed that total hardness, calcium, magnesium, faecal coliform, coliform were beyond acceptable limits set by Bureau Indian Standards/World Health Organization. Ions are primarily released via process carbonate weathering. In both seasons 2023, concentration analysed cation anion followed sequence calcium > magnesium sodium potassium, sulphate chloride fluoride nitrate-nitrogen, respectively. years, WQI showed good quality. LULC shows negative change detection (-0.31%), built area (-0.84%) rangeland (-0.98%), whereas trees (+ 1.05%), crops 0.39%) bare ground 0.69%) show positive 2023. According study's findings, is safe drinking. However, presence highlighted need enhanced sanitary infrastructure protocols mitigate bacterial contamination river water.
