The Ganga's unique and numerous virtues appear to be based on myths, but the reasons for its importance are traceable to scientific premises. The Ganga, symbolizing Indian culture and civilization, is regarded by the Hindus as the holiest amongst the rivers, and it is the Indo-Gangetic plain's most significant river owing to its mighty basin and course, and extraordinarily high self-purifying powers. The Ganga originates from Gangori in the Uttrakhand Himalayan glacier as an upland stream, emerges as a river of the plains at Rishikesh, and, after traversing almost the entirety of India from West to East, finally merges into the Bay of Bengal.

Abstract The variations in pH and Dissolve Oxygen (DO) concentrations were analysed in surface river water samples for three seasons Pre-Monsoon, Monsoon and Autumn (January to December 2022) for four major rivers Ganga, Yamuna, Gomti and Hindon flowing through Uttar Pradesh, India. For river Ganga pH range varied from 7.65 to 8.47 and DO varied from 6.4mg/l to 9.26mg/l. For river Yamuna pH range varied from 7.31 to 10.5 and DO varied from 0 to 8.1mg/l. Gomti river showed, pH range between 7.2 to 8.48, while DO varied from 0.63mg/l to 8.4mg/l. For, river Hindon, pH varied from 6.8 to 7.66 and DO observed was between 0 to 1.8mg/l. Correlation Matrix showed a significant weak positive correlation between pH and DO for all three seasons for rivers Ganga and Yamuna, while river Gomti showed a significant weak positive correlation in Pre-Monsoon and Monsoon season, and a weak negative correlation in Autumn lastly river Hindon showed weak negative correlation between pH and DO for Pre-Monsoon, and Monsoon and a weak positive significant correlation for Autumn season. Dissolved Oxygen was found in good concentration in river Ganga, and almost nilfor river Hindon. An increasing trend line for DO was observed for rivers Ganga and Yamuna while river Gomti showed a constant trend line lastly river Hindon showed almost nil DO. This study helped to identify the variations of pH and DO, and also to find the correlation between them for Pre-Monsoon, Monsoon and Autumn seasons for the river water samples. The study will prove helpful for designing of water treatment plants accompanying seasonal variations.

Abstract. The Himalayan region are home to the world’s youngest and largest mountains, and origins of major rivers systems of South Asia. The present work highlight the importance of remote sensing (RS) data based precipitation and terrain products such as digital elevation models, glacier lakes, drainage morphology along with limited ground data for improving the accuracy of hydrological and hydrodynamic (HD) models in various Himalayan river basins such as Upper Ganga, Beas, Sutlej, Teesta, Koshi etc. The satellite based rainfall have mostly shown under prediction in the study area and few places have are also showing over estimation of rainfall. Hydrological modeling results were most accurate for Beas basin, followed by Upper Ganga basin and were least matching for Sutlej basin. Limited ground truth using GNSS measurements showed that digital elevation model (DEM) for carto version 3.1 is most accurate, followed by ALOS-PALSAR 12.5 DEM as compared to other open source DEMs. Major erosion and deposition was found in Rivers Bhagirathi, Alakhnanda, Gori Ganga and Yamuna in Uttarakhand state and Beas and Sutlej Rivers in Himachal Pradesh using pre and post flood DEM datasets. The terrain data and river cross section data showed that river cross sections and water carrying capacity before and after 2013 floods have changed drastically in many river stretches of upper Ganga and parts of Sutlej river basins. The spatio-temporal variation and evolution of glacier lakes was for lakes along with GLOF modeling few lakes of Upper Chenab, Upper Ganga, Upper Teesta and Koshi river basin was done using time series of RS data from Landsat, Sentinel-1 and Google earth images.

Present study on fishing methods in the upper Ganga River system was conducted during the period 2010-2012. Upper Ganga river system consists of two major rivers basins viz. Alaknanda and Bhagirathi rivers and number of their 1st and 2nd order tributaries which flows through Garhwal region (Central Himalaya). This large network of fluvial water resources harbours rich Ichthyofaunal diversity. The varied potential of fish resources from these water bodies permits the utilization of wide array of fishing methods. Most of the fishing methods of the Garhwal region are primitive, based on indigenous traditional knowledge and well suited to turbulent nature of the streams. In present study eighteen fishing methods and gears have been documented from the upper Ganga River system. Study observed season, habitat and species specificity of the fishing methods. The utilization of crude and unscientific fishing methods is frequent in the streams of remote areas resulting into decline in fish resource. All the fishing methods employed in upper Ganga River system are classified into four types. The classification is based on their utilisation up to the level which will allow the sustainable harvesting and proper management of valuable fish resources.

Abstract: The present route of Budhi Ganga starts from Ishaqwala and reaches Hastinapur via Saifpur Firozpur.Based on preliminary survey, the Budhi Ganga starts from Ishaqwala. On the old road, we still get to see many ancient temples such as Siddha Peeth Shiva temple in Saifpur Firozpur, Pandeshwar temple in Hastinapur, Karna Ghat temple and Draupadi Ghat temple, maybe even as far as Garhmukteshwar many more temples find in the way. The ancient route of the Ganges in Saifpur Firozpur was spread over a considerable area, the evidence of which is present even today. In this research paper, many small evidences including these facts have been presented, which may not have been done in the past. Keywords : Dewal , Ishaqwala , Budhi Ganga, Hastinapur

Life of Living organism have present on the earth depends on Water. Water Quality is also equally important as Water. Ganga river is fulfilling the needs of water of a large population of India. Being a citizen of India it’s our responsibility to keep the Ganga River neat & clean. A large number of governments funded base stations available for forecasting the Water Quality of ganga river. But there is a need of low-cost prediction techniques of water quality based on data available from these base stations. It can help the government to take the necessary decisions to cure the water quality of Ganga River & save the lives of many livings’ organism depends on Ganga River. Monitoring & forecasting of water quality of Ganga River is most important because ganga river is the main source of drinking water of a large population of India. In this paper two time series-based models such as Auto-Regressive Integrated Moving Average (ARIMA), Seasonal ARIMA (SARIMA) have been used to predict the water quality of Ganga River. The models are developed on water quality data available of 10 base stations on the Uttarakhand Pollution Control Board’s official website. Four water quality parameters-Temp, pH, DO, BOD data is used for models training & calculating WQI (Water Quality Index). The result of experiment shows that SARIMA model predict the water quality parameters as well as Water Quality Index (WQI) more accurately.

Abstract Rivers provide innumerable ecosystem services to mankind. However, anthropogenic activities have inflicted a host of pressures to the riverine ecosystems. Climate change is also one of the human induced consequences which is of serious concern. A number of studies have predicted devastating effects of climate change. In the Indian context, where a river such as the Ganga is already suffering from industrial and municipal waste disposal, unhygienic rituals, and other activities, effects of climate change may further aggravate the situation. Climate change will not only result in disasters, but effects on water quality, biodiversity, and other ecological processes also cannot be denied. In this paper, an attempt has been made to evaluate the effects of climatic change on the dynamics of River Ganga. The study focuses on the impacts on fundamental ecological processes, river water quality, effect on species composition, and hydropower potential etc. The paper also discusses management aspects and research needs for rejuvenation of the River Ganga.

The River Ganga produces a substantial amount of its fish from small native species, defined here as those with a maximum length of 25 cm. The FiSAT program was utilized to estimate stock assessments of four important small indigenous species from the River Ganga: Johnius coitor, Cabdio morar, Salmostoma bacaila, and Gudusia chapra. Fish samples were collected monthly for a year (April 2020–May 2021) from four predetermined sampling sites along the River Ganga (Farakka, Berhampore, Balagarh, and Tribeni) in West Bengal, India. The estimated exploitation rate for Johnius coitor, Salmostoma bacaila, and Gudusia chapra was relatively lower than the optimum level of 0.5 and considerably lower than Emax values, indicating that their stocks are experiencing low fishing pressure in the region. The FiSAT results indicated that the species Cabdio morar was found to be heavily exploited. The total mortality (Z), natural mortality (M), and fishing mortality (F) rates for all four of the SIF species were examined, and they were contrasted with data from previous studies. On the lower stretch of the River Ganga, all of the fish stocks are optimally exploited (Eopt), except for the species Cabdio morar. The population dynamics of all of the species have been described for the first time on the lower stretch of the River Ganga. According to the findings, all of the fish stocks throughout the lower stretch of River Ganga are optimally exploited (Eopt), except for Cabdio morar. The study also emphasizes the importance of increasing sustainable fishing efforts, focusing on SIFs throughout the lower stretch of the River Ganga in order to safeguard the livelihood and nutritional status of fishermen.

River Ganges (locally called as river Ganga) is one of the most scared rivers in India. The river is symbol of hope, faith and is worshipped for its wholesomeness due to its purity and sanctity. Pollution of river water due to anthropogenic activity is a very common issue worldwide. Similarly, river Ganga pollution in India throughout its entire courses, is a major concern due to city outfalls. This river, also named as river Hooghly in West Bengal, India, is exposed to outfalls carrying domestic wastewater of its both bank and their distribution in river Ganga is strongly influenced by season and tide. This study aimed to generate an idea of distance and direction wise changes of concentration of pollutants in wastewater in river Ganga. During 2014, the selection of five major outfalls was done by considering Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), heavy metals, total fecal coliform level, and the study continued for next four consecutive years to find out the influence of tide and season. Geographical Information System (GIS) based maps provided a better reflection of these changes. Student’s t-test highlighted the significant changes in concentration of parameters season wise. A significant higher value of DO, BOD, nitrate nitrogen, and chloride were found in pre-monsoon season compared to monsoon season. Regression Equation generated for highly correlated parameters (coliform and heavy metals) helped to predict the level of one parameter with others. The zone of influence of BOD, DO, phosphorus and nitrate nitrogen from each of the five selected outfalls was very prominent. Acoustic Doppler current profiler at two of the five outfalls helped to estimate strip-wise depth average discharge which helped to estimate the value of water quality parameters by Plug Flow Model during high tide and low tide. A strong tidal variation was observed during low tide. This study helped to predict the influential zone from outfalls which will help to generate an alternative solution of river water use. This approach can be applied globally to prepare river water usage guidelines.

82 km stretch of River Ganga from Garhmukteshwar to Narora has been declared as Ramsar site because it inhabits rare and endangered Gangetic dolphins (Platanista gangetica). Dominance of Molluscs and Annelida communities of benthic macroinvertebrates provide proper feeding habitat for dolphins at more than 10-20 meter depth in River Ganga. Gangetic dolphin preferred a high level of flow velocity in River Ganga at Garhmukteshwar. Dolphins were commonly observed in biological water quality of moderate pollution (Class ‘C’). Habitat degradation due to construction of dams/ barrages, extraction of water, siltation, pollution due to hazardous chemicals and other human activities are the main causes of its decline in the river.

Biological monitoring is an essential element to assess the environmental health of aquatic biotopes. Any stress imposed in aquatic ecosystem manifests its impact on the inhabitant communities and result in restructuring the present biotic components. The present study is an effort to assess the impact of damming of river water on the physico-chemical characteristics and their relations to planktonic population of Ganga river. Results indicated remarkable changes in some physico-chemical factors in upstream and downstream of Ganga river at Pashulok barrage. Rich planktonic concentration were observed as 1273.67 ± 598.124 and 1184.25 ± 588.724 units/l in the upstream and downstream section respectively. Phytoplankton always dominated (88.4 to 91.7%) over zooplankton and mainly constituted by Bacillariophyceae (65.07-78.95%) followed by Chlorophyceae (25.34-17.14%) in Ganga river.

The Ganga River is one of India's biggest and most significant rivers, and the health and welfare of millions of people depend on the purity of its water. The traditional linear models that have been used extensively to assess water quality have limitations in their ability to capture the intricate non-linear interactions between the water quality factors. On the other hand, non-linear data analytics are able to identify these linkages and can offer more precise and trustworthy estimates of water quality. In order to monitor the River Ganga's water quality, this study suggests a non-linear data analytics approach that entails gathering and studying a significant amount of water quality data. The results show that the proposed approach outperforms traditional linear models and can provide valuable insights into the water quality of the River Ganga.

Despite the country’s extensive environmental jurisprudence and many historic rulings in which the courts have rescued worsening environmental situations, river (Ganga and Yamuna) water does not match the mandated minimum “bathing quality.” Rivers like the Ganga and Yamuna, which flow through numerous states and towns, would be in a different situation. Without strict monitoring and enforcement of the measures, no action plan can work. Punishment of defaulters can serve as deterrence while also instilling fear in other non-compliant enterprises. In comparison to environmental legislation, the NGT Act allows for substantially harsher fines and penalties. River rejuvenation plans must be carefully monitored to ensure that they do not suffer the same fate. Making action plans will not improve river water quality unless they are implemented with sincerity and consistency, as well as continuous monitoring and severe enforcement.

Rivers in India have been regarded from time immemorial as sacred water bodies. The holy Ganges flowing in the most populated northern India is also declared unfit for even bathing. The present investigation has been carried out to monitor the water quality of river Ganga. Water samples were taken from five different sites and were checked out for microbiological study by evaluating SPC. Later on enumeration, isolation and identification of bacteria was done. Sensitivity tests were also carried out. The results obtained after performing the experiments indicates that the water in the tested stretch is unfit for both bathing and drinking purposes.

Ganga is the most prestigious river of India. The COVID-19 lockdown may have forced us to stay indoors, but it has been boon for pollution-ridden Ganga and Yamuna. Plankton is tiny organisms drifting with water current, influenced by river physical and chemical factors. During lockdown anthropogenic factors were reduced which affected water and plankton quality. Plankton samples were collected from the upstream of the river Ganga (Shankerghat, latitude 25030’28” N and longitude, 81052’10”E) and Yamuna (near boat club, latitude 25024’29”N and longitude 81054’50”E) at Prayagraj, during national lockdown. In the before lockdown period (2019), total 28 planktonic taxa were recorded from the river Ganga, among them 10 taxa from Bacillariophyceae, 15 from Chlorophyceae and 3 from Myxophyceae. While during LD period total 54 genera with 86 species was recorded (Bacillariophyceae 10 taxa, Chlorophyceae 23 taxa, Myxophyceae 9 taxa, Euglenophyceae 2 taxa, Dianophyceae, 1, Rotiferea 7 taxa, Protozoa 2 taxa). Various species of green algae were observed in this small period of lockdown, some species were not observed since a long, like Pediastrum tetras, Scenedesmus abundans, Ankistrodesmus fusiformis, and Brachionus angularis. Various species of phytoplankton and zooplankton were in reproductive phase because river was flowing silently, without any internal and external disturbance. Ganga was more affected by anthropogenic activity and factory discharge than Yamuna So lack of chemicals in the water and minimum human interference favoured auto rejuvenation of Ganga in terms of plankton quality, diversity and reproduction behaviour. Such type of environmental changes may stimulate for origin of new species and disappear or reappear of various aquatic species.

The Ganga River Dolphin Platanista gangetica Roxburgh, 1801 is a globally endangered cetacean found in the River system of Ganga, Brahmaputra and Meghna in Bangladesh and India. A survey and research were conducted from 2012–2014 to explore the behaviour, abundance, habitat use and potential threats of the Dolphin in the lower, middle and upper stretches of the river Ganga and its tributaries in southern West Bengal. The study recorded different types of surfacing patterns with respect to their age class as well as on diurnal activity pattern of the individual. The adults and sub-adults were found to have different types of surfacing during different hours of the day. The morning and afternoon were observed to be feeding hours of the Dolphin. Multiple potential threats were encountered during the present study such as destructive fishing gears, dumping of solid and municipal waste, industrial effluents, agricultural run-off, construction of water structures, water extraction and reduction of river depth attributed to siltation. These factors contributed to the present study of the river dolphins in the Ganga, which are localised at certain pockets in good number.

River Ganga is the largest river in India. It represents one of the magnificent geographical features of the country. It would be incorrect to confine it to say only as a water body. Nothing can match its everlasting divinity. It has its roots in Indian culture. As the holy river originates from “Gangotri Gomukh” in the country, it speaks much more about the culture, tradition, way of living of people. Since times immemorial, India has been called as the Land of Lords. It has been said to be brought from heaven and therefore it has been always personified as Goddess Ganga. River Ganga is Mother Ganga by all means. Since history enormous literature has been written from time to time about her greatness. Indian literature is largely enriched with her praise and appreciation. The action–oriented ganga offers a wide knowledge and wisdom to the people besides providing its pious water. As it fertiles the soil along the basin, it nourishes the souls and minds. Educating us in many ways and aspects, it gives us an overview of the structure of society. It teaches us how to lead an ideal life while maintaining a calm attitude. It teaches us to fulfil our responsibilities in our work area. Mother Ganga must be viewed with the spectacles of love, respect, emotions and dedication. Therefore, to structure the education in Indian perspectives the cognitive, affective and psychomotor properties of Holy Ganges can be inherited into the education process or it must be said that we should learn from Mother Ganga to become a balanced and an all-rounder personality.

Water of Ganga river is reported to have more than 200 isolates of phages. This study has used the naturally available cocktail of phages in the Ganga water as a treatment for chronic Psoriasis. In the conventional Phage Therapy (PT) phages that are active against specific bacteria are first identified; then isolated, multiplied and administered to the patient. We have made a novel innovation of administering the naturally available cocktail of phages in the water of the Ganga river without first identifying the target bacteria and isolating specific phages that may be active against them. In doing so, we enable the large numbers of phages to self-identify the bacteria that are present and act against them. This approach shortcuts the tortuous process of conventional PT. Further, the phages act against a number of bacteria simultaneously and provide good results in psoriasis which has multiple causes.Patients who took Ganga water for only 2 weeks showed benefit but the benefit did not sustain after stoppage of the treatment and the disease relapsed to the pre-treatment levels. The same patients showed sustained benefit after they took Ganga water for four weeks. Conclusion is that Ganga water can be used for therapeutic purposes as long as the treatment is continued for at least four weeks. The study underscores the need to establish more robust protocol for treatment of dermatological and possibly other diseases with the cocktail of phages available in the waters of the Ganga river.

The study attempts to assess tourists' (international, national and local) perceptions for polluted state of the river Ganga in Varanasi, plausible reasons for present status and their willingness to contribute towards river cleanliness. The Kruskal-Wallis analysis suggests variation in perception for pollution and river reverence across three categories of tourists. Tourists perceived the present status of river to be dirty and urged that it can only be improved by joint efforts of people and government. Further, positive response of tourists was observed for their involvement in cleanliness drive of the river Ganga via their willingness to pay and social activities.

The Gangetic hairfin anchovy, Setipinna phasa (Hamilton, 1822) were collected from river Ganga (Kanpur) and Hooghly estuary (Kolkata) to study the comparative reproductive traits (sex ratio, spawning season, gonado-somatic index, fecundity and egg diameter). Female outnumbered the male in the population of river Ganga but it was non-significant in the population of the estuary. Five maturity stages were identified in males and females of the fish of both ecosystems. Occurrence of multimodal (immature, maturing and mature) and uni-modal (matured) type of ova in the ovary of the fish of Hooghly estuary and river Ganga respectively and the values of gonado-somatic index confirmed the double and single spawning in a year in the fish in estuary and river respectively. The absolute fecundity was found to be higher in the fish of river Ganga compared to that of the estuary (P < 0.05). Linear and positive correlations between fecundity and the total length, body weight, ovary length and ovary weight were noted in the fish of both ecosystems (R2 > 0.90). The present study provides the comparative account of the reproductive and spawning strategies of S. phasa for the first time in favour of the proper management and conservation of the fish.

Trans-boundary Rivers are one of the major causes of conflict among the riparian states. Mathabhanga Churni is one of such 54 shared rivers between India and Bangladesh flowing in the Ganga Brahmaputra river basin which is a major source of fresh water as well as livelihood support to the people of its riverbanks for various reasons. The water quality of Churni deteriorated due to industrial waste disposal by a company, located in Bangladesh, in the river Churni. Moreover, in Indian side there are open defecation in the river Churni along with industrial and municipal waste disposal which are responsible for degradation of water quality affecting the livelihood of the common people of the riverbank of both sides. Initiatives have been taken to revive the course of river and purify its water quality by the National Green Tribunal, local environmental activists, like-minded people and organizations through awareness programme and protest. The article argues that initiatives for revival of the river Churni were taken by local activists and Government agencies but there is an acute absence of trans-boundary attention from both sides. While both the countries are busy with the Teesta and the Ganga as a result diplomatic parleys, government officials seem to have ignored the issue of pollution in the river Churni which can actually act as a catalyst for inculcating trans-boundary water diplomacy. It finds that diplomatic or bilateral engagements, issues revolving around Centre-State relations also need to be addressed in order to prevent an ecological disaster on both sides of the boundary and also to sustain livelihoods.

This study seeks to examine the detection of course change in one of the major rivers of India, that is the Ganga, between the period of 1980 to 2020 and utilizes satellite driven data to demonstrate the visibility of shifting in its course. The purpose of study area is to find out the change detection of the river course. The channel shifting of the river course has been used to demonstrate the historical change in Landsat MSS, TM, ETM, and OLI/TIRS satellite images in the decades of 1980, 1990, 2000, 2010 and 2020. The study exhibits several reasons responsible for and lead to this shift, such as erosion problems and changing characteristics of the Ganga from Rampurghat to Chunar at different cross-section site points. This research area has been divided into six cross-sections, namely, XS-1, XS-2, XS-3, XS-4, XS-5, and XS-6. We attempt to examine how the river’s shape and position have witnessed a change during the 1980–2020 period via using remote sensing and GIS methods. We have identified that the course line of the Ganga has demonstrate a shift via using five types of satellite imagery in the above-mentioned period. The process of channel shifting has included an erosional and a depositional development occurred due to infrastructure damage by sedimentation, flood and changing river course. The Ganga course has shifted towards the south and the north direction places which as a result leads to village erosion. The major aspects of this study have a direct interaction with the physical and socio-cultural environment from upstream to downstream in cross-section. The course change detection of the study has been taken in the context of the river management and planning for future prevention of agricultural land, kuccha houses, food, and economic loss to farmers.

River Ganga arises on the southern slopes of the Indian central Himalayan region beginning the Gangotri glacier. The river covers catchment area of 8, 61,404 km2 and its total length in the state Bihar stretch is 475 km. This study was carried out at Patna in the river Ganga at two sampling sites, viz., Digha Ghat (upstream) and Gai Ghat (downstream). The objective of the study was to observe the eminence of water of Ganga at Patna. The results that indicate that the river reaches near the city of Patna (upstream at Digha Ghat) are less polluted with pH 7.75, DO 7.42 mg/l, BOD 2.48 mg/l and COD 15.12 mg/l, while when the river leaves city after travelling 18 km (downstream at Gai Ghat), concentration of all pollutants increases significantly (pH 6.28, DO 6.22 mg/l, BOD 2 mg/l and COD 23 mg/l). The concentration of coliform bacteria (total coliform ranges from 5000 to 6000 MPN/100ml and faecal coliform ranges from 2200 MPN/100ml and 3000 MPN/100ml at both the sites) was recorded at higher level than the upper limit of the permissible level. This increment may be due to domestic and sewage discharge from the city. The municipality of Patna has sewage treatment plant capacity of about 109 MLD but whereas the city generates approximately 250 MLD sewage/township discharge. For the maintenance of pristine quality of water of the river Ganga, the sewage need be treated before discharge

The article aims to provide insights into the effectiveness of international water treaties in addressing environmental challenges in river basins. The Ganga and Indus River basins, encompassing a vast expanse of 2.20 million square kilometers, serve as the lifeblood for roughly one billion inhabitants of the South Asian region. However, the escalating challenges of water scarcity, climate change, over-extraction, pollution, and reduced flow that stem from burgeoning population growth, urbanization, industrialization, and agricultural activities, have critically endangered the water quality and quantity of these basins. The Ganga and Indus Water Treaties were created to promote collaboration and address water-related environmental issues. However, their limitations in addressing these threats make it necessary to review their effectiveness and examine their gaps and inadequacies. The study examines treaties related to the Indus and Ganga River basins regarding environmental threats, identifying gaps that need attention. A comparative analysis with the UN Watercourse Convention will be conducted to assess their effectiveness and adherence to global standards. Key Words: Environmental threats, IWT, Ganga treaty, UNWC

Considering Ganga River as one of main Holy River in India, millions of people throng to the river to have a holy dip, Aachman (Mouthful of holy water) and cleanse themselves of sins. Magh Mela is a great festival to take place in bank of Triveni (Sangam) at Allahabad and runs more than one and half month, when millions of pilgrims from different regions in India go there for taking a holy bath in Sangam of Ganga. Thus, the bathing in the river during Magh Mela leads to high pollution of the river in comparison to other days such as normal bathing days. This study focused on the water quality status from some selected physico-chemical parameters of River Ganges and the impact of Magh Mela as well as the variation in the river’s flow rate. Results indicate that the pollution load was alarmingly high and the flow of the Ganga had been very poor. Further, the study found that the water was not fit for bathing during the 2012 Magh Mela.

Presence of microscopic algae can cause taste and odour problems, water discoloration, or form large mats that can interfere with boating, swimming, and fishing. The present study was conducted to assess the phytoplankton assemblages which in turn can serve as a suitable method to assess the quality of river ecosystem. Diversity of phytoplankton in river Ganga in Allahabad at five sampling stations was conducted from March to April 2014. Plankton identified in the river mainly composed of the members of Bacillariophyceae, Chlorophyceae and Cyanophyceae families.The Palmer pollution index values were calculated to know the level of organic pollution and to support the data. On the basis of quantitative and qualitative estimates 15 significant algal species were identified which can tolerate high degree of pollution. The abundance of phytoplanktons in april was greater than in march. Abundance of phytoplanktons and algal bloom was maximum at Chhatnag ghat whereas at Sangam low phytoplankton diversity was found.In general, moderate temperature, low current velocity and high transparency of water appear to be better the conditions for algal growth in the river Ganga. These findings highlighted the deterioration of water quality of the river due to industrial, commercial and anthropogenic activities. The status of phytoplankton diversity of river Ganga was quite low indicating that the river is highly polluted.

The Ganga River, a lifeline for millions of people in the Indian subcontinent, is facing significant environmental challenges due to the construction of barrages and various anthropogenic activities along its course. This review paper examines the effects of barrages and human interventions on the ecological integrity of the Ganga and explores current issues surrounding its deteriorating ecosystem. Furthermore, it discusses the restoration efforts undertaken to mitigate the ecological impacts and restore the river's health. The construction of dams and barrages can aggravate the situation in the context of the Ganga, which is already suffering from the discharge of industrial and agricultural wastes. The construction of various dams, barrages, and hydroelectric projects is affecting the water flow of the Ganga. These affect the water flow, resulting in the accumulation of solid waste on the river bed. Barrages not only affect the water flow but also restrict the migration of aquatic fauna. This affects the hydrological balance of the Ganga as well as the survival and existence of several fish species. This review provides a comprehensive analysis of the effects of barrages and anthropogenic activities on Ganga's ecological integrity, sheds light on the current issues plaguing the river, and highlights the ongoing restoration efforts. By understanding the complex interplay between human activities and ecosystem dynamics, stakeholders can work towards safeguarding Ganga's ecological health and ensuring its sustainable future.

The present study was carried out to investigate the comparative seasonal distribution and relative abundance of fish fauna of streams Bachan Gad of river Alaknanda and Kakda Gad of river Mandakini of Mid-himalayan Ganga river System. Total length of the Bachan Gad is 14.5 km from origin to the confluence at main river Alaknanda with an altitudinal variation from 605.94 to 1418.23m (a.s.1), whereas, total length of the Kakda Gad is 15.5 km. from origin to confluence at main river Mandakini with altitudinal variation from 984.50 to 1993.70 m (a.s.1). Total 23 species from Bachan Gad and 20 fish species were identified from Kakda Gad. The differences in the availability of fish-fauna were directly related to the nature of the profile and slope of tributaries; which affects the migration and breeding grounds of the fishes inhabited in the main river Alaknanda and Mandakini of Ganga river system. Variation in the availability of fishes has been recorded from different sites of the stream. In streams and rivers the changes take place along their length is directly related to the eco-physico-chemical nature (water depth, current, substratum etc). All these factors which change along the length of streams are also the factors which control the distribution of the various sections of the biotic fauna and flora.

This paper attempts to evaluate the Malaysian water quality indexing method that has been criticized for its ineffectiveness. The indexing method is referred to as the Water Quality Index of the Department of Environment, Malaysia (DOE-WQI). This index was assessed against two other indices (River Ganga Index and Minimal Water Quality Index (WQImin)) and a modified DOE-WQI was also proposed. DOE-WQI and WQImin are physicochemical indices, whereas the River Ganga Index and modified DOE-WQI are indices with the inclusion of a microbiological parameter. The assessment was conducted based on the water quality of tropical rivers in Malaysia, with specific reference to Sarawak River and its tributaries. Water quality in terms of pH, dissolved oxygen, conductivity, turbidity, total suspended solids, biochemical oxygen demand, chemical oxygen demand, ammoniacal nitrogen, and fecal coliform count (FCC) was measured from 18 stations in December 2015, January 2016, and March 2016. Generally, the river was characterized with high FCC with the four indices significantly correlated. The results demonstrated the shortcomings of the existing DOE-WQI; the physicochemical index assigned water quality to a better class than its actual conditions without taking into consideration the FCC.

River Ganga in India has tremendous self-purification capacity due to its dynamic, turbulent and meandering characteristics. In addition due to the presence of anti-bacterial agents such as Bacteriophages virus killing bacteria and its medicinal properties, the refinement capacity increases. In the present work, water quality samples of river Ganga at Kanpur, Prayagraj, Varanasi, Patna and Bhagalpur were collected and analysed for the years 2017-2019 to assess the change in water quality of the river Ganga in terms of total suspended solids (TSS) and turbidity through remote sensing data and ground observations. The change in spectral reflectance of water along the river in the visible region has been analysed using the Landsat-8 multispectral remote sensing data and water quality samples have been collected from all the sites on the date of pass of Landsat-8 satellite. The results obtained shows that the satellite based remote sensing approach can be effectively used to make qualitative and quantitative estimates of total suspended solids and turbidity using nonlinear equations with high accuracy, even in the absence of field observations.

The Ganga Basin in India experiences problems related to water availability, water quality and ecological degradation because of over-abstraction of surface and groundwater, the presence of various hydraulic infrastructure, discharge of untreated sewage water, and other point and non-point source pollution. The basin is experiencing rapid socio-economic development that will increase both the demand for water and pollution load. Climate change adds to the uncertainty and future variability of water availability. To support strategic planning for the Ganga Basin by the Indian Ministry of Water Resources, River Development and Ganga Rejuvenation and the governments of the concerned Indian states, a river basin model was developed that integrates hydrology, geohydrology, water resources management, water quality and ecology. The model was developed with the involvement of key basin stakeholders across central and state governments. No previous models of the Ganga Basin integrate all these aspects, and this is the first time that a participatory approach was applied for the development of a Ganga Basin model. The model was applied to assess the impact of future socio-economic and climate change scenarios and management strategies. The results suggest that the impact of socio-economic development will far exceed the impacts of climate change. To balance the use of surface and groundwater to support sustained economic growth and an ecologically healthy river, it is necessary to combine investments in wastewater treatment and reservoir capacity with interventions that reduce water demand, especially for irrigation, and that increase dry season river flow. An important option for further investigation is the greater use of alluvial aquifers for temporary water storage.

Abstract. Accurately quantifying sediment fluxes in large rivers draining tectonically active landscapes is complicated by the stochastic nature of sediment inputs. Cosmogenic 10Be concentrations measured in modern river sands have been used to estimate 102- to 104-year sediment fluxes in these types of catchments, where upstream drainage areas are often in excess of 10 000 km2. It is commonly assumed that within large catchments, the effects of stochastic sediment inputs are buffered such that 10Be concentrations at the catchment outlet are relatively stable in time. We present 18 new 10Be concentrations of modern river and dated Holocene terrace and floodplain deposits from the Ganga River near to the Himalayan mountain front (or outlet). We demonstrate that 10Be concentrations measured in modern Ganga River sediments display a notable degree of variability, with concentrations ranging between ∼9000 and 19 000 atoms g−1. We propose that this observed variability is driven by two factors. Firstly, by the nature of stochastic inputs of sediment (e.g. the dominant erosional process, surface production rates, depth of landsliding, degree of mixing) and, secondly, by the evacuation timescale of individual sediment deposits which buffer their impact on catchment-averaged concentrations. Despite intensification of the Indian Summer Monsoon and subsequent doubling of sediment delivery to the Bay of Bengal between ∼11 and 7 ka, we also find that Holocene sediment 10Be concentrations documented at the Ganga outlet have remained within the variability of modern river concentrations. We demonstrate that, in certain systems, sediment flux cannot be simply approximated by converting detrital concentration into mean erosion rates and multiplying by catchment area as it is possible to generate larger volumetric sediment fluxes whilst maintaining comparable average 10Be concentrations.

The Bangladesh lowlands are traversed by the largest sediment flux on the planet. Detritus generated mostly in Himalayan highlands and conveyed through the Ganga–Brahmaputra rivers and Meghna estuary reaches the Bay of Bengal, where it forms a composite deltaic system. This study integrates the vast existing database on Ganga–Brahmaputra sediments of all grain sizes from clay to sand with new petrographic, mineralogical, and geochemical data on estuarine and shallow-marine sands. A large spectrum of compositional signatures was used to: (i) assess the relative supply of the Ganga and Brahmaputra rivers to estuarine and shelfal sediments; (ii) define the compositional variability of estuarine sediments and the impact exerted by hydraulic sorting and climate-related chemical weathering on provenance signals; (iii) define the compositional variability of shelf sediments and the potential hydrodynamic segregation of fast-settling heavy minerals in coastal environments and of slow-settling platy micas on low-energy outer-shelf floors; (iv) consider the potential additional mud supply from the western subaerial part of the delta formerly built by the Ganga River; and (v) draw a preliminary mineralogical comparison between fluvio-deltaic sediments and turbidites of the Bengal–Nicobar deep-sea fan, thus tracing sediment dispersal across the huge sedimentary system extending from Tibet to the equatorial Indian Ocean. All investigated mineralogical and geochemical parameters, as well as Sr and Nd isotope ratios and clay–mineral assemblages, showed a clear prevalence in sediment supply from the Brahmaputra (60–70%) over the Ganga (30–40%). Heavy-mineral suites and Sr and Nd isotope fingerprints of Bengal shelf sediments are nearly identical to those of the Brahmaputra River and Meghna estuary, also because the Brahmaputra carries almost twice as many Ca-plagioclase grains and heavy minerals including epidote than the Ganga, and these minerals control the large majority of the Sr and Nd budgets. The experience gained in modern settings can be directly extrapolated only to the recent past, because sediments older than the late Pleistocene and buried more than a few hundred meters begin to lose less durable ferromagnesian minerals by selective chemical dissolution, which makes quantitative estimates progressively less robust in more deeply buried older strata.
