Climate change and extreme weather events (such as droughts, heatwaves, rainstorms and floods) pose serious challenges for water management, in terms of both water resources availability and water quality. However, the responses and mechanisms of river water quality under more frequent and intense hydroclimatic extremes are not well understood. In this Review, we assess the impacts of hydroclimatic extremes and multidecadal climate change on a wide range of water quality constituents to identify the key responses and driving mechanisms. Comparison of 965 case studies indicates that river water quality generally deteriorates under droughts and heatwaves (68% of compiled cases), rainstorms and floods (51%) and under long-term climate change (56%). Also improvements or mixed responses are reported owing to counteracting mechanisms, for example, increased pollutant mobilization versus dilution during flood events. River water quality responses under multidecadal climate change are driven by hydrological alterations, rises in water and soil temperatures and interactions among hydroclimatic, land use and human drivers. These complex interactions synergistically influence the sources, transport and transformation of all water quality constituents. Future research must target tools, techniques and models that support the design of robust water quality management strategies, in a world that is facing more frequent and severe hydroclimatic extremes.
River water quality is generally deteriorating under droughts and heatwaves (68% of case studies), rainstorms and floods (51%) and multidecadal historical and future climate change (56%), although improvements and mixed responses are also reported.
Droughts and heatwaves result in lower dissolved oxygen and increased river temperature, algae, salinity and concentrations of pollutants (such as pharmaceuticals) from point sources owing to lower dilution. By contrast, low flow during these events leads to reduced pollutant transport from agricultural and urban surface runoff, contributing to lower concentrations.
Rainstorms and floods generally increase the mobilization of plastics, suspended solids, absorbed metals, nutrients and other pollutants from agricultural and urban runoff, although high flow can dilute concentrations for salinity and other dissolved pollutants. The sequence of extreme events (such as droughts followed by floods) also impacts the magnitude and drivers of river water quality responses.
Multidecadal climate change is causing water temperatures and algae to generally increase, partly causing a general decrease in dissolved oxygen concentrations. Nutrient and pharmaceutical concentrations are mostly increasing under climate change, whereas biochemical oxygen demand, salinity, suspended sediment, metals and microorganisms show a mixture of increasing and decreasing trends.
The main driving mechanisms for multidecadal water quality changes in response to climate change include hydrological alterations, rises in water and soil temperatures and interactions of hydroclimatic drivers with land use. These impacts are compounded with other human-induced drivers.
Our findings stress the need to improve understanding of the complex hydroclimatic–geographic–human driver feedbacks; water quality constituent fate, transport, interactions and thresholds; and to develop technologies and water quality frameworks that support the design of robust water quality management strategies under increasing hydroclimatic extremes.

Turbidity is an essential biogeochemical parameter for water quality management because it shapes the physical landscape and regulates ecological systems. It varies spatially and temporally across large water bodies, but monitoring based on point-source field observations remains a difficult task in developing countries due to the need for logistics and costs. In this study, we present a novel semi-analytical approach for estimating turbidity from remote sensing reflectance \(({R}_{{\text{rs}}})\) in moderate to highly turbid waters in the lower part of the Godavari River (i.e., locations near Rajahmundry). The proposed method includes two sub-algorithms—Normalized Difference Turbidity Index (NDTI) and semi-empirical single-band turbidity ( \({T}_{{\text{s}}}\) ) algorithm—to retrieve spectral reflectance information corresponding to the study locations for turbidity modeling. Sentinel-2 Multi-Spectral Imager data have been used to quantify the turbidity in the Google Earth Engine (GEE) platform. The correlation analysis was observed between spectral reflectance values and in situ turbidity data using cubic polynomial regression equations. The results indicated that the \({T}_{{\text{s}}}\) , which uses the only red-edge wavelength, identified turbidity as the most accurate across all locations (highest R 2 = 0.91, lowest RMSE = 0.003), followed by NDTI (highest R 2 = 0.85, lowest RMSE = 0.05), respectively. The remote sensing data application provides a better way to monitor turbidity at large spatio-temporal scales in attaining the water quality standards of the Godavari River.

Vrishabhavathi Watershed is a constituent of the Arkavathi River Basin, Bangalore Urban and Ramanagara District and covers an area of 360.62 Km2, representing seasonally dry tropical climate. In Vrishabhavathi catchment Vrishabhavathi River is the main source of surface water source which is tributary of River Arkavathy, which joins the Cauvery River at Mekedatu near sangama. Earlier this holy water was mainly used for agricultural purpose and drinking purpose. The Catchment lies in Bangalore urban and Bangalore rural area. The stream which flows in urban region receives a lot of waste water released from industrial and domestic areas. The water is highly polluted and generates lot of foul smell in the flow stretch in urban region. An attempt has been made to identify the potential sites for detention ponds along the Vrishabhavathi River which will be used to maintain the acceptable water quality for sewage Irrigation. For this analysis we need the Base map and thematic maps such as Drainage map, Land use /land cover map and Vrishabhavathi River geometry map. Remote sensing and GIS is useful tool to identify the suitable sites for detention ponds along the River. By assigning the weights to point feature in Vrishabhavathi River geometry map, then calculating suitability indices potential sites for detention ponds are identified .The water stored in the detention ponds are continuously treated with minimum cost and allowed to flow in the downstream for further oxidation. At suitable location water can be lifted up to suitable near water body and used for sewage irrigation.

West Bengal (88,752 km²) is the only Indian state that stretches from the Himalaya to the Bay of Bengal. It can be divided into nine physiographic provinces of which the Himalayas, the western plateaus, the northern and western alluvial fans and the Ganga delta are most important. The development of the river system of the state was largely governed by tectonic evolution of the eastern Himalaya and western edges of the Bengal basin. The characteristics of the rivers as well as a number of aspects of water resources of the state can be linked to its physiographic regions. The principal issues associated with water in West Bengal include river degeneration, channel shifting, flood, urban waterlogging, drought, pollution, groundwater depletion and inland navigation. The management of water is practised by river impoundment projects in various scales and by drainage schemes. It is estimated that the western and eastern parts of the state are most water stressed regions due to climatic and human factors, respectively. The solution to many of the water-related problems of West Bengal, progressive or cyclic, can be addressed by putting emphasis on participatory management besides government intervention.

Water planning decisions are only as good as our ability to explain historical trends and make reasonable predictions of future water availability. But predicting water availability can be a challenge in rapidly growing regions, where human modifications of land and waterscapes are changing the hydrologic system. Yet, many regions of the world lack the long-term hydrologic monitoring records needed to understand past changes and predict future trends. We investigated this “predictions under change” problem in the data-scarce Thippagondanahalli (TG Halli) catchment of the Arkavathy sub-basin in southern India. Inflows into TG Halli reservoir have declined sharply since the 1970s. The causes of the drying are poorly understood, resulting in misdirected or counter-productive management responses. Five plausible hypotheses that could explain the decline were tested using data from field surveys and secondary sources: (1) changes in rainfall amount, seasonality and intensity; (2) increases in temperature; (3) groundwater extraction; (4) expansion of eucalyptus plantations; and (5) fragmentation of the river channel. Our results suggest that groundwater pumping, expansion of eucalyptus plantations and, to a lesser extent, channel fragmentation are much more likely to have caused the decline in surface flows in the TG Halli catchment than changing climate. The multiple-hypothesis approach presents a systematic way to quantify the relative contributions of proximate anthropogenic and climate drivers to hydrological change. The approach not only makes a meaningful contribution to the policy debate but also helps prioritize and design future research. The approach is a first step to conducting use-inspired socio-hydrologic research in a watershed.

Background: Urbanization as a structural process of change is generally related to the concentration of large-scale and small scale industrial and commercial, financial and administrative set up in the cities (Newman, 2011). Accelerated urbanization and industrialization are two of the main processes responsible for increased pressure and deterioration of water resources. Naihati Municipality in Barrackpore Sub division is highly urbanized area and the population pressure is also very high which affects the quality and also quantity of ground water sources. The people of this municipality depend on the underground water sources for their daily domestic water use and also drinking purposes. Besides, due to the rapid growth of industrialization mainly, different small and medium scales industries the whole required water withdrawals from the underground water sources. This study reveals the affects of urban industrial expansion on water resources both the ground water and also the surface water sources. Materials and Methods: Naihati Municipality has a strong industrial background and a huge population pressure, to understand the present situation of water sources both the surface and ground water source so this study consist both the Primary survey (including GPS survey) and secondary data collections methods. Primary data were collected through household survey by interview (face to face) method and the secondary data was collected from different secondary sources like Barrackpore Subdivision Office, Naihati Municipality, District Census hand book and Census of India. All the collected data were tabulated and computed through MS ward 2007 and MS Excel for constructing different charts and diagrams by using various cartographic techniques. Maps are prepared through (QGIS, Arc GIS) open source software. Results: In the Naihati Municipality there are 31 no of wards with a density of population 18891 person/sq km (2011). Due to the urban growth and also industrial development a high water demand is noticed here. But the municipal water supply does not satisfy this high demand of water among the urban people and create a negative water balance. Besides, the only water source is from underground water so naturally the ground water levels decline day by day. This study represents the above scenario of Naihati Municipality and introduced some possible suggestions and recommendations. Conclusion: From the study it is identified that urbanization is highly related the industrialization and also modernization. A rapid growth of industrialization and increasing population are the two main features in this municipality along the bank of the river Hugly, for easy availability of water and transport.
