Abstract:

Bank erosion is an inevitable vestige of past to evident fluvial dynamics in relation to its discharge and velocities and work-load in view of its load washed or unwashed. The central idea is best suited to study the case of River Mahananda alias Mahanadi within the Upper Mahananda River basin area having similar kind of attestation of facts. The present study needed extraction of satellite imageries of Landsat from USGS sites associated with its processing and ultimately to frame out the temporal scenes through NDVI technique to visualize if the forest cover is at all influenced by bank erosion or not or for specific scales whatever is the reality. The inference registered heavy scouring along the hugging banks with temporal avulsions and bed aggradation. The rates of change of foothill forest areas and variation of cultivable areas for a period of 30 years initiating from 1990 is addressed to study here.

Abstract:

This article identifies two main perspectives on flood control: the traditional and the modern hydrological. The objective here is to look at the contest between them from the point of view of the politics of knowledge. The traditional perspective views floods as a part of life and focuses on people’s wisdom or local knowledge of flood control. The hydrological approach, on the other hand, is mostly concerned with taming a river and views floods as a disaster that ought to be controlled and possibly eliminated. This perspective dominates the policy of the post-colonial state in India. There are five vantage points, such as historical context, state policy, political economy, collective action and epistemology, to understand the politics of knowledge around floods. In the first section, through history we discuss the transition from the colonial to post-colonial India on the issues of floods, dams and embankments. The second section of this article describes the flood policy and politics around it, from Patna Flood Conference (1937) to Disaster Management Act, 2005. In Political Economy section the article explores the link between land-holdings, tenancy and floods and also observes how agriculture has changed due to floods. The fourth section, Forms of Collective Action, explores the politics of collective action. Epistemology section presents the debate of lokvidyavs versus rajyavidya or living with floods versus hydrological knowledge.

Abstract:

Background: Endotracheal intubation is an essential resuscitative procedure in the emergency setting, to maintain a patent airway. In our day-to-day practice at a tertiary care centre calls for intubation remain in quite a demand. As we all know in the emergency setting we first advocate maintaining the so-called A (airway), B(breathing) and C(circulation) and this is where lies the importance of intubation. Objective: The study was done to assess the knowledge, competency, and exposure regarding emergency airway management among healthcare workers in this region of West Bengal which caters to patients from the Mahananda Basin, in particular, Malda. Methodology: A questionnaire-based cross-sectional study was conducted. The study tool was a standard questionnaire containing 14 questions, which was developed to assess the knowledge, exposure, and practice of the study group in a Tertiary Care Centre of West Bengal. Results: the questionnaire based analytical study revealed gross lack of knowledge among caregivers regarding management of airway during emergency situations. Inference: Basic knowledge in terms of theory seems to prevail among almost all the participants but they lack the congruity between knowledge and exposure, hence an interactive curriculum should be designed to train the target groups in order to avoid the catastrophe seen during emergency situations.

Abstract:

The Mahanadi River is an interstate (Chhattisgarh and Odisha) river in India that flows for 851 kilometers, 357 of which are in Chhattisgarh. It is the lifeline of Chhattisgarh and Odisha. The Mahanadi River Basin (MRB) in Chhattisgarh covers an area of 75,136 km2 . This paper provides a detailed database on water demand and use, LULC changes, biodiversity, pollution status, and man-made structures, such as dams/ reservoirs, built in the Mahanadi river basin in Chhattisgarh. The significance of this overview paper stems from the fact that it improves river management and water distribution for various sectors in Chhattisgarh. Furthermore, it aids in the mitigation and adaptation to climate change, as well as the achievement of sustainable development goals.

Abstract:

The Mahanadi river faces large-scale ecological disaster due to a variety of anthropogenic stresses. A prime factor is rapid industrialisation and coal-fired power generation plans that are being encouraged by the states of Odisha and Chhattisgarh. These are not only impacting the flow of the river’s waters and damaging the health of its basin but have also made the area susceptible to climate change. The industrial growth-based development has already polluted the Mahanadi to an irrecoverable extent. The over-allocation of water to industries has adversely effected the region’s irrigation and agriculture leading to a bitter contestation between industry and the farming community. As this comment emphasises, both state governments are taking advantage of the Mahanadi river for industrial use to maximise revenue generation but are at the same time are being insensitive to the adverse environmental and ecological consequences that such exploitation will surely lead to.

Abstract:

The potential impact of climate variability on the hydrological regime in the Mahanadi river basin is of great importance for sustainable water resources management. The impact of climate variability on streamflow is analyzed in this study. The impact of climate variability modes on extreme events of Mahanadi basin during June, July, and August (JJA), and September, October, and November (SON) seasons were analyzed, with daily streamflow data of four gauge stations for 34 years from 1980 to 2013 found to be associated with the sea surface temperature variations over Indo-Pacific oceans and Indian monsoon. Extreme events are identified based on their persistent flow for six days or more, where selection of the stations was based on the fact that there was no artificially regulated streamflow in any of the stations. Adequate scientific analysis was done to link the streamflow variability with the climate variability and very significant correlation was found with Indian Ocean Dipole (IOD), El Nino Southern Oscillation (ENSO), El Nino Modoki Index (EMI), and Indian monsoon. Agriculture covers major portion of the basin; hence, the streamflow is very much essential for agriculture as well as population depending on it. Any disturbances in the general flow of the river has subjected an adverse impact on the inhabitants’ livelihood. While analyzing the correlation values, it was found that all stations displayed a significant positive correlation with Indian Monsoon. The respective correlation values were 0.53, 0.38, 0.44, and 0.38 for Andhiyarkore, Baronda, Rajim, and Kesinga during JJA season. Again in the case of stepwise regression analysis, Monsoon Index for the June, July, and August (MI-JJA) season (0.537 for Andhiyarkore) plays significant role in determining streamflow of Mahanadi basin during the JJA season and Monsoon Index for July, August, and September (MI-JAS) season (0.410 for Baronda) has a strong effect in affecting streamflow of Mahanadi during the SON season. Flood frequency analysis with Weibull’s plotting position method indicates future floods in the Mahanadi river basin in JJA season.

Abstract:

The processes of weathering and erosion are the most important natural events that reshape the surface of the earth and regulate geochemical cycling of elements. The study of processes involved in rock weathering, sediment formation and subsequent transfer of weathered materials by the river to the ocean is essential for understanding different earth surface processes. The transport of sediments by rivers to the oceans represents an important link between the terrestrial and marine ecosystem. Chemical weathering of rocks releases soluble products and produce solid residues, which control the land-ocean-atmospheric fluxes and earth’s climate. The geochemistry of river sediments gives information about the provenance characteristics and characteristics of weathering and erosion in a basin. Therefore, this thesis aims to study the spatio-temporal variation of the sediment discharge and erosion rate, geochemistry of water and sediments of the Mahanadi river basin, one of the biggest rivers in India to understand the weathering characteristics of the basin. The trend analysis study is conducted in the time series data (1981-2010) of water flux sediment discharge and rainfall (1990-2010) of the Mahanadi river to study the sediment load variation. The trend test result represents that the sediment load delivered from the Mahanadi river to the global ocean has decreased sharply at the rate of 0.42×106 tons/year between 1981 and 2010. Water discharge and rainfall in the basin show no significant decreasing trend except at only one tributary. The decline in sediment discharge from the basin to the Bay of Bengal is mainly due to the increase in the number of dams, which shows the increase from 70 to 253 during the period of 1980 to 2010. Over the past 30 years, the Mahanadi river discharges about 48.01±20 km3 of water and 14.52±12.7×106 tons of sediment annually to the Bay of Bengal whereas the mean erosional rate is 238±116 tons/km2/year. Based on the current data (2001–2010), sediment flux and water discharge to the ocean are 11.02±5×106 tons/year and 50.91±16 km3/year respectively; and ranking Mahanadi river second in terms of water discharge and sediment flux to the ocean among the peninsular rivers in India. The sediment load in the basin is mostly influenced by the variation in water discharge and relief. The results of hydrogeochemical study of the Mahanadi river basin reveal that the dissolved loads in the basin are dominantly controlled by rock weathering particularly chemical weathering of silicates and carbonates. The TDS in the basin is higher than the global average. The estimated chemical weathering rates based on the forward model are 44.94 tons/km2/year in monsoon and 2.45 tons/km2/year in pre-monsoon with annual average chemical weathering rate of 23.69 tons/km2/year. The contributions of silicate weathering rates in the basin are 32.15 and 1.55 tons/km2/year during monsoon and pre-monsoon period respectively. The estimated CO2 consumption rate associated with chemical weathering in the basin is 13.3×105 mol/km/year during monsoon and 0.66×105 mol/km/year during pre-monsoon period with an average annual rate of 6.91×105 mol/km/year which is higher than the global average and most Indian rivers. The net rate of CO2 consumption by silicate weathering is estimated to be approximately 4.78×105 mol/km/year. It is observed that the runoff and lithology are the major factors influencing chemical weathering in the basin. The geochemistry of sediment shows that they are mainly derived from felsic source rocks with a minor contribution from mafic and carbonate rocks. This is also evidenced from the ratio of Al2O3/TiO2, higher content of K2O and Rb along with the abundance of quartz, feldspar and variable quantity of dolomite and calcite in the sediments. Higher values of (La/Lu)N and LREE/HREE ratios suggest the presence of acidic source rock in the basin. The majority of sediments are chemically similar to arkose and litharenite sandstone. The values of the chemical index of alteration (CIA), index of compositional variability (ICV) and the ratio of Rb/Sr indicate most of the sediments are compositionally immature and undergone weak weathering. Positive Ce anomaly, as well as the ratios of Ni/Co and V/Cr, suggests oxidising environments of deposition. The sediments are deposited on a passive continental marginal setting with semi-arid to semi-humid climatic condition.

Abstract:

The increasing rate of global surface temperature is going to have significant impact on local hydrological regimes and thus on water resources, this leads to the assessment of water resources potential resulting from the climate change impacts. Main parameters that are closely related to the climate change are temperature, precipitation and runoff. Therefore, there is a growing need for an integrated analysis that can quantify the impacts of climate change on various aspects of water resources. The present work intends to determine climate change impact on the hydrological processes in the Mahanadi River Basin through:(1) Statistical analysis of historical and future climate trends, (2) use of General Circulation Models (GCM) for simulating the response of climate variables globally, accounting for the effects of greenhouse gases in the atmosphere, (3) use of statistical downscaling technique to model the hydrology variables (e.g., precipitation) at a smaller scale based on large scale GCM outputs, (4) use of hydrological modelling for assessment of global climate change impacts. Statistical trend analysis has been done using Mann Kendall Test and Sen’s Slope Estimator to find out the magnitude of the trend for the historical and future records. Statistical downscaling model has been used to predict the future precipitation and temperature time series from the year 2011 to 2099 by using HadCM3 coupled model. Artificial Neural Network (ANN) and Multiple Linear Regression analysis has been used to predict the future runoff from the precipitation and temperature.

Abstract:

Environmental flow (EF) is referred as the amount of water regarded as sufficient for shielding or maintaining the construction & function of an ecosystem and its dependent species. River systems attain zero flow due to construction of water Retaining Structures, Hydropower generating Structures, construction of bridges etc. which possess a tremendous and huge threat to the environment, ecology & aquatic life of the river systems. Thus, Environment Flow assessment is done in order to analyse and infer the natural flow regime of the river which is required to be in existence for the sustainability of the ecosystem. In the present work, we are going to assess the Environmental Flow of the Mahanadi River Basin based on the Tennant method, RVA (Range of Variability Analysis), Flow Duration curve (FDC) & Flow Indices method (i.e 7Q10, 7Q2 etc), FDC shift and Spatial Interpolation method (applied on FDC). Tennant (or Montana) method utilizes a percentage of the average annual Flow (MAF) for two separate six month periods to classify the various circumstances of flow, whereas RVA uses IHA (Indicators of hydrologic Alterations) applications, to determine low flow, high flow, maximum high flow etc. Flow Indices (Q95, Q90 etc.) and the 7Q10, 7Q2 methods are computed with which the different low discharges are determined for the eight stations covering the whole Mahanadi river basin. Environmental Management classes are categorised here such that by shifting the FDC for each and every station, the flow can be analysed from the extreme modified (very poor) flow to the high flow. Spatial Interpolation method using the Flow-Duration curve computes the discharge of the destination station using the value of the source station.

Abstract:

Water is life. But if the quality of water is poor, it may become poison. Scientists and researchers have opined that the quality of water available to a society is an important factor in determining the quality of life as a whole in the society. Urban, industrial and agricultural activities, increasing consumption of water resources as well as natural processes such as change in precipitation inputs, erosion etc. damage surface water quality. Therefore, assessment of surface water quality is required as it directly affects public health. In our study, we have selected Mahanadi river basin which lies predominantly in Chhatisgarh and Odisha. During the last few decades, many water quality monitoring programs are used for reliable estimates of the water quality in view of the temporal and spatial variations in hydrochemistry of river in this region. Eight gauging stations were selected in total for collecting the data for various water quality parameters viz.,pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Electrical Conductivity, Nitrogen as nitrate (NitrateN), Total Coli-form Bacteria(TC), Fecal Coli-form Bacteria(FC), Chemical Oxygen Demand (COD), Nitrogen as ammonia (NH4-N), Total Alkali (TA) as CaCO3, Total Hardness (TH) as CaCO3. Analysis of water quality was done by PCA and PFA techniques. The spatial analysis was done using GIS interpolation technique of Inverse Distance Weighted method. Then a physical water quality model was created using SWAT. The coefficient of determination for the calibration period (1991-2000) was found to be 0.75 for the discharge at Tikarapara (selected outlet) and for validation period (2001-2010) R2 came to be 0.66 using SUFI2 which showed the model predicts the flow satisfactorily. For the water quality BOD and DO (important parameters as found by PFA) were selected for the calibration and validation. The R2 came out to be 0.863 and 0.726 for BOD and DO respectively in calibration period. And for validation period the values were 0.785 and 0.688 respectively.

Abstract:

Rivers are dynamic geologic agents on earth and act as the main pathways for transport of continental materials to the ocean. Estimation and forecasting of suspended sediment yield (SSY) are essential towards understanding the mass balance between the ocean and land. The volume of SSY transported in a river provides important information about its morphodynamics, the hydrology of its drainage basin, and the erosion and sediment delivery processes operating within that basin. Estimation and forecasting of SSY is always a key factor during the evaluation of reservoir project, protection of fish and wildlife habitats, understanding of flood capacity, hydroelectric equipment longevity, planning and management of any river system. The SSY depends on number of variables and their inter-relationships which are highly nonlinear and complex in nature. Direct measurement of SSY is difficult and needs sufficient time and money. Additionally, it is difficult to estimation and forecasting of the SSY by using traditional mathematical models because they are incapable to handle the complex non-linearity and non-stationarity process. Thus, the aim of this study is to develop hybrid simple genetic algorithm based artificial neural network (GA-ANN) and genetic algorithm based multi objective optimization with artificial neural network (GA-MOO-ANN) models to estimate and forecast the SSY at eleven locations in the Mahanadi river basin, which is one of the largest rivers in India. All parameters associated with the models are optimized simultaneously using simple genetic algorithm and multi-objective genetic algorithm for estimation and forecasting of the SSY. Temporal information of monthly rainfall, temperature, water discharge, and suspended sediment yield during 1990-2010 along with rock type, relief and catchment area are used at all eleven gauging stations in Mahanadi river for the development of models. It is observed that water discharge and SSY show wide fluctuations whereas temperature and rainfall do not show much variation among different gauge stations in the basin. The performances of GA-MOO-ANN and GA-ANN models were compared to traditional artificial neural network (ANN), multiple linear regression (MLR), auto regressive (AR), multi variate auto regressive (MAR) and sediment rating curve (SRC) method for evaluating the estimation and forecasting capability of models on testing data set. The results suggested that the hybrid GA-MOO-ANN and GA-ANN models exhibited satisfactory performance and provided better results than the traditional ANN, MLR, AR and MAR models. The models are unable to estimate and forecast the SSY at gauge stations having very small catchment areas whereas performing satisfactory on locations having moderate to large catchment area. The models provide the best result at Tikarapara, the gauge station location in the extreme downstream, having the largest catchment area. If measurements of suspended sediment are not available in any river then the modelling approach can be potentially used for the estimation and forecasting of SSY at gauge or ungagged locations.

Abstract:

In flood frequency analysis, the modeling based on Annual Maximum Flood (AMF) series remains the most popular approach. An alternative approach based on the “partial duration series (PDS) or peaks over threshold (POT)” has been considered in recent years, which captures more information about extreme events by fixing appropriate threshold values. The PDS approach has lot of advantages, (i) it consist more peak events by selecting the appropriate threshold hence to capture more information regarding the flood phenomena. (ii) it analyses both, the time of arrival and the magnitude of peaks, (iii) it provides extra flexibility in the demonstration of floods and a complete explanation of the flood generating process. However, the PDS approach remains underused and unpopular due to the nonexistence of general framework regarding different approaches.The first objective of the present research work is to develop a framework in the above question on selection of an appropriate threshold value using different concepts and, to verify the independency and stationarity criteria of the extreme events for the modeling of the PDS in the Mahanadi river system, India. For the analysis, daily discharge data from 22 stations with record length varying between 10 and 41 years have been used with the assumption that the whole basin is homogeneous in nature. The results confirmed that the Generalized Pareto (GP) best described the PDS in the study area and also, show that the best PDS/GP performance is found in almost all the value of λ (2, 2.5 and 3). In the second phase, the analysis is done to carry out the regional flood frequency analysis in the Mahanadi basin and to apply the developed model to the respective homogeneous region. Regionalization is the best viable way of improving flood quantile estimation. In the regional flood frequency analysis, selection of basin characteristics, morphology, land use and hydrology have significant role in finding the homogeneous regions. In this work the Mahanadi basin is divided into homogeneous regions by using fifteen effective variables initially. However, it has been observed that the whole basin is not hydro meteorologically homogeneous. Therefore, Factor analysis has been introduced in finding suitable number of variables, and nine variables are found suitable for analysis. Hierarchical (HC) and K-Means Clustering (KM) techniques are used for finding out the possible number of clusters. Here, again the Generalized Pareto (GP) distribution best described the PDS in the study area. To test the homogeneity and to identify the best-fit frequency distribution, regional L-moment algorithm is used. A unique regional flood frequency curve is developed which can estimate the flood quantiles in ungauged catchments and an index flood is also specified concerning the catchment characteristics by using the multiple linear regression approach.

Abstract:

Studies of geologic and geophysical data from the offshore of India have revealed two geologically distinct areas with inferred gas hydrate occurrences: the passive continental margins of the Indian Peninsula and along the Andaman convergent margin. The Indian National Gas Hydrate Program (NGHP) Expedition 01 was designed to study the occurrence of gas hydrate off the Indian Peninsula and along the Andaman convergent margin with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings. NGHP Expedition 01 established the presence of gas hydrates in Krishna- Godavari, Mahanadi and Andaman basins. The expedition discovered one of the richest gas hydrate accumulations yet documented (Site 10 in the Krishna-Godavari Basin), documented the thickest and deepest gas hydrate stability zone yet known (Site 17 in Andaman Sea), and established the existence of a fully-developed gas hydrate system in the Mahanadi Basin (Site 19).

Abstract:

Strontium (Sr) is an alkaline earth element that has four naturally occurring stable isotopes, 84Sr, 86Sr, 87Sr and 88Sr. During measurements of the radiogenic Sr isotope ratio (87Sr/86Sr), which is a widely used tracer in Earth sciences, the instrumental mass dependent fractionation is corrected by assuming the 88Sr/86Sr ratio as 8.375209. However, with the recent advancements in mass spectrometry, it is now possible to resolve variations in the 88Sr/86Sr ratio (expressed as δ88/86Sr) in natural samples. In this study, a measurement protocol for stable Sr isotope ratio measurements was developed using a double spike thermal ionization mass spectrometry (DS-TIMS) technique and δ88/86Sr variability in depth-bound seawater, groundwater, and large rivers are investigated. The analytical technique for high precision TIMS measurements of δ88/86Sr was developed using a new Sr double spike (87Sr-84Sr); the single spikes used to prepare this double spike were less pure compared to the spikes reported in literature and hence the DS of this study is less expensive and differs in isotopic composition from DS used in previous studies. The robustness of the method was validated by measurements of multiple standards of different matrices (carbonate, silicate, seawater, and pure Sr) and the long-term external reproducibility of δ88/86Sr was less than ± 0.035 ‰ (2SD) which is comparable to, if not better than previous studies. The δ88/86Sr values are not affected by the nature of the loading filament (tantalum versus zone refined rhenium) or amount of Sr loaded on the filament; further, the δ88/86Sr values are invariant over a wide range of spike/sample ratios, consistent with modelling calculations for error propagations. The δ88/86Sr values, relative to the NIST SRM987 standard, are reported for an Alfa Aesar ICPMS Sr standard (0.101 ± 0.033 ‰), NASS-6 seawater (0.387 ± 0.034 ‰), JCp-1 coral carbonate (0.196 ± 0.006 ‰), JCt-1 clam shell (0.252 ± 0.004 ‰), BCR-2 basalt (0.264 ± 0.003 ‰), and NIST SRM987 (0 ± 0.023 ‰). The Bay of Bengal, which has crucial control on marine Sr budget, receives large influx of continental Sr through the Himalayan rivers in form of surface flow with additional contribution from groundwater discharge. The present study reports restricted variability in the δ88/86Sr values (0.373-0.411 ‰) of seawater samples collected from multiple depths (0-1500 m) in the Bay of Bengal with an average δ88/86Sr = 0.388 ± 0.025 ‰ (2SD), which overlaps with previous estimates of global seawater. The chemistry of coastal seawater can be significantly influenced by groundwater and interactions between Bengal Basin groundwater and the adjacent Bay of Bengal seawater are well documented. This thesis presents δ88/86Sr values, 87Sr/86Sr, as well as stable Ca isotope (δ44/40Ca) data for a set of groundwater samples collected from multiple depths (14-333 mbgl) from coastal aquifers in and around the Sundarbans delta, India. Significant variabilities were observed in 87Sr/86Sr, salinity, and cation concentrations across depths which indicate seawater incursion at shallower depths (14-42 mbgl) while deep aquifer samples (~333 mbgl) retained freshwater signature. A substantial variability in δ88/86Sr values (~0.542 ‰) was observed in these groundwater samples with shallow aquifer samples showing high δ88/86Sr (up to 0.666 ‰), which is higher than modern seawater (~0.388 ‰). These variations along with modelling results suggest appreciable amounts of precipitation of secondary carbonates in the saline groundwaters along with indications of seawater-freshwater mixing. The δ44/40Ca values of the same samples show similar trends as the δ88/86Sr values and are consistent with removal of solute Ca as aragonites or calcites (up to 45%). Rivers are major transport pathways of weathering-derived continental Sr to the oceans and play a major role in modulating the overall Sr budget among modern reservoirs. The δ88/86Sr values in seasonally and spatially resolved river water samples from the lower Ganges (Hooghly River) varied from -0.167 to 0.418 ‰ while those in seasonally distributed river water samples from the Brahmaputra, collected from Guwahati and Jorhat, range between 0.136-0.304 ‰. Spatially and seasonally resolved river water from the Mahanadi Basin display δ88/86Sr values between 0.263-0.638 ‰; few samples from coastal regions overlapped with Bay of Bengal δ88/86Sr values underscoring seawater intrusion. The Mahanadi Basin groundwater samples display δ88/86Sr values between 0.276-0.423 ‰, which overlap with compositions of the Mahanadi River water, consistent with riverwater-groundwater interactions. Seasonally resolved river water samples from the Godavari River, collected from Rajahmundry, showed δ88/86Sr variability between 0.174-0.640 ‰. Overall, the significant variability in δ88/86Sr values of these large rivers broadly overlap with global river water data and reflect varying sources, congruent versus incongruent chemical weathering, with implications for role of water mass mixing and secondary minerals, such as carbonates and clays in river waters.

Abstract:

Surface water is an important source for drinking water supply in Mahanadi Basin, Odisha. The research was done to evaluate the water quality, that serves as the source of domestic water supply to many cities. Samples of water were taken from nineteen important sampling areas for a period of 2010-2023 and twenty water quality parameters were examined to determine the WQI, followed by Multi-Criteria Decision-Making (MCDM) evaluation. Employing the Weighted Arithmetic (WA) Water Quality Index (WQI) and Stepwise Weight Assessment Ratio Analysis (SWARA) WQI, this study finds areas where cumulative variables, such as sewage discharge, a falling water table, dilution, and surface runoff, that tends to cause water quality variations in a water body, over a given monitoring period, have had the greatest impact. The WA WQI and SWARA WQI in the study area ranges from 23.78 to 96.09 and 14.6 to 1065.2, respectively. Also, the river water ranged from excellent to very poor, encompassing excellent for approximately 15.8%, good for 68.4%, poor for 10.5% and very poor for 5.3% in case of WA WQI. While the general water quality, as per SWARA-WQI, it varied from excellent to extremely poor, comprising 84.21% excellent, 10.53% poor and 5.26% for extremely poor category. The overall WQI in the study area indicates that the surface water is safe and potable except few localized pockets in SP-(8), (9) and (19) blocks. The cause could be attributed to anthropogenic sources such as domestic sewage and agricultural runoff altered a few parameters– e.g., TKN and TC. Based on geostatistical results, Gaussian model produce a more accurate assessment as per nugget/sill ratio, ASE and RMSE. To delineate the feasible regions for drinking practices, MCDM models such as Compromise Programming (CP), Ordered Weighted Averaging (OWA), and Combined Compromise Solution (CoCoSo), were adopted. Finally, the results demonstrated that WQI generated using both indexing strategies matched the outcomes of MCDM models. To sum up, it is advantageous and gives a clear image of water quality to combine physicochemical properties, WQIs, MCDM, and GIS technologies to evaluate surface water suitability for drinking and their controlling variables.
