Hydrological Assessment and Water Quality Analysis of the Godavari River in Nashik City (Maharashtra)

Abstract: The Godavari River is often called the lifeline of Nashik; it is rich in hydrological, ecological, and cultural value. This research paper would discuss the hydrological features and water quality of the Godavari River in Nashik, as a city is deeply interlinked with the heritage and utility of the river. The paper studies the seasonality variations in flow pattern and critical water quality parameters such as pH, DO, BOD, and pollutant level. Among the causes, urbanization, industrialization, and anthropogenic pressures are cited to be the key factors degrading the river's health. This study is based on a comprehensive methodological framework that includes field measurements, laboratory analysis, and historical data to assess hydrological dynamics and water quality indices. Results show significant seasonal fluctuations, with monsoon periods diluting pollutants and non-monsoon seasons exacerbating contamination. The analysis identifies critical pollution hotspots, such as industrial zones and urban discharge points, where pollutant concentrations often exceed permissible limits. Elevated levels of heavy metals, including lead and cadmium, are particularly alarming, posing risks to aquatic ecosystems and human health. Its socio-economic features also make a strong argument for taking action. For irrigational purposes, agricultural populations can no longer afford poor-quality water with decreased efficiency in water conveyance and reduced agricultural produce. A large number of such river-users live in areas where health diseases are water-borne from untreated river water intake, and cultural and religious sensitivities are affected through polluting the sanctity of the river at places such as Kumbh Mela. Data visualization is very important in this study, and graphs and tables illustrate key trends and correlations. Seasonal flow data and pollutant levels are presented with hydrological assessments, thus providing a clear picture of the challenges that the Godavari River faces. The findings therefore point to the need for implementing sustainable water management practices, pollution control measures, and community engagement strategies. This study provides policy, research, and stakeholder guidance on how to revive and conserve the Godavari River. It promotes holistic river basin management practices that are supported by regulatory enforcement, technological innovation, and public participation. This will address the root causes of pollution and foster a culture of conservation, thereby conserving the Godavari River for future generations and preserving its ecological, economic, and cultural values.
