The Changes in the Physico-chemical parameters of a waterbody-A Case Study of Brari Nambal Lagoon, Kashmir Valley

Abstract

The experimental investigation was conducted to evaluate the water quality of the Brari Nambal lagoon located in Srinagar city of Kashmir valley. To undertake this study, analysis of physicochemical parameters was carried out at three sampling sites during the winter season of 2022. These results were compared with the data of 2010, 2013, 2016, and 2019 for the same season to determine the changes that have occurred within this time frame. Comparative analysis of data revealed that TP, –PO4 -3, NH4-N, NO- 3N and TDS levels have been increased from 2010 to 2022. Further, the data related to physicochemical parameters was analyzed using Pearson’s correlation method. Water quality of the lagoon was also examined based on the water quality index. Based on current experimental analysis, it is evident that this lagoon is being impacted by increased human activities in its surrounding area, leading to increased urban intensification. This, in turn, affects the overall hydrochemistry of the lagoon. The flexibility to address these issues within the lagoon’s ecosystem can be maintained until external management strategies are implemented to strengthen its natural balance. Implementing specific remedial measures is crucial for the effective management of the lake and the preservation of its natural quality, provided they are executed correctly.
