Estuaries receive the anthropogenic pollutants of their watershed area. Dhamra estuary, on the east coast of India, is such an estuary that receives a huge amount of pollutants, and it will eventually pose a threat to the ecological sensitive areas in its vicinity. Therefore, a study was carried out on physico-chemical parameters and chlorophyll-a to delineate the sources of variation during pre-monsoon and post-monsoon seasons. Surface water sampling was carried out from 12 stations in the estuarine and coastal area. Factor analysis and cluster analysis were applied to seasonal data to understand the sources of variation. From the study, it was observed that the chemical parameters are severely affected by anthropogenic influences such as sediment dredging, aquaculture effluent, and waste from industry and sewage from upstream. In the long run, this will affect the nearby nesting ground of vulnerable Olive Ridley turtles, high bio-diverse mangrove forests, and saltwater crocodile habitat.
河口接收其流域范围内的人为污染物。印度东海岸的达摩拉河口就是这样一个河口，它接收了大量的污染物，最终将对附近的生态敏感地区构成威胁。因此，在季风前和季风后季节进行了物理化学参数和叶绿素-a 的研究，以描绘变异的来源。从河口和沿海地区的 12 个站点进行了地表水采样。因子分析和聚类分析应用于季节性数据，以了解变异的来源。从研究中可以看出，化学参数受到人类活动的严重影响，如泥沙疏浚、水产养殖废水、工业废物和上游污水。从长远来看，这将影响到附近脆弱的橄榄海龟筑巢地、生物多样性极高的红树林和咸水鳄栖息地。
