| Abstract | The water bodies in India have been polluted due to escalating population, urbanization and economic activities resulting in severe deterioration of the water quality. In view of the continuously degrading quality of our water resources and its impact on human health, aquatic life and the environment, effective water quality assessment has become critical. The predominant techniques used in India for water quality assessment involve in situ measurements and/or the collection of water samples followed by laboratory analyses. These popular techniques however, are limited on temporal and spatial scales of the water quality trends. This paper highlights the limitations associated with the conventional water quality assessment method and discusses the recent advanced RS and GIS techniques as a promising perspective for effective water quality assessment. The paper concludes with suggestions on applications of RS and GIS in effective water quality assessment and in taking prompt and consistent water management decisions for the conservation of water resources in India. |
