Natural waters refer to bodies of water that are found in the environment and are not artificially created or altered by humans. This includes rivers, lakes, streams, ponds, wetlands, and oceans. Natural waters play a vital role in the ecosystem, providing habitats for a variety of plant and animal species, supporting biodiversity, and serving as sources of drinking water and irrigation for human populations. Research in the area of natural waters typically focuses on studying the quality, quantity, and dynamics of these bodies of water, as well as the impact of human activities such as pollution, climate change, and land use on their health and sustainability. This research often involves monitoring water quality parameters, studying aquatic ecosystems and biodiversity, investigating the effects of pollutants and contaminants on water bodies, and developing strategies for conservation and management of natural waters. By understanding the complexities of natural water systems and their interactions with the environment, researchers can work towards protecting and preserving these valuable resources for future generations.
