Hydrologists study water. They focus on various aspects related to water such as its distribution, movement, quality, and quantity in the environment. Hydrologists analyze how water interacts with the atmosphere, soil, rivers, lakes, and groundwater systems. They also investigate the impact of human activities on water resources and work towards ensuring water sustainability for the present and future generations. In summary, hydrologists play a crucial role in understanding, managing, and protecting water resources for various purposes including drinking water supply, agriculture, industry, and ecosystems.
