Hydrology is the scientific study of water in the environment, focusing on its distribution, movement, and properties. It encompasses various processes such as precipitation, evaporation, and runoff, which are essential for understanding the water cycle and managing water resources effectively. Hydrologists analyze how water interacts with the atmosphere, land, and living organisms, contributing to sustainable practices in agriculture, urban planning, and environmental conservation. The field of hydrology plays a crucial role in addressing challenges like flooding, drought, and water quality. By studying rivers, lakes, and aquifers, hydrologists provide valuable insights that help communities adapt to changing climate conditions and ensure a reliable supply of clean water for future generations.
