Hydrology (from Greek: ὕδωρ, "hýdōr" meaning "water" and λόγος, "lógos" meaning "study") is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability.A practitioner of hydrology is called a hydrologist. catchment area definition: 1. the area of land from which water flows into a river, lake, or reservoir: 2. the area served by….

Runoff, in hydrology, quantity of water discharged in surface streams.Runoff includes not only the waters that travel over the land surface and through channels to reach a stream but also interflow, the water that infiltrates the soil surface and travels by means of gravity toward a stream channel (always above the main groundwater level) and eventually empties into the channel. Catchment Area synonyms. (a).
