The strength of the water cycle and its changes over time are of considerable interest, especially as the climate changes. [26] The hydrological cycle is a system whereby the evaporation of moisture in one place leads to precipitation (rain or snow) in another place. For example, evaporation always exceeds precipitation over the oceans.
The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
Hydrometry – the measurement of the different components of the hydrologic cycle; Chemical hydrology – the study of the chemical characteristics of water; Ecohydrology – the study of interactions between organisms and the hydrologic cycle; Hydrogeology – the study of the presence and movement of water in aquifers

Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and ...
The Coordinated Energy and Water Cycle Observations Project (CEOP) the 'Hydrology Project' is a major instrument in GEWEX. [5] This panel includes geographic study areas such as the Climate Prediction Program for the Americas operated by NOAA, [6] but also examines several types of climate zones (e.g. high altitude and semi-arid). [5]
Conceptual model describing the mechanisms of water flow attenuation within a beaver wetland with an unconfined floodplain. Ecohydrology (from Greek οἶκος, oikos, "house(hold)"; ὕδωρ, hydōr, "water"; and -λογία, -logia) is an interdisciplinary scientific field studying the interactions between water and ecological systems.
Water cycle management is a multidisciplinary approach relating to all planning, developmental, operational and tactical decisions to influence the water cycle. Most importantly water cycle management is used to ensure availability of clean water for designated use, and to ensure safe release of treated water back to nature.
