pertaining to the science that encompasses the occurrence, distribution, movement and properties of the waters of the earth and their relationship with the environment within each phase of the hydrologic cycle The hydrologic cycle is a continuous process by which water is purified by evaporation and transported from the earth's surface (including the oceans) to the atmosphere and back to the land and oceans All of the physical, chemical and biological processes involving water as it travels its various paths in the atmosphere, over and beneath the earth's surface and through growing plants, are of interest to those who study the hydrologic cycle
{s} of or pertaining to hydrology, of the study of the properties and distribution of water on the earth in the atmosphere; of or pertaining to the properties and distribution of water on the earth and in the atmosphere
a science dealing with the properties, distribution, and circulation of water on the surface of the land, in the soil and underlying rocks and in the atmosphere
refers to water, and is often used to refer to the natural geographic characteristics affecting the overland flow of water, as in hydrologic characteristics
Representation of the flow of water in various states through the terrestrial and atmospheric environments Storage points (stages) involve groundwater and surface water, ice-caps, oceans, and the atmosphere
Cycle that involves the continuous circulation of water in the Earth-atmosphere system. Water is transferred from the oceans through the atmosphere to the continents and back to the oceans by means of evaporation, transpiration, precipitation, interception, infiltration, subterranean percolation, overland flow, runoff, and other complex processes. Although the total amount of water within the cycle remains essentially constant, its distribution among the various processes is continually changing
