The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in having oceans of liquid water on its surface. [ 2] Liquid water, which is necessary for all known forms of life, continues to exist on the surface of ...
Cadillac Desert (1986) is an American history book by Marc Reisner about land development and water policy in the western United States.Subtitled The American West and Its Disappearing Water, it explores the history of the federal agencies, Bureau of Reclamation and U.S. Army Corps of Engineers, and their struggles to remake the American West in ways to satisfy national settlement goals.

Human-made surface water is water that can be continued by infrastructures that humans have assembled. This would be dammed artificial lakes, canals and artificial ponds (e.g. garden ponds) or swamps. [ 3 ] The surface water held by dams can be used for renewable energy in the form of hydropower. Hydropower is the forcing of surface water ...
Water balance in a basin. A general water balance equation is: [ 5] P = Q + ET + ΔS. where. P is precipitation. Q is streamflow. ET is evapotranspiration. ΔS is the change in storage (in soil or the bedrock / groundwater) This equation uses the principles of conservation of mass in a closed system, whereby any water entering a system (via ...
