| aquaculture | Farming of plants and animals that live in water, such as fish, shellfish, and algae. |
| aqueduct | A pipe, conduit, or channel designed fopr transport of water from a remote source, usually by gravity. |
| bedrock | A solid rock beneath the soil and superficial rock. A general term for silod rock that lies beneath soil, loose sediments, or other unconsolidated material. |
| commercial water use | Water used for motels, hotels, restaurants, other commercial buildings and institutions. Water for commercial uses comes both from public-supplied sources, such as a country water department, and self-supplied sources, such as local wells. |
| condensation | The process of water vapor in the air turning into liquid water. Water drops on the outside of a cold glass of water are condensed water. Condensation is the opposite process of evaporation. |
| evaporation | The process of liquid water becoming water vapor, including vaporization from water surfaces, land surfaces, and snow fields, but not from leaf surfaces. |
| transpiration | Process by which water that is absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface, such as leaf pores.frace |
| desalinization | The removal of salts from saline water to provide freshwater. This method is becoming a more popular way of providing freshwater to populations. |
| discharge | The volume of water that passes a given location within a given period of time. Usually expressed in cubic feet per second. |
| domestic water use | Water used for household purposes, such as drinking, washing clothes, dishes and dogs, flushing toilets, and watering lawns and gardens. |
| erosion | The process un which a material is worn away by a stream of liquid (water) or air, often due to the pressure of the abrasive particles in the stream. |
| flood | An overflow of water onto lands that are used or usable by man and not normally covered by water. Floods have essentially two characteristics: The inundation of land is temporary; and the land is adjacent to and inundated by overflow from a river, stream |
| glacier | A huge mass of ice, formed on land by the compaction of snow, that moves very slowly downslope or outward due to its own weight. |
| ground water (1) | Water that flows or seeps downward and saturates soil or rock, supplying springs and wells. The upper surface of the saturate zone is called the water table. |
| ground water (2) | Water stored underground in rock crevices and in the pores of geologic materials that make up the Earth's crust. |
| impermeable layer | A layer of solid material, such as rock or clay, which does not allow water to pass through. |
| infiltration | Flow of water from the land surface into the subsurface. |
| irrigation | The controlled application of water for agricultural purposes through manmade systems to supply water requirements not satisfied by rainfall. |
| levee | A natural or manmade earthen barrier along the edge of a stream, lake or river. Land alongside rivers can be protected from flooding by levees. |
| potable water | water of a quality suitable for drinking. |
| water cycle | The circuit of water movement from the oceans to the atmosphere and to the Earth and return to the atmosphere through various stages or processes such as precipitation, interception, runoff, infiltration, percolation, storage, evaporation, and transportat |
