| water erosion | erosión hídrica |
| water erosion The breakdown of solid rock into smaller particles and its removal by water. As weathering, erosion is a natural geological process, but more rapid soil erosion results from poor land-use practices, leading to the loss of fertile topsoil and to the silting of dams, lakes, rivers and harbours. There are three classes of erosion by water. 1. Splash erosion occurs when raindrops strike bare soil, causing it to splash, as mud, to flow into spaces in the soil and to turn the upper layer of soil into a structureless, compacted mass that dries with a hard, largely impermeable crust. 2. Surface flow occurs when soil is removed with surface run-off during heavy rain. 3. Channelized flow occurs when a flowing mixture of water and soil cuts a channel, which is then deepened by further scouring. A minor erosion channel is called a rill, a larger channel a gully | erosión hídrica |

| water surface | nivel del mar |
| water-table | nivel hidrostático |
| water-table | capa freática |
| water table Water that occupies pores, cavities, cracks and other spaces in the crustal rocks. It includes water precipitated from the atmosphere which has percolated through the soil, water that has risen from deep magmatic sources liberated during igneous activity and fossil water retained in sedimentary rocks since their formation. The presence of groundwater is necessary for virtually all weathering processes to operate. Phreatic water is synonymous with groundwater and is the most important source of any water supply | capa freática |
| water table protection | protección de la capa freática |
| water table protection Water table is inherently susceptible to contamination from landuse activities. Remediation is very expensive and often impractical. Prevention of contamination is therefore critical in effective groundwater management | protección de la capa freática |
| water taste | sabor del agua |
| water taste Taste in water can be caused by foreign matter, such as organic compounds, inorganic salts or dissolved gases. These materials may come from domestic, agricultural or natural sources. Some substances found naturally in groundwater, while not necessarily harmful, may impart a disagreeable taste or undesirable property to the water. Magnesium sulphate, sodium sulphate, and sodium chloride are but a few of these. Acceptable waters should be free from any objectionable taste at point of use | sabor del agua |

| water utilisation | utilización de agua |
| water utilisation Three types of water use are distinguished: 1. withdrawal, where water is taken from a river, or surface or underground reservoir, and after use returned to a natural water body, e.g. water used for cooling in industrial processes. Such return flows are particularly important for downstream users in the case of water taken from rivers; 2. consumptive, which starts with withdrawal but in this case without any return, e.g. irrigation, steam escaping into the atmosphere, water contained in final products, i.e. it is no longer available directly for subsequent uses; 3. non-withdrawal, i.e. the in situ use of a water body for navigation (including the floating of logs by the lumber industry), fishing, recreation, effluent disposal and hydroelectric power generation | utilización de agua |
