| Terms for subject Environment (21507 entries) |
| hydrogen (A flammable colourless gas that is the lightest and most abundant element in the universe. It occurs mainly in water and in most organic compounds and is used in the production of ammonia and other chemicals, in the hydrogenation of fats and oils, and in welding) | hidrógeno | |
| hydrogen cloud | nube de hidrógeno | |
| hydrogen detector | detector de hidrógeno | |
| hydrogen detector | muestreador de hidrógeno | |
| hydrogen sulphide (Flammable, poisonous gas with characteristic odour of rotten eggs, perceptible in air in a dilution of 0.002 mg/l. It is used as a reagent in chemical analysis; extremely hazardous; collapse, coma and death from respiratory failure may come within a few seconds after one or two inspirations; low concentrations produce irritation of conjunctiva and mucous membranes. Headache, dizziness, nausea, lassitude may appear after exposure, H2S) | acido sulfhídrico | |
| hydrogen sulphide | acido sulfhídrico | |
| hydrogeochemistry | hidrogeoquímica | |
| hydrogeological risk | riesgo hidrogeológico | |
| hydrogeology (The science dealing with the occurrence of surface and ground water, its utilization, and its functions in modifying the earth, primarily by erosion and deposition) | hidrogeología | |
| hydrographic basin (1. The drainage basin of a stream. 2. An area occupied by a lake and its drainage basin) | cuenca hidrográfica | |
| hydrographic basin | cuenca hidrográfica | |
| hydrographic network (The configuration or arrangement in plan view of the natural stream courses in an area. It is related to local geologic and geomorphologic features and history. Synonym: drainage pattern) | red hidrográfica | |
| hydrographic network | red hidrográfica | |
| hydrography (Science which deals with the measurement and description of the physical features of the oceans, lakes, rivers, and their adjoining coastal areas, with particular reference to their control and utilization) | hidrografía | |
| hydrologic balance (An accounting of the inflow to, outflow from, and storage in a hydrologic unit such as a drainage basin, aquifer, soil zone, lake or reservoir; the relationship between evaporation, precipitation, runoff, and the change in water storage) | equilibrio hidrológico | |
| hydrologic balance | equilibrio hidrológico | |
| hydrologic cycle (The movement of water between the oceans, ground surface and atmosphere by evaporation, precipitation and the activity of living organisms, as one of the mayor biogeochemical cycles. Each day water evaporates from the oceans and is carried in the air from the sea over the land, which receives it as precipitation, and finally returns from the land to the sea through rivers, thus completing the cycle) | ciclo hidrológico | |
| hydrologic disaster (Violent, sudden and destructive change either in the quality of the earth's water or in the distribution or movement of water on land, below the surface or in the atmosphere) | desastres hidrológicos | |
| hydrologic flow (The characteristic behaviour and the total quantity of water involved in a drainage basin, determined by measuring such quantities as rainfall, surface and subsurface storage and flow, and evapotranspiration) | caudal | |
| hydrologic flow | caudal |
