| hidroelektrostacija |
hydroelectric power plant (Power station which operates with the free renewable source of energy provided by falling water) |
|
| hidrogrāfija |
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) |
|
| hidrogrāfiskais baseins |
hydrographic basin (1. The drainage basin of a stream. 2. An area occupied by a lake and its drainage basin) |
|
| hidrogrāfiskais tīkls |
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) |
|
| hidrokultūra |
hydroculture (Growing plants without soil but in sand or vermiculite or other granular material, using a liquid solution of nutrients to feed them) |
|
| hidrolīze |
hydrolysis (1. Decomposition or alteration of a chemical substance by water. 2. In aqueous solutions of electrolytes, the reactions of cations with water to produce a weak base or of anions to produce a weak acid) |
|
| hidroloģija |
hydrology (The science that treats the occurrence, circulation, distribution, and properties of the waters of the earth, and their reaction with the environment) |
|
| hidroloģiskā plūsma |
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) |
|
| hidroloģiska katastrofa |
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) |
|
| hidroloģisks cikls |
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) |
|
| hidroloģisks līdzsvars |
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) |
|
| hidrometeoroloģija |
hydrometeorology (That part of meteorology of direct concern to hydrologic problems, particularly to flood control, hydroelectric power, irrigation, and similar fields of engineering and water resource) |
|
| hidrometrija |
hydrometry (The science and technology of measuring specific gravities, particularly of liquids) |
|
| hidrosfēra |
hydrosphere (The waters of the Earth, as distinguished from the rocks (lithosphere), living things (biosphere), and the air (atmosphere). Includes the waters of the ocean; rivers, lakes, and other bodies of surface water in liquid form on the continents; snow, ice, and glaciers; and liquid water, ice, and water vapour in both the unsaturated and saturated zones below the land surface. Included by some, but excluded by others, is water in the atmosphere , which includes water vapour, clouds, and all forms of precipitation while still in the atmosphere) |
|
| hidrotehnika |
hydraulic engineering (A branch of civil engineering concerned with the design, erection, and construction of sewage disposal plants, waterworks, dams, water-operated power plants and such) |
|
| higiēna |
hygiene (The science that deals with the principles and practices of good health) |
|
| hiperteksts |
hypertext (The organization of information units typically containing visible links that users can select or click with a mouse pointer or some other computer device to automatically retrieve or display other documents) |
|
| hlorēšana |
chlorination (The application of chlorine to water, sewage or industrial wastes for disinfection or other biological or chemical purposes) |
|
| hlorēts ogļūdeņradis |
chlorinated hydrocarbon (A class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain. Among them are DDT, aldrin, dieldrin, heptachlor, chlordane, lindane, endrin, mirex, hexachloride, and toxaphene. In insects and other animals these compounds act primarily on the central nervous system. They also become concentrated in the fats of organisms and thus tend to produce fatty infiltration of the heart and fatty degeneration of the liver in vertebrates. In fishes they have the effect of preventing oxygen uptake, causing suffocation. They are also known to slow the rate of photosynthesis in plants. Their danger to the ecosystem resides in their rate stability and the fact that they are broad-spectrum poisons which are very mobile because of their propensity to stick to dust particles and evaporate with water into the atmosphere) |
|
| hlorīds |
chloride (A compound which is derived from hydrochloric acid and contains the chlorine atom in the -1 oxidation state) |
