| Terms for subject Environment (6310 entries) |
| ūdens dzirnavas | water mill (A mill whose power is provided by a large wheel which is turned by moving water, especially a river) | |
| ūdens ekoloģija | aquatic ecology (The study of the relationships among aquatic living organisms and between those organisms and their environment) | |
| ūdens ekosistēma | aquatic ecosystem (Any watery environment, from small to large, from pond to ocean, in which plants and animals interact with the chemical and physical features of the environment) | |
| ūdens enerģija | water power (Energy obtained from natural or artificial waterfalls, either directly by turning a water wheel or turbine, or indirectly by generating electricity in a dynamo driven by a turbine) | |
| ūdens erozija | 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) | |
| ūdens hiacinte | water hyacinth (Floating aquatic plant, Eichornia crassipes of tropical America, having showy bluish-purple flowers and swollen leafstalks: family Pontederiaceae. It forms dense masses in rivers, ponds, etc., and is a serious pest in the southern U.S., Java, Australia, New Zealand, and parts of Africa) | |
| ūdens ieguve | water extraction (Pumping of water for different purposes (i.e. agriculture, land reclamation, domestic and industrial use, etc.)) | |
| ūdens iesūkšanās | water seepage (The slow movement of water through small openings and spaces in the surface of unsaturated soil into or out of a body of surface or subsurface water) | |
| ūdens infiltrācija zemē | water infiltration into the ground (The movement of surface water into soil or rock through cracks and pores) | |
| ūdens izcenojums | water pricing (Applying a monetary rate or value at which water can be bought or sold) | |
| ūdens izmantošana | 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) | |
| ūdens kaitējums | water damage (Water damage can be caused by flooding, severe storms, tidal waves, seismic seawaves, storm surges, etc.) | |
| ūdens korozijaktivitāte | water corrosivity (Complex series of reactions between the water and metal surfaces and materials in which the water is stored or transported. The corrosion process is an oxidation/reduction reaction that returns refined or processed metal to their more stable ore state. With respect to the corrosion potential of drinking water, the primary concerns include the potential presence of toxic metals , such as lead and copper) | |
| ūdens kvalitāte | water quality (A graded value of the components (organic and inorganic, chemical or physical) which comprise the nature of water) | |
| ūdens kvalitātes direktīva | water quality directive (EC Directive establishing the rules relating to water for human consumption) | |
| ūdens kvalitātes pārvaldība | water quality management (Water quality management concerns four major elements: the use (recreation, drinking water, fish and wildlife propagation, industrial or agricultural) to be made of the water; criteria to protect those uses; implementation plans (for needed industrial-municipal waste treatment improvements) and enforcement plans, and an anti-degradation statement to protect existing high quality waters) | |
| ūdens kvalitātes uzlabošanās | water quality improvement (Progress in, or betterment of, the environmental condition and integrity of water) | |
| ūdens lauksaimniecības vajadzībām | water for agricultural use (Water used in agriculture for irrigation and livestock. Livestock watering is only 1 percent of the total water withdrawal for agricultural use. Of all functional water uses, irrigation is the largest agricultural use of water) | |
| ūdens līmenis | water level (The level reached by the surface of a body of water) | |
| ūdens masa | water bottom (The floor upon which any body of water rests) |
