| Terms for subject Environment (24829 entries) |
| hydrographic network | Hydrographisches Netz | |
| 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) | Hydrographisches Netz | |
| hydrographic survey | hydrographische Vermessungstätigkeit | |
| 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) | Hydrographie | |
| hydrologic balance | Wasserbilanz | |
| 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) | Wasserbilanz | |
| 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) | Wasserkreislauf | |
| 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) | Wasserkatastrophe | |
| hydrologic flow | Wasserfluß | |
| 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) | Wasserfluß | |
| hydrological regime regulation | Regulierung des Gewässersystems | |
| hydrological risk | hydrologisches Risiko | |
| hydrology (The science that treats the occurrence, circulation, distribution, and properties of the waters of the earth, and their reaction with the environment) | Hydrologie | |
| Hydrology and Water Resources Programme | Hydrologie- und Wasservorräteprogramm | |
| 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) | Hydrolyse | |
| hydrolysis rate | Hydrolysegeschwindigkeit | |
| hydrolytic enzymes | hydrolytische Enzyme | |
| hydrolytic tank | Hydrolysebehälter | |
| 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) | Hydrometeorologie | |
| hydrometry (The science and technology of measuring specific gravities, particularly of liquids) | Hydrometrie |
