| flood forecast (The hydrological processes generating river floods have been studied extensively and several modelling concepts have been proposed. The standard procedure for flood forecasting consists of calibrating the parameters of the model of a particular river basin on a representative set of historical hydrometric data and subsequently applying this calibrated model in a real-time environment) | árvíz előrejelzés | |
| flood protection (Precautionary measures, equipment or structures implemented to guard or defend people, property and lands from an unusual accumulation of water above the ground) | árvízvédelem | |
| flood runoff (The total quantity of water flowing from the catchment during the period of the flood) | árvíz lefolyás | |
| flooding (A general and temporary condition of partial or complete inundation of normally dry land areas from the overflow of inland and/or tidal waters, and/or the unusual and rapid accumulation or runoff of surface waters from any source. A great flow along a watercourse or a flow causing inundation of lands not normally covered by water) | árvízi elöntés | |
| flora (biology, The plant life characterizing a specific geographic region or environment) | növényvilágbiológia | |
| flora (A work systematically describing the flora of a particular region, listed by species and considered as a whole; document) | növények | |
| flora restoration (The process of returning plant ecosystems and habitats to their original conditions) | növényzet helyreállítása | |
| flotation (A process used to separate particulate solids by causing one group of particles to float; utilizes differences in surface chemical properties of the particles, some of which are entirely wetted by water, others are not) | flotáció/úsztatás | |
| flow field (The velocity and the density of a fluid as functions of position and time) | ártér | |
| flower (The reproductive structure of angiosperm plants, consisting of stamens and carpels surrounded by petals and sepals all borne on the receptacle) | virág | |
| flowering plant (Plants capable of producing conspicuous flowers) | virágos növények | |
| flowing water (Moving waters like rivers and streams) | áramló víz | |
| flowing water | folyóvíz | |
| flue gas (The gaseous combustion product generated by a furnace and often exhausted through a chimney (flue)) | füstgáz | |
| fluidics (A control technology that employs fluid dynamic phenomena to perform sensing, control, information, processing, and actuation functions without the use of moving mechanical parts) | fluidika | |
| fluidised bed (1. A system for burning solid carbonaceous fuel efficiently and at a relatively low temperature, thus minimizing the emission of pollutants. The fuel is crushed to very small particles or a powder and mixed with particles of an inert material. The mixture is fed into a bed through which air is pumped vertically upwards, agitating the particles so they behave like a fluid. The forced circulation of air and the small size and separation of fuel particles ensures efficient burning. 2. A bed of finely divided solid through which air or a gas is blown in a controlled manner so that it behaves as a liquid) | fluidágy | |
| fluidization (A roasting process in which finely divided solids are suspended in a rising current of air (or other fluid), producing a fluidized bed; used in the calcination of various materials, in the coal industry, etc.) | fluidizálás | |
| fluoridation (The addition of the fluorine ion to municipal water supplies in a final concentration of 0.8-1.6 ppm (parts per million) to help prevent dental caries in children, addition of fluor(ide, ions) to (drinking) water) | fluorozás | |
| fluorinated greenhouse gas | fluortartalmú üvegházhatású gáz | |
| fluorinated hydrocarbon | fluorozott szénhidrogén |
