Lux vs Innichen - San Candido

Informations

The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception.

In English, "lux" is used as both the singular and plural form.The word is derived from the Latin word for "light", lux.

The Drava or Drave (German: Drau, pronounced [ˈdʁaʊ] (listen); Slovene: Drava [ˈdɾàːʋa]; Croatian: Drava [drǎːʋa]; Hungarian: Dráva [ˈdraːvɒ]; Italian: Drava [ˈdraːva]) is a river in southern Central Europe. With a length of 710 kilometres (440 mi), 724 kilometres (450 mi) including the Sextner Bach source, it is the fifth or sixth longest tributary of the Danube, after the Tisza, Sava, Prut, Mureș and perhaps Siret. The Drava drains an area of about 40,154 km2 (15,504 sq mi). Its mean annual discharge is seasonally 500 m3/s (18,000 cu ft/s) to 670 m3/s (24,000 cu ft/s).

Its source is near the market town of Innichen/San Candido, in the Puster Valley of South Tyrol/Alto Adige, Italy. The river flows eastwards through East Tirol and Carinthia in Austria into the Styria region of Slovenia. It then turns southeast, passing through Croatia and, after merging with its main tributary Mur, forms most of the border between Croatia and Hungary, before it joins the Danube near Osijek.
