Torrente (torrent)
Torrente (of Italian torrente , Gießbach ') is called in the Mediterranean a only after heavy rainfall as torrent stream occurring from the mountains.
The Torrente has a wide, often deeply incised bed ( gorge , canyon ) filled with rubble , which sometimes largely or completely dries out when there is no rainfall, but sometimes also carries water permanently. What is characteristic, however, is the underflow or estuary, which usually falls completely dry. In general, the normal water seeps away here in the gravelly mountain foreland, so that the river can also be a permanent underground aquifer . Otherwise it is mostly rivers from a karst area , in which only heavy downpours or the snowmelt does not seep into the subsoil permanently.
The torrent valleys as well as the closely related with them are Arrojos or Bajadas (Spanish term for gravel valleys, which also only occasionally or periodically run water) to the dry valleys , the respective waters to the (mostly intermittent ) dry rivers . Torrents (torrentes) can be found in the Mediterranean as well as in the semi-humid and semi-arid subtropics , e.g. B. in deserts like the wadis of the Sahara, the Riviers in Namibia or the Creeks in Australia, or on volcanic islands like Réunion , as well as in the subpolar and subnival areas.
