Procesos de sedimentación ligados a flujos gravítacionales en regiones semiáridas. Un ejemplo del SE de España

In the studied area the rainfalls ofautum 1973 and 1989 led to the development of gravity flows of mud and/or debris flow type and their characteristic sediments. The analysis of rain fall conditions, processes and deposits reveals that the genesis of sediment by gravity in these areas had a catastr...

Descrição
Resumo:In the studied area the rainfalls ofautum 1973 and 1989 led to the development of gravity flows of mud and/or debris flow type and their characteristic sediments. The analysis of rain fall conditions, processes and deposits reveals that the genesis of sediment by gravity in these areas had a catastrophic and sporadic nature, and is controlled by the intensity and/or duration of rainfalls, the nature and thickness of the regolith in the slopes, the steepeness of these and development of the vegetal cover
