Procesos de erosión en una zona de clima semiárido de la depresión del Ebro (Bardenas Reales, NE de España)

Some different erosion processes take place on the Bardenas Reales erosive depression: rilling, gullying, piping, mudslides, and armored mud balls.. The major or minor development of these processes is related with climatic conditions and physico-chemical characteristics of the materials. Precipitation distribution along the year conditions the presence of mudslides or armored mud balls. Physico-chemical conditions favour the formation of gullying and rilling. Other factors, such as slope, expedite runoff infiltration (needed for piping) and the slide of mudslides.
