  • Bardenas Reales badlands are located in the middle-western sector of the Ebro Depression, northern Spain. Several erosion processes operate in the Bardenas Reales : rilling, gullying, piping and mass movements. The relative role played
  • favor piping, gullying and rilling during the rainfall maxima. Soil erodibility in this area is clearly controlled by the sodium content and the presence of swelling clays. These factors determine the distribution and appearance of piping processes
  • . Cracking in Holocene clay deposits, devoid of swelling clays, is related to high sodium content that confers a dispersive character. Clay dispersion causes loss of cohesion favoring piping.
  • Influencia de los procesos de piping en la evolución del modelado : Bardenas Reales (Navarra, España)
