  • 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.
  • Badlands in marl lithologies : A field guide to soil dispersion, subsurface erosion and piping-origin gullies

  • landscape erosion. Surface crust character, ephemeral rills, and large subsurface tunnel settings are explained and classified. In a final section, the geomorphological implications of piping in gullied landscapes are explored by reference to the literature
  • The badlands of southwest Taiwan are characterized by sharp ridges, and are located in a tropical monsoon area that experiences contrasting rainy and dry seasons. Surface erosion predominates and subsurface erosion by piping is rather limited
