Field studies conducted in Dinosaur Park badlands, Alberta, Canada, Chinguacousy badlands, Ontario, Canada and Sestino badlands, Tuscany, Italy, have shown that there are 2 dominant clay-rich lithologies : smectite-rich and smectite-poor mudrocks
. Clay minerals have an important role in defining surface and subsurface processes on badland hillslopes. Badland materials were monitored in controlled laboratory conditions during an incremental weathering experiment. It is highlighted that knowing

Rainfall simulation experiments are widely used in geomorphological research in badland areas. This technique contributed significantly to our understanding of badland geomorphology in the Mediterranean belt. This study confirmed that rainfall
simulations are well suited to 1) analyse runoff-infiltration processes and sediment detachment within badlands, and 2) to establish the factors determining the hydrological and erosion response at interrill scale in badland areas. Rainfall simulations

Vegetation was not a subject of research in early papers, which contrasts with the present situation when about 40% of papers published in international journals about badlands address some aspect of vegetation. However, the growth in the attention
paid to vegetation and erosion rates was not linked to any increase in papers dealing with badland reclamation. Badlands are now seen as a group of systems with some common features but diverse dynamics, depending mainly on climatic and lithological
drivers. More attention should be paid in the future to investigating the evolution of these landforms over time, mostly through modelling studies. Although some badland areas determine on- and off-site environmental issues, others are spots of landscape

The AA. review 40 years of research in the Zin Valley Badlands in Israel to reconcile some of the conflicting results observed there and develop a perspective on the function of badlands as model landscapes. While the data collected in the Zin
Valley clearly confirm that spatial and temporal patterns of geomorphic processes and their interaction with topography and surface properties have to be understood, the AA. still conclude that the process of realizing complexity in the simple badlands

Suspended sediment transport is probably the main process in sediment export from badland areas. In the Araguás catchment (central Pyrenees) there is a statistically significant positive linear relationship between maximum discharge and the maximum
with the corresponding discharge value. It is highlighted that the evaluation of sediment yield from badland areas using turbidity values involves significant uncertainty, and quantitative estimates of the errors involved are provided.

and vegetated surfaces. Parent materials properties are discussed with respect to the initiation and development of different badlands processes. In particular, clay dispersivity at different depths in the sample sites is examined as a well-known controlling
factor of accelerated erosion, thus providing some interesting clues for understanding the spatial variability of denudation rates in the considered badlands sites.

sols hétérochrones. Le plus grand ravinement date de la fin du Pléistocène – début de l’Holocène et du temps actuel, moment de formation des badlands. Les dernières étapes de l’érosion sont fortement liées à l’action anthropique (défrichement des pentes
