The aim of this study is to discuss the mechanisms that determine the occurrence of badland forms in a subhumid mountain area in the Vallcebre area, southeastern Pyrenees, that has been subjected to detailed studies on physical weathering
and vegetation dynamics. Special attention is paid to the amounts of energy available for the main geomorphic agents (rainfall, freezing, clay shrinking) as well as to the explication of the preferred occurence of badland surfaces in north facing aspects.

L'évolution des badlands est influencée surtout par les processus de dénudation de l'argile nue. L'A. essaie d'évaluer les parts relatives du rôle du niveau de base, du climat et des conditions géologiques, et de dater l'origine du développement des
badlands dans la partie SE du plateau du Colorado en analysant les tendances régionales de la morphologie, les relations entre les badlands et la stratigraphie quaternaire qui sont datés au C. Les résultats sont comparés avec les études expérimentales
détaillées de deux interfluves de badlands équipés.

The aim of this paper is to determine whether processes operating in the past in badland areas of southern Africa were different from the present, by comparing contemporary badland processes operating in southern Africa with evidence found
in Quaternary sedimentary successions in badland areas.

Badland landforms, created in Plio-Pleistocene clay landscapes of the Basilicata region of southern Italy, form marginal features in a semi-arid landscape dominated by the widespread cultivation of subsidised cereals. These badland features are high
relative relief forms exhibiting a high drainage density and steep slopes, with slope angles typically in excess of 35°. The economically-driven change in land use from visually striking badland areas to newly remodelled fields for agricultural use results

In this paper Es is discussed for gullying and badland formation. Data from world literature have been collected and an Es-g table is presented from which interpolated values can be derived for prediction or postdiction. Applied to Mediterranean
badlands the latter operation yields a minimal age between 2,700 and 40,000 years which dates badlands in this belt back eventually to Upper Pleistocene times. Therefore, this application of the Es model is offered as a contribution to the still ongoing
discussion on the origin of badlands and their age.

A drainage basin simulation model is used to interpret the morphometry and historical evolution of Mancos Shale badlands in Utah. Field relationships and simulation modelling indicate that the badlands have resulted from rapid downcutting
of the master drainage below an Early Wisconsin terrace to the present river level, followed by base level stability. As a result, Early Wisconsin alluvial surfaces on the shale have been dissected up to 62m into steep badlands, and a Holocene alluvial surface
is gradually replacing the badland slopes which are eroding by parallel retreat.

This paper describes a preliminary study on a badland developed in temperate mediterranean climate and located in SW Tuscany (Italy). The selected site is characterized by biancane, domeshaped features a few meters in height, generally having
Soils, regoliths and their parent materials were investigated in relation to the developement of badlands (in the Pre-Pyrenees, in NE Spain) on Late Cretaceous mudrocks under a mountain Mediterranean Climate.
Une estimation du taux d'érosion a été effectuée dans deux régions de badlands du Bassin de l'Ebre (« El Barranco » et « La Charca »), en utilisant des techniques de mesures directes.
This paper outlines the geological characteristics of the area, the bioclimatic conditions, badlands evolution and the infiltrability of the Neogene marl regoliths, as well as correlations between rainfall, overland flow and soil erosion. Piping
erosion is shown to be a basic process in the formation of badlands in many parts of the Mediterranean morphoclimatic domain of South-East Spain.
The Araguás Catchment of the Central Spanish Pyrenees has been monitored since 2004 to study weathering erosion, as well as the hydrological and sediment responses to rainfall in order to understand the dynamics of a badland area in a relatively
