Geomorphic features of a badland (biancane) area (Central Italy) : characterisation, distribution and quantitative spatial analysis
This paper characterises the morphology and distribution of the biancane forms, and analyses their spatial structure quantitatively, in order to identify a possible evolutionary trend between the forms, to assess the role of biancane evolution

In this study, factors including geological setting, material properties and terrain conditions are examined to better interpret the origin of biancane and calanchi in the Aliano badlands. The AA. provide an explanation for their origin, casting
Mineralogical and grain size composition of clays developing calanchi and biancane erosional landforms
Clayey terrains outcropping in many parts of Italy are frequently affected by accelerated erosion processes producing landforms known as calanchi (intensely dissected landscapes with rill and gully landforms) and biancane (bare cones and hummocks
). The factors controlling the development of these 2 landforms are still poorly understood. This study was undertaken to identify the material properties of calanchi and biancane.
Biancane badlands consisting of small domes dissected by rills and micropipes, with rough disordered microrelief, can be found along the Apennines in Italy. This study was undertaken in a residual area of biancane in southeast Tuscany to identify
the origins of micropiping and its influence on biancane evolution.

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
Characteritics badlands are incised into Plio-Pleistocene clays in Basilicata, creating steep, scarp slopes with knife-edge ridges (calanchi) and small dome-shaped forms (biancanes). This paper presents results from a 1997-2003 study into the rates
