The distribution of piping in Britain has been studied from a survey of 74 piped basins, and a number of in-depth studies at the individual basin scale. This was undertaken to determine the factors controlling the distribution of piping at 2 scales
, the broad national distribution and the distribution at the scale of individual basins.
In the Ebro Basin, piping is an ubiquitous erosion process in badland areas, occuring in 2 main situations : on slopes of exposed Tertiary clays and in recently incised silty-clay Holocene valley-fill sediments. The quantitative importance
