“…Traditionally, the development of piping has been associated with the presence of several conditioning factors: climate, physiography, and the inherent properties of soils or sediments (Jones, 1981;Bryan and Yair, 1982;Selby, 1982;Parker et al, 1990;Jones, 1994Jones, , 2004Faulkner et al, 2000, Desir andMarin, 2011;Goudie, 2013 In the central Ebro Basin, soil loss by piping is especially amplified in unconsolidated materials (mainly silts and clays) due to irrigation and the saline nature of the soil (García-Ruiz et al, 1997;García-Ruiz, 2011;Gutiérrez et al, 1997). In the Sariñena Basin, the salinity and sodicity of the soils and Miocene sediments, together with the low organic matter content of the soils (Tables 4 and 5), promote the structural instability and dispersibility of materials and their transport through the subsurface, as well as conspicuous surface soil erosion.…”
