In the Bardenas regíon we recognize some hydric erosion processes, as follows: sheet-wash and runof/' rilling, badlanding and forming of gullies with Vand U section". This last type is relationed with certain piping forms, that indicate the importance of the subsurface eros ion at these points. We propose a classification for those forms, and an erosional cycle ofpiping. The anthropic inciden ce of this erosion type in the area is also considered.
