      The complex badland landscape at Tabernas results from a combination of relief amplitude generated by tectonic uplift since the Pliocene and reactivated several times during the Pleistocene, the properties of the Tortonian sedimentary rocks and a predominantly arid climate. The landscape is dominated by deep incision of the main river systems, which continues in part of the headwater tributaries, and characterized by contrasting slope morphologies and a variety of microecosystems. The Tabernas badlands exhibit a diversity of landforms resulting from the combination of multi-age soil surface components that allow a variety of processes to operate at different rates. These are dominated by rilling and shallow mass movements on south-facing hillslopes. On old surfaces and north-facing hillslopes, where biological components are present, overland flow with variable infiltration capacity and low erosion rates prevail. Incision in the gully bottoms occurs in the most active areas.
    • The impact of a major Quaternary river capture on the alluvial sediments of a beheaded river system, the Rio Alias SE Spain

      This article discusses a major river capture event within the Sorbas Basin (c.70 ka) which created a situation whereby the Rio Alias abruptly lost c. 70% of its drainage area and this led to a significant modification of the fluvial system in both upstream and downstream zones on the capturing stream, and downstream on the beheaded system.
