Badlands in the Tabernas Basin, Betic ChainCalvo-Cases, Adolfo; Harvey, Adrian M.; Alexander, Roy; Cantón, Yolanda; Lázaro, Roberto; Solé-Benet, Albert; Puigdefábregas, Juan; University of Valencia, University of Liverpool, University of Chester, University of Almería, CSIC, Almería (Springer, 2014-04-19)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 SpainMaher, Elizabeth; Harvey, Adrian M.; France, Derek; University College Chester ; University of Liverpool ; University College Chester (Elsevier, 2007-02-28)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.
