  • Discrimination of alluvial and mixed bedrock–alluvial multichannel river networks
  • This paper explores the use of planview morphological metrics to quantitatively describe and distinguish mixed bedrock–alluvial multichannel networks from alluvial multichannel networks. The geometries of the channel planforms of 2 bedrock
  • -constrained networks (Mekong and Orange rivers) are compared with the classic alluvial anastomosed Upper Columbia River and the wandering Ganga River. Widely recognized indices utilized include : channel link count and channel sinuosity, and less common
  • convexity clearly discriminates the 2 alluvial rivers from the 2 bedrock-influenced rivers. The width of the macrochannel, in which each network develops, has a positive influence on the number of channel links and is further related to channel slope

  • Sediment production and yield from an alluvial gully in northern Queensland, Australia
  • Sediment production, transport and yield were quantified over various timescales in response to rainfall and runoff within an alluvial gully, which erodes sodic soils of a small floodplain catchment along the Mitchell River, northern Australia
  • the hypothesis that partially or fully transport-limited conditions predominated along the alluvial gully outlet channel.

  • Stratigraphic architecture and alluvial geoarchaeology of an ephemeral fluvial infilling : Climatic versus anthropogenic factors controlling the Holocene fluvial evolution in southeastern Spain drylands
  • Two stages of depositional high-discharge fluvial environments are recorded in the infilling of a rock shelter in a canyon of the Segura River : (1) aggradational alluvial gravels in the lower part, interpreted as braided channel bars (7000 to 2030

  • Calcrete-coated remnants of landslide debris and alluvial deposits are exposed along the hillslopes of the Soreq drainage, Judea Hills, Israel. These remnants indicate that a transition from landslide-dominated terrain to dissolution-controlled

  • Large floods, alluvial overprint, and bedrock erosion
  • alluvium covers the bedrock and typical alluvial channel forms (meandering or braiding patterns, armour layers or bedforms) develop, which influence sediment transport rates. The overprint effect is illustrated using field data from the Erlenbach
