  • The catena principle in geomorphology
  • Analyse de système ; Catena ; Géographie physique ; Géomorphologie ; Théorie
  • All landscapes (in humid climates) can be considered as a superposition and juxtaposition of catenas , each catena consisting on top of a flat eluvial, in the middle of a steep colluvial and at the bottom of a flat alluvial zone. Catenas had
  • originally been observed in connection with soil surveys| here it is maintained that they have a much deeper systems-theoretical significance.

  • The AA. describe catenas developed on calcareous moraines of Pinedale and Bull Lake ages at Whikey Basin on the eastern flank of the Wind River Range, Wyoming, in 2 separate valleys. Both catenas in both valleys contain primary carbonates
  • but there are topographic differences between them. The AA. suggest that differences in catena development mostly result from the differences in slope length between the jakey's Fork and Torrey Creek catenas.
