Abstract

In this paper, natural step-pool geometry is compared with steep alluvial channels where grade-control structures such as check-dams and bed sills make the stream profile resemble a natural stepped stream. In order to test the hypothesis that natural pools are analogous to pools formed below grade-control works with respect to their dimensions, shape and formative dynamics, 37 natural pools and 73 artificial pools were surveyed in 10 mountain streams of the eastern Italian Alps. The results lend support to an upstream-forced cascade model for step-pool formation, where the energy of falling jets controls the geometry of the pools, and is therefore regarded as the most important scaling-independent variable
