Distribution of bedrock channel erosion: micro and mesoforms in fluviokarstic canyons

Abstract

This paper examines erosional forms and processes in a calcareous bedrock channel, in the Tambuc rambla (Caroig platf orm, Valencia). The analysis of forms demonstrates the dominance of abrasion, erosion and quarrying over corrosion processes. The incision caused by channel fl ow (forming flutes, potholes and inner channels) has been more eff ecti ve than other produced by dissolution (resulting in kamenitza and rillenkarren). The hydrodynamic processes, which are strongly structurally influenced, produce an irregular longitudinal profile with several knickpoints.
