Abstract

This study examines recession rates of waterfalls in welded Aso-1 ignimbrite from the Aso volcano in southwestern Japan using an empirical equation, which comprises a force/resistance index composed of measurable geomorphic parameters. The estimated rates are then validated by examining the duration and distance of their recession. The contrast between the highly dissected landforms downstream of the present waterfalls and the gentle landscapes upstream of the waterfalls suggeststhat the rapid recession of the waterfalls is the major cause of post-eruptive fluvial erosion into ignimbrites
