Properties of talus slopes composed of flat blocks

Auteur(s) et Affiliation(s)



Description :
In this paper the AA. draw attention to a rarer kind of talus slopes, the ones mostly formed by flat stones as building blocks. One case study in Norway is examined as an example typifying the properties of flat-blocks taluses. From comparisons of the geometrical characteristics and grain size distribution with taluses of the same rock type formed by regular blocks, remarkable differences are found, especially concerning the slope angle and the size distribution of blocks as a function of the distance from the headwall. To understand the formation dynamics of flat-block taluses, the AA. also carried out some simple experiments with flat blocks falling onto an experimental board.
