Abstract

This paper aims to improve the understanding of the dynamics of sedimentary structures at the reach scale using a field approach. The AA. investigated the dynamics of sedimentary structures in three 15 m long reaches of a small gravel-bed river, (Moras Creek, Québec), characterized by moderate slope and high relative roughness. The results show that the rapid adjustment of the bed is associated with the development of key sedimentary structures anchored by the large boulders. At the reach scale, these structures increased the probability of congested areas in the displacement of bed material. In both control sections, sedimentary structures were maintained during the experiment
