From previous flume tests conducted in the framework of the OVERCOME Project, intended to investigate the effect of different soil materials, overflow discharges, and upstream face watertightness on the breaching processes of overflowed levee sections, we determined the need for further investigation on the effect of test repeatability, content of fines and armouring caused by the coarser particles. This document presents the results of this new set of tests which have shown an impact of these variables on the breach macro erosion processes, erosion rates and breach dimensions.
