Short summary

Our study focuses on armor breakup and reformation in a laboratory experiment under conditions with limited sediment supply. We developed a novel technique that allows for measurement of the temporal and spatial changes of the bed surface texture during flow. The armor, which was formed under base flow conditions, broke up under a higher flow rate, which led to a fining of the bed surface and local degradation. Under continued peak flow a new armor formed that was coarser than the initial one.
