This sedimentary gap also concerns the entire alluvial record of NE Morocco, which extends from 8700 to 7300 cal. BP thus reveals a long-term entrenchment of the river bed, which probably contributed to post-depositional erosion of alluvial deposits related to the 8.2 or 7.6–7.3 ka events. These indices demonstrate clear afforestation and increasing floodplain stability associated with the return of humid conditions ca. The high-resolution Cha07 record provides detailed information on hydrological responses of the river catchment to climatic variations between the 8.2 and 7.6–7.3 ka RCCs. Our fluvial record suggests a probable forcing of short-term solar variability on the Moulouya river activity during this interval.
