Palaeo-hydrological field investigation was carried out in the middle reaches of the Jinghe River. A set of palaeoflood slackwater deposit beds was identified in the Holocene loess-soil sequence in the riverbanks. The analytical results showed that the palaeoflood slackwater deposits have recorded extraordinary flood events in the Jinghe River valley. According to stratigraphic correlation and OSL dating, the palaeoflood events were dated to 4100-4000 a BP. The palaeoflood peak discharges were estimated by using the hydrological model and checked by different approaches. These results have the flood data sequence of the Jinghe River extended to 10,000-year time-scale. It provided significant data for hydraulic engineering and for mitigation of flood hazards in the Jinghe River drainage basin
