Threshold of Precipitation for Qinhe River Basin Flood Based on HBV Model
In impact assessment of floods in Qinhe Basin,with serious damages of these events,it is necessary to calculate the thresholds of precipitation.The conceptual semi-distributed hydrological model (HBV) was applied to define the threshold of precipitation (TP) for Qinhe River Basin flood,considering correlation between the water level and runoff.Daily temperature,precipitation and daily stream flow of 1977-1988 were used for calibra tion and verification of HBV model respectively.Taking Qinhe flood in 1982 as the example,the reasonable TP was validated based on the daily water level and flood disaster records.It was found that the third grade of TP was reasonable,which could be used to early warning for Qinhe River Basin flood.
