Flood Index and Its Forecast in Xinjiang River Basin
The qualitative concentration period of precipitation was quantitated in time and rainfall by using daily data. General equations of concentration period and concentration degree were formed. A single station flood index was given relating to precipitation concentration period,concentration degree and flood level. On this basis,precipitation concentration period,concentration degree and the flood index in Xinjiang River basin were determined. Finally,the forecast experiments were made with the flood index in the basin.
