| 摘 要： | Empirical equations relating runoff,maximum river stageand peak flow to rainfall were developed for the Tao riverdrainage basin at Li Jia Cun.A basin recession curve wasderived and a frequency analysis of extreme flood events wasconducted.Results showed that storm runoff was highlycorrelated with rainfall.However,maximum river stage andpeak flow were not as well correlated with rainfall.It wasfound necessary to separate rainfall into stratiform andconvective types.The magnitudes of the once-in-50 year,once-in-100 year and once-in-200 year events,calculated by thelog Pearson type Ⅲ distribution were closely equal to thoseestimated from a log-probability graph.Recommendations forimproving the predictive ability of the empirical equations arepresented.
