Abstract:Runoff calculation is a key step to control the urban flood and to evaluate the efficiency of soil and water conservation. This study combined the data of soil and typical rainfall events in Yuyao area, and conducted an in-depth analysis on the relationship among precipitation, early loss of rainfall, maximum potential infiltration and runoff. Furthermore, SCS extending model applicable to plain river-net regions based on land use functions was established, and was validated in Yuyao rainfall-runoff. Results showed that the absolute error between the calculated and observed runoffs based on SCS extending mode was in the range from 0.14 to 1.36 mm, indicating good consistency.
