摘要：
Data from six small watersheds were utilized for developing a regional runoff frequency curve for small watersheds in the Hirakud catchment of eastern India. Five probability distribution Junctions were tested by comparing the residual sum of square, and a two-parameter log-normal distribution was found to be the best probability distribution function for use in the eastern region of India. A regional runoff frequency curve was generated using the index flood method. The students T-test revealed that the regional runoff frequency curve estimate was not statistically different from a log-normal estimate at the 0.01 significance level.
