Analysis on Reduction and Consistency Correction of Watercourse Runoff Series

During water resources investigation and evaluation, in order to obtain a consistent natural annual runoff series under the conditions of recent underlying surface, the runoff series data should be revised in a consistent manner. Based on the series data of river runoff in Xiuwu-Baoquan-Hehe interval,the reduction calculation method of natural runoff, runoff series consistency analysis and correction method are discussed.
