Abstract: The relevant flood control capacity of a reservoir was taditionally calculated by designing flood hydrograph and by regulating flood. Then what about the error of this simplified method? This is a problem which the hydrologists have paid more and moreattention to. The aim of this paper is to make an analysis and comparison of the above mentioned methods by way of statistics and experiments, or the Monte Carlo Method(M-C).The method recommended in this paper is like this:set up a flood hydrograph model on the basis of the flood feature of a certain river-basin:simulate enough flood hydrographs with the M-C Mehtod; regulate the floods one by one according to the reservoir flood-releasing rules and then a flood control result will be achieved that can meet the designed standard.This method is compared with the traditional one soas to provide some references for a more reasonable method in calculating the flood control capacity of a reservoir.
