A Simplex New Approach of Accounting Inflow Flood Hydrograph of Reservoir

摘要

This paper has detailedly analyzed rainfall, water-level and outflow hydrograph ac-cording to the over-dam inflow flood. The inflow flood recurrence interval was evaluated,and the coordinate of outflow peak that stands falling segment of the inflow hydrograph was found. The paper has pointed out why it is illogical that using water-balance account inflow flood hydrograph. It is most important that the paper has obtained a simplex triangle method of accounting inflow flood of the reservoir, gave out steps and discussed conditions. Special-ly, the result and analytical method in paper is referenced to supervisor and designer for mountain reservoirs.
