Abstract

DESIGN FLOOD can be accessed through frequency analysis method by using probability principles and existing data. Short statistical series or missing data cause extrapolation uncertainty in appropriate assessment of DESIGN FLOOD. After accomplishment of studies for JAREH RESERVOIR DAM in Ramhormoz, big floods to the extent of discharge design of its spillways have occurred. Applying these data in flood series has caused remarkable changes in DESIGN FLOOD. The objective of this research is assessment and evaluation of DESIGN FLOOD of a reservoir dam based on flood statistical series. In this research, along with completion and evaluation of statistical accuracy of instantaneous maximum flood series, frequency analysis method has been used for assessment of design discharges. Flood Index Method has been used to determine flood hydrograph. The results indicate that the increase in magnitude of flood statistical sample not only changes the type of data STATISTICAL DISTRIBUTION, but also have a great impact on flood estimated values. This study shows an increase of 97% in peak discharge of spillways. The major differences refer to an increase of number of observations and magnitude of occurred flood events. The results of this research are useful in Jareh Dam as well as DESIGN FLOOD assessment of other dam development projects within the basin and the adjacent ones.
