Abstract

The phenomenon of flood, in spite of all its complexities, can be studied and appropriate solutions can be sought to control and reduce its damage and even economic exploitation of floods. On the other hand, before constructing any hydraulic structure such as dams, overflows, diversion channels, temporary dams, etc., it is necessary to have the information of maximum possible flood and flood hydrograph with different return periods in order to estimate the magnitude of different floods and predicted the maximum height of the river flood zone, the maximum area and width of the river flood in different areas, the maximum flow velocity, changes in shear stress, flood volume, changes in landing number and hydraulic radius, etc. flood routing and zoning operations or quantifying river confluence for flood alert systems. in this study, by selecting the case of Sivand river in fars province in the specified time period, flood frequency analysis was performed with the help of Smada and Easyfitt software and the maximum flood discharge was determined with different return periods. then, by selecting tangbolaghi hydrometric station as the representative station of Sivand river, hydraulic flood routing and zoning operations were attempted by Mike11 computer model.
