Abstract
In the design of engineering structures such as overflows, sewers, flood control plans and water resources management, there is a need to obtain the maximum flood flow. Despite the statistical deficiencies and the absence of hydrometric stations in most of the small areas, choosing the appropriate methods according to the specific conditions of each area becomes very important. The current research, which has been carried out, examines several experimental methods of flood discharge estimation. Among the methods used in this research, we can mention Fuller, Krieger, Deacon and other methods based on the domain level. The results of the research show that the SCS method has the ability to significantly improve the accuracy and estimation of the flood discharge by taking into account the temporal and spatial characteristics. This progress in research has not only improved the understanding of flood behavior in the studied basins, but also seems to be a powerful tool for flood hydrograph analysis and accurate estimation of flood discharge in basins. Therefore, the results of the research will not only play a fundamental role in improving the understanding of water resources, but also have great importance in maintaining the stability of aquifers. In general, the results of this research have not only improved the understanding of flood behavior in the studied basins, but also show It is the fact that the use of SCS method can provide us with the analysis of the flood hydrograph and the accurate estimation of the flood discharge of the basins.
