There are various models for flood prediction that are based on different conceptual basis. The current SCS-CN model is a well-known model in this field that is widely used in Iran and other countries. Recent researches focuses on improvement of this model and improve its efficiency but it is necessary to evaluate the improved models for catchments of Iran. The objective of this study is the comparison of current SCS-CN and developed Mishra-Singh (One Parameter) models for flood hydrograph and peak estimation using data of five catchments in Golestan province.
Study Area and Used Data
Five catchments (including Galikesh, Tamer, Kechik, Vatana and Nodeh) located in Golestan province were considered to evaluate different models for flood hydrograph estimation. The characteristics of the selected basins are presented in Table
