From the point of view of fractal behaviors, the property of replication over time creates patterns in the bed of the basin that show unique performance during the maturity of a basin, depending on the reproductive characteristics and how they change. For this reason, in this study, investigates the bifurcations of drainage networks of the Ramhormoz basin using Tokunaga model and fractal dimension correlation, has been done. Ramhormoz River is one of the sub-basins of Jarahi basin located in the southwest of the country. This river originates from 50 km southeast of Izeh and flows to the southwest. In this study, river networks were extracted from Arc GIS software, and then input data were entered into the software to calculate two-dimensional fractal numbers using correlation function. In this regard, first Ramhormoz basin is divided into eastern and western parts and then using the Tokonaga method, irregular network and curve of Ramhormoz river are drawn in a regular, geometric and corresponding tree form. According to the length of the streams, the fractal dimension was calculated for both parts of the Ramhormoz basin. The fractal dimension of the correlation between the Ramhormoz basin and its eastern and western parts has been calculated between (1.42 to 1.68) with a high correlation coefficient, which indicates a relatively high turbulent behavior of the basin and its parts. The calculated fractal dimension represents the average bifurcation ratio and the short time to reach a constant flow.
