- Abstract:
- This study uses fractal analysis to make a fractal drainage model, a new way to determinate the complexity of watershed. The drainage model is a graphical representation considering the logarithmic scale of the number, length and average length of the river segments of a different order. The drainage model of Jijila watershed was based on classifications elaborated by Strahler and Zavoianu using fractal analysis. This morphometric model allows the observation of qualitative and quantitative inter-determination of the watershed. The fractal analysis of river segments reflects the over-execution of the Jijila watershed due to the elongated development of the watershed, asymmetry, low average gradient. Hence, the Jijila watershed should have more of 2nd and 3rd order river segments. The morphometric analysis was made in the watershed Jijila, a small river in the South-East Romania, Dobrogea, from Macinului Mountains. The fractal analysis of the fractal drainage model was made using topographic maps of 1:50000 scale, geological map of 1: 200000 scale and field trips. The Image J 1.51 software for image processing and Benoit software to determinate the fractal dimension box-counting of the river's watershed were used. Our research confirms the hypothesis that the fractal drainage model confirms over-realization of the Jijila watershed, and it may be further successfully used. This model has the big advantage that it does not require measurements of number, length and the average length of river segments, preventing errors that may be introduced by the determination of lengths and average lengths.
