River network morphology not only reflects the structure of river stream but also has great effects on hydrological process, soil erosion, river evolution, and watershed topography. Here we propose and define a new sequence of self-similar networks and corresponding parameters for the generated Tokunaga network. We also discuss the topological and numerical characteristics of self-similar networks with different iteration rules by utilizing links and fractal dimension. Application results indicate that the ...

In a distributed hydrological model, the river basin un der study is usually divided into several sub-basins o even very small basic units. The rainfall-runoff proces of each basic unit is simulated by the way of modeling hydrological process of both the
