RSN Code and Its Application Style

In This article, a self-similar river networks model was put forward, which use strings code to identify the original unit and the generator unit of RSN (Random Self-similar river Network). This strings code is consist of four parameters: the river networks price, the node number in generator unit, the angle between adjacent chains, and the probability of replacement of generator unit. Set the basic part of limit distribution of water system as the generator unit, and then use the Width Function (WF) of RSN to construct a Geomorphologic Instantaneous Unit Hydrograph (GIUH) based on WF, which was used to simulate hydrological response.
