This paper describes a computer model for organizing network system and outputting river parameter, for the usage of all kinds of river model. Making use of digital data input, GSMLW develops a “free, seriate tree”structure to handle the complicated river system and generate output data of river parameters. According to requirement, river parameters can vary with the curvature distance of river central lines or straight distance to the outlet.
There are three parts of this model, one is to find central lines of stream network, one is to identify influx points of tributaries, and the other is to compute river parameters and output data files. In the modeling, the critical technique is the “free, seriate tree” structure. This tree structure is adaptable to the random tree structure of a natural river system, and thus is efficient in river system modelling.
