The AA. examine some of the detailed characteristics of this cellular computer model. They show the qualitative form of the braiding produced by the model is generally insensitive to changes in most of the numerical parameters used in the model. The most crucial parameter choice is the use of a non-linear exponent (>1) to describe the relation between sediment flux and local stream power. In addition, the AA. show that there is a simple and apparently fundamental connection between braided-stream channel networks and erosional (dendritic) networks that has not been previously recognized
