Abstract

The AA. investigate the connection between surface elevation and the growth and scaling of river networks. Three planar models (Scheidegger, Eden, and invasion percolation) are first considered. The AA. show that none of these planar growth models produces scaling results consistent with observations for natural river basins. The AA. then modify the models to include elevation, simulating the effects of fluvial erosion by enforcing the slope-area relationship. The AA. conclude that inclusion of the vertical dimension in these three models is critical for explaining the formation and regularities of fluvial networks
