Caldarelli, Guido and Giacometti, Achille and Maritan, Amos and Rodriguez-Iturbe, Ignacio and Rinaldo, Andrea Randomly pinned landscape evolution. Physical Review E, 55 (5). R4865-R4868. ISSN 1539-3755 (1997)Full text not available from this repository.
A simple scheme for the evolution of a fluvial landscape in heterogeneous environments is critically examined to capture the essential mechanism responsible for the recurrent scale-free landforms in the river basin. It is shown that, regardless of boundary and initial conditions, geomorphological constraints in the form of quenched randomly pinned regions play a key role in the robust emergence of aggregation patterns with a scaling behavior in agreement with that of real river basins.
