Underlying the diversity of life and the complexity of ecology is order that reflects the
operation of fundamental physical and biological processes. Power laws describe empirical …

▪ Abstract This review proceeds from Luna Leopold's and Ronald Shreve's lasting
accomplishments dealing with the study of random-walk and topologically random channel …

David Knighton's best-selling book looks at the wide range of forms developed by natural
rivers and the processes responsible for that development. The book combines empirical …

Integrated, process‐based numerical models in hydrology are rapidly evolving, spurred by
novel theories in mathematical physics, advances in computational methods, insights from …

Biological communities often occur in spatially structured habitats where connectivity directly
affects dispersal and metacommunity processes. Recent theoretical work suggests that …

There is a large, popular, and growing literature on" scale-free" networks with the Internet
along with metabolic networks representing perhaps the canonical examples. While this has …

Stream power has a significant influence on many form and process attributes of the fluvial
system. Using a similar approach to that suggested by DM Lawler in 1992 and 1995, a …

A total of 15 rainfall simulation experiments were conducted in a 1 m by 2 m box varying
slope (10, 20, 30%) and rainfall intensity (60, 90, 120 mm h− 1). The experiments were …

Optimal channel networks (OCN's) obtained by minimizing the local and global rates of
energy expenditure evolve automatically from arbitrary initial conditions to network …

Self-organized criticality (SOC) has become a magic word in various scientific disciplines. In
the first ten years after Per Bak and his coworkers presented their seminal idea (Bak et al …
