Sandpiles and river networks: extended systems with nonlocal interactions Academic Article uri icon

abstract

  • Abstract A proposed continuum model of sandpile growth is able to demonstrate instantaneous long-range interactions and sudden collapses typical of real sandpiles. The model is shown to be equivalent to an evolutionary quasivariational inequality. In the limiting case of zero angle of repose the inequality describes water transport in a river network.
