抄録

A short description of the nature-conservation orientated control work of the SABO-Garden in Miyajima island near Hiroshima is given. The principle of self-organization in a torrent (“boulder river”) is developed and defined. The rivers are also considered as an energetic system, frequency of the hazardous events and the stability of self-organizing structures are depicted and the destruction mechanism of the structures is described. Long-term considerations of superposition of different processes are shown and proposals for designing control works are given.
