Abstract

Debris flows are common phenomena along the “Serra do Mar”, a mountain range of about 800 to 1000 m high, running along the Southern Brazilian coastal area. This paper deals with the “Sabo Works”, i.e., structures to control debris-flows, proposed for an area of the “Serra do Mar”, in Cubatão, São Paulo-Brazil. The Brazil-Japan cooperation in the mid-1980 is described, followed by a brief history of past events that affected a PETROBRAS large oil refinery located in the area. A description of the phenomenon and the conditions for its occurrence are presented. The concepts and functions of the proposed “sabo works” are pointed out, stressing that they intended to protect the refinery installations and to preserve the environment.
