SABO is the science, engineering and art of sediment disaster risk reduction. It has no real equivalent in the Western part of the world, nor outside Asia. At the laboratory, and from this lense, we are finding solutions to natural hazards and disaster risk reduction, climate change and sustainability issues, concentrating on the island arcs of Japan and Indonesia mostly.

PI: Prof. Christopher Gomez

Come and work, learn, enjoy SABO, Geomorphology and climate change hazards and disaster risks with us. Let's work towards sustainable communities.
