Catastrophe revisited

Abstract. Catastrophic flow failures have occurred with alarming frequency in mine tailings dams and dumps of discards and other mine waste. In recent years, catastrophic flow failures have also occurred in dumps of municipal solid waste and even in what were intended to be carefully controlled and well-engineered landfills.
