  • Slope failures in municipal solid waste dumps and landfills: a review

    Between 1977 and 2005 six large-scale failures of municipal solid waste dumps and landfills have been recorded in the technical literature. The volumes of waste mobilized in the failures varied from 10—12 000 m3 in a failure that killed nearly 300 people to 1.5 million m3 in a failure that caused no deaths or injuries. Of the six failures, four occurred in dumps that, as far as is known, had not ...
