... of lumps of typical dimensions from a few millimetres to a few hundred millimetres. The age of the fills is about 20 to 30 years and over this period they generally remained unsaturated down to the depths of 15 to 20 metres. Laboratory experiments with a model double porosity clayey material revealed high...
