Quarry reclamation in the Lombardy plain, Italy
Abstract The hydrogeological and geotechnical problems involved in the reclamation of quarries in the Lombardy plain are put forward, and some general criteria to solve such problems are suggested. Subsoil lithology is essentially formed by alluvial, highly pervious, non-cohesive soils, the grain size generally decreasing from North to South; during the last decades, several large and deep excavations for exploitation of sandy and gravelly aggregates have been made, and the reclamation of quarry areas has not to be considered. From the hydrogeological point of view, quarries are differentiated depending to whether or not they reach groundwater level; moreover, instability problems due to quarry/river interactions are investigated. From the geotechnical point of view, the problems depend on the excavated soil, on the filling material and on land use; slope stability and correction, and bottom and lateral watertightness are of primary importance. As alternatives to geomembranes, semi-permeable, compacted soil and soil/bentonite layers can often be used to achieve a satisfactory watertightness.
