Open-pit mining exploitation of useful mineral deposits involves occupancy and affectation of large areas of land, with negative effects on medium and long term. Although the impact of mining operations can not be avoided during the exploitation, it can be reduced and, after the cessation of the mining activities, it can be offset. The impact of open-pit mining exploitation occurs primarily on the land by radically changes on the morphology and geomorphology of the land, by modification of the geotechnical charact...

The flooding of the remaining gaps of the former quarries is a process that can be achieved naturally, by influx of water from various permanent and/or temporary sources such as rainwater, superficial water courses, underground water or artificially, through water adductions from other nearby water sources like rivers, lakes etc. Knowledge of hydrographical, hydrological and hydrogeological conditions specific to a region where open-pit mining operations are carried out allows the assessment of the available water...
