The geomorphic-based restoration of clay quarries in Tortosa, Catalonia, funded by the European Union's LIFE programme, utilized the GeoFluv-Natural Regrade approach. Despite constraints such as the inability to setback regrade pre-existing highwalls, the project succeeded in improving landscape functionality and integration without reducing mineral production or changing operations. Monitoring revealed localized erosion from poorly planned road runoff discharge and sporadic tunnel erosion, while sediment movement at the designed drainage network mirrored local fluvial dynamics.
Geomorphic-based mine restoration of clay quarries in Tortosa (Catalonia) was co-funded by the European Union's LIFE programme. The landform design was made with GeoFluv-Natural Regrade. Their building was performed with existing machinery pool and operators. The main constraint was the impossibility of setback regrading of pre-existing-benched highwalls. Progressive geomorphic mine restoration neither reduced mineral production nor changed the operations. The approach has resulted in higher landscape functionality and integration. Monitoring showed localised erosion due to poorly planned discharge of road runoff and sporadic tunnel erosion. Sediment movement at the designed drainage network is similar to the local fluvial dynamics.
