Item Geomorphic landscape design integrated with progressive mine restoration in clay quarries of Catalonia(International Journal of Mining, Reclamation and Environment, 2021) Martín Duque, José Francisco; Tejedor, M.; Martín Moreno, Cristina; Nicolau Ibarra, José Manuel; Sanz Santos, Miguel Ángel; Sánchez Donoso, Ramón; Gómez Díaz, José M.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.Item Mining rehabilitation – Using geomorphology to engineer ecologically sustainable landscapes for highly disturbed lands(Ecological Engineering, 2020) Hancock, G.R.; Martín Duque, José Francisco; Willgoose, G.R.Mining is essential to the human economy and has been conducted for millennia. In the past ~60 years, the scale of disturbance created by mining has grown larger in response to economic demands and technology capacity. However the scale of disturbance from mining is dwarfed by that of urban expansion and agriculture. Nevertheless, it is well recognised that mine sites have radically disturbed abiotic and biotic system components that, post-mining need to restore new land uses and ecosystem goods and services. In many cases, such aims demand a geomorphic integration with the surrounding undisturbed landscape. Erosional stability based on geomorphic principles is the first and most important part of the process. Without erosional stability, vegetation will be difficult to establish and maintain and soil and nutrients will be lost from the site. In this review we outline this process and methods by which a geomorphic and integrative landscape can be established. We also examine the issue of establishing a self-sustaining landscape that is similar to that of the prior undisturbed landscape. Here we argue that this is not possible in almost all situations, however the development of a new and ecologically successful, albeit different landscape is. The community needs to accept that mining, like agriculture, is essential to the modern economy and that a past landscape cannot be replaced with the same, but a new, functional and productive one can be developed. However, the ability to do this and ensure long-term ecological sustainability is questionable for many sites and considerable effort needs to be made to develop the technology to ensure that this will occur. We outline a way forward, based on geomorphic design and modelling.Item Geomorphic-based mine rehabilitation coupled with AMD chemical stabilisation in sulphide-rich ore deposits and soils: insights from a pioneering intervention at the Lousal mine, Iberian pyrite Belt(International Journal of Mining, Reclamation and Environment, 2023) Sánchez Donoso, Ramón; Martins, Mónica; Tejedor Palomino, María; Esbrí Víctor, José María; Lillo Ramos, Francisco Javier; Pereira, Ana Margarida; Pinto, Álvaro Manuel; Relvas, Jorge Manuel; Martín Duque, José FranciscoThe Lousal mine rehabilitation project proactively planned strategic milestones around key local geomorphic landforms and geochemical characteristics. GeoFluv™ method was used to design a rehabilitation topography mimicking natural landforms, on which a built-up soil cover with chemical buffering capabilities and open limestone channels were implemented across the intervention areas. Once these landform restoration works were completed, positive effects are observed in March 2022, with the native vegetation cover (the third main component of the restoration plan) established in most of the recovered area and a visible water quality improvement to the AMD treatment system water. Potentially Toxic Elements (PTEs) concentrations have reduced significantly after the reclamation actions, especially Fe (404 to 34 mg L−1), Zn (65.7 to 15.8 mg L−1) and Cd (122 to 0.8 µg L−1) concentrations. Minor problems detected have been processes of rill erosion associated with the inflow of adjacent watersheds, and the creation of ephemeral reducing conditions resulting from the leaching of the organic amendment of the topsoil. The Lousal mine reclamation project is the first built example in Europe where the concept of geomorphic reclamation has been combined with geochemical remediation in an area with intense acid mine drainage formation. Detailed monitoring of this project’s restorative progression throughout 2024 and beyond, should offer learning opportunities and innovations which will benefit future rehabilitation projects, with comparable underlying features.Item Geomorphic rehabilitation in Europe: recognition as best available technology and its role in LIFE projects(2019) Martín Duque, José Francisco; Tejedor, M.; Martín Moreno, Cristina; Nicolau Ibarra, José Manuel; Zapico Alonso, Ignacio; Fourie, A. B.; Tibbett, M.Geomorphic rehabilitation ([GR], also known as geomorphic reclamation or geomorphic restoration) is a general term to describe alternative methods and procedures to conventional mine rehabilitation. The main aim of GR is to replicate ‘natural’ landforms for the new conditions after mining and to restore functionality and diversity of ecosystems at degraded sites. The correct application of the GR technique ensures visual integration with surrounding landscapes. Although GR is a broad term, referring to any geomorphic restoration of land, GR is often synonymous with fluvial GR, mostly following the GeoFluvTM-Natural Regrade method. This paper describes how and why the application of GR through GeoFluv-Natural Regrade in Spain since 2009 has attracted formal recognition by the European Commission (EC) of the European Union (EU) as one, among others, of a catalogue of best available techniques (BATs) for the management of waste from extractive industries, in accordance with the European Directive 2006/21/EC. GR has been recognised as BAT at the EU for multiple reasons, including mine site monitoring results that demonstrate increased physical stability with minimised erosion from stormwater and snowmelt runoff; natural hydrological function being established; the variability within the formed landform promotes ecological diversity for vegetation and wildlife communities; construction and short and long-term maintenance and repair costs are minimised; and visual impact of the mined landscape is reduced. This paper describes also the role of GeoFluv-Natural Regrade GR in the L’Instrument Financier pour l’Environnement (LIFE) program, which is the EU’s most important funding instrument addressing environment and climate action. A focus is provided on the LIFE TECMINE project, described in detail, since it is the most recent and complete GeoFluv-Natural Regrade example in Europe. The TECMINE project is a geomorphic-based ecological restoration project in the Valencia province, within the Iberian Mountain Range and where conventional mine rehabilitation practice, based on gradient terraces, shows general and widespread failure. The demonstration project is fostered by the Administration of the Valencia Region, which seeks to test innovative techniques (GR, micro-catchments, soil amendments and new protocols of revegetation) for mine rehabilitation, promote improved practices and disseminate the best practice output through their development and analysis. Testing GR is the main focus of the project. The application of GR at the TECMINE project included (a) finding ‘natural’ and ‘stable’ landforms and landscapes to be used as reference or analogues for replication in GR, although difficult, was possible due to ancestral land transformation; (b) the steep terrain, characteristic of the Iberian Range, challenged the formation of GR GeoFluv-Natural Regrade designs, but the project demonstrated that they can be implemented in that mountain setting; (b) the mining company reported similar cost estimations for this alternative GR rehabilitation (as-built) as that for a conventional restoration design (projected); (c) a holistic approach to GR, not dealing only with topography, allowed the identification and use of limestone colluvium as an adequate growth media for initiating soil development; this solution not used before for rehabilitation in this region provided a clear and advanced contribution from the project.
