Introduction
Environmental Science degree, Ecosystem Restoration Master and PhD in Geology. Assistant Professor of Geomorphology, Geomorphic Reclamation, and landscape topographic technics and analysis. His research is focused on the geomorphic rehabilitation of areas affected by earth movements activities. He also studies the topographic stability and the water quality of such landscapes. His research outcomes are applied in national and international projects of mining, civil engineering and urban planning

Article
Landform instability of the abandoned Nuria kaolin mine, surrounding the Alto Tajo Natural Park in Spain, has caused frequent and severe environmental impacts due to deficient mining practices, environmental mismanagement and closure planning. Geomorphic instability has caused widespread soil erosion and elevated sediment yields with off-site effec...
Article
Controlling sediment produced by water erosion is the highest environmental challenge in steep, open pit sand mines located in erosive climates. Although restoration is impractical in active mine areas, sedimentation ponds are the Best Available Technique by the European Union to reduce sediment spillages from these environments. Few studies have d...
Article
Two abandoned kaolin mines, surrounding one of the most outstanding natural parks of Spain, the Alto Tajo, have caused frequent environmental impacts. Within these are unstable areas prone to extensive mass movements that influence off-site sediment dynamics over the fluvial system. A waste dump in the Nuria mine obstructing a stream in the center...
Article
This research describes a geomorphic-based process of mining reclamation carried out at the El Machorro mine (at the edge of the Alto Tajo Natural Park, East Central Spain) and its monitoring for five years (2012–2017). The GeoFluv™ method implemented by the Natural Regrade software has been used to design small watersheds as a mining reclamation t...
Article
This research documents the successful application of a novel holistic approach to return land degraded over thousands of years of use to full ecological function. The surroundings of the Somolinos hamlet in Central Spain illustrate a millennial history of land transformation and degradation by agrarian and extractive activities exacerbated at the...
Article
Full-text available
Conducting topographic surveys in active mines is challenging due ongoing operations and hazards, particularly in highwalls subject to constant and active mass movements (rock and earth falls, slides and flows). These vertical and long surfaces are the core of most mines, as the mineral feeding mining production originates there. They often lack ea...
Article
We report on channel morpho-texture and bedload transport in a natural, steep, sand-gravel ephemeral channel draining the small Poveda Gully watershed in the mining area of the Alto Tajo Natural Park, Spain. First-ever continuous bedload flux and texture monitoring in a transitional sand-gravel environment was undertaken by two independent Reid-typ...
Article
Mining is the largest producer of solid wastes which, when released to land or into waterways, can cause harmful environmental impacts. This is mostly due to fluvial erosion, which is highly increased in mountain areas, due to abrupt slopes. We have analysed this situation at a mountain watershed (192 ha), where steep mined sites and their waste du...
Article
Between 1875 and 1955 approximately 250,000 Mg yr− 1 of mercury-, arsenic-, and cyanide-contaminated mine tailings were discharged directly into the Ohinemuri River and its tributaries, in the Coromandel Region, North Island, New Zealand. A devastating flood on 14 January 1907 deposited large amounts of mine waste across the floodplain of the Ohine...

The Mazarrón district in southeast Spain was subjected to about a hundred years of intense mining activity for lead, silver, and zinc. Metallurgical operations during the late nineteenth century – early twentieth century ultimately led to significant land transformation. The most conspicuous wastes of this period consist of a chaotic piling of tail...
Conference Paper
During the last 5 years, a series of experiments have been carried out in the mining area of Alto Tajo Natural Park with the aim of understanding the hydrologic-sedimentary effects of mining activity over the fluvial system. Additionally, geomorphic restoration solutions have been adopted to reverse those effects. Through a “Before-After Control-Im...
Article
Mining is a human activity with considerable environmental impact. To evaluate such impacts, international laws require undertaking local studies based on direct sampling to establish baseline conditions of parameters modified by human activities. Mining takes place near the Alto Tajo Natural Park, where a suspended sediment concentration (SSC) bas...
Conference Paper
Full-text available
Chaotic pilling of old tailing deposits ―and modern' tailings resulting from froth flotation― are accumulated worldwide in different physiographic locations, mostly filling small valleys. Once abandoned, tailing deposits undergo severe erosion, resulting in a mosaic of erosional and sedimentary landforms developed upon and within them. Additionally...
Article
The San Cristóbal–Perules mining site in Mazarrón in southeast Spain was subjected to about a hundred years of intense mining activity for lead, silver, and zinc. Metallurgical operations (smelting, calcination, gravity concentration) carried out during the late nineteenth century–early twentieth century induced significant land transformation, and...
Conference Paper
This paper describes seven examples of geomorphic reclamation on mined lands of Spain, as solutions for complex environmental problems, by using the GeoFluv method through the Natural Regrade software Carlson). Of these seven examples, four of them have been partially or totally constructed. Each of them has its own particularities and contribution...
Article
Full-text available
Gullies are developed under different climatic conditions and lithologies; however, those formed on sands have been scarcely described. This paper reports the study of the Ribagorda sand gully, 2.57 ha in area (east-central Spain). The main objectives were to characterize and quantify its geomorphic dynamics and to trace its origin. We described th...
Conference Paper
The objectives for studying the Ribagorda sand gully (Upper Tagus Natural Park, Guadalajara) were to find out its origin and age and to quantify its current geomorphic activity. Historical records and maps were consulted to determine the land transformation. To quantify sediment yield, we monitored, for five years, the filling of the storage areas...
Conference Paper
The fluvial network of the Upper Tagus Natural Park (UTNP) (Guadalajara) is distinguished by the high quality of its aquatic ecosystems. Mined areas (mainly inactive) and gullies located at the buffer zone of the UTNP have been identified as a main source of sediments in this region, with potential ecological negative effects. Therefore, a monitori...
Conference Paper
Failures have been and are too common in spite of the significant development of mining reclamation techniques during the last decades. The most common cause of those failures is the lack of understanding of the long-term geomorphic stability of the reclaimed landforms. In this framework, an increasing number of cases and research initiatives are p...

En este artículo se describen los aspectos fundamentales de un Plan de Restauración. Se explican las actuaciones realizadas en el caso concreto de la cantera los Quebraderos de la Serrana (Noez, Toledo). Primero se realiza una reconstrucción geomorfológica, para después proponer un diseño de explotación y restauración que compatibiliza la obtención...

Project
Improving teaching of fluvial process, forms, and dynamics are the main topic of the project. The project uses a low cost (built by project members and students) fluvial scale model, digital photogrammetry (SfM), LiDAR data (terrestrial laser-scanner), and 3D printing. The project try to introduce students in main variables controlling fluvial plant-form; data acquisition; data processing in point-clouds and GIS software environment; and 3D printing techniques.
