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...
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...
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...
In the half-dozen decades following World War II, Earth's human population tripled and the global gross domestic product increased nine fold. The disparity in these figures reflects an unsustainable increase in the rate of consumption of Earth's natural resources—an increase that has been dubbed The Great Acceleration. Humans are using renewable re...
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 hig...
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...
Fluvial geomorphic approaches for reclamation landform design have been applied since 2000, mostly in mined lands, as an alternative to conventional landform design methods. Those approaches aim to reconstruct mature landforms and drainage networks that would develop within a natural catchment, after thousands of years of work performed by geomorph...
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 recogn...
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...

Computer modelling and design tools can assist in environmental management. In particular, post-mining landscapes with large volumes of materials require shaping for optimal erosional stability and ecological and visual integration into the surrounding undisturbed landscape. This paper evaluates the complementary capabilities of landscape evolution...
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...
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...
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...

The Sierra of Ayllon in Central Spain has a rich heritage from both the architectonic and geological perspectives. On one hand, the low lands flanking the northern side of the sierra in the Segovia Province host the so-called red hamlets and black hamlets (pueblos rojos-pueblos negros). The red and black terms derive from the traditional local buil...
Badlands and gullied areas are among those geomorphic environments with the highest erosion rates worldwide. Nevertheless, records of their evolution and their relations with anthropogenic land transformation are scarcer. Here we combine historical data with aerial photographs and tree-ring records to reconstruct the evolution of a badland in a Med...

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...
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...
In the Comarca de Molina-Alto Tajo Geopark and in the Buffer Zone of Protection of the Alto Tajo Natural Park (ATNP) kaolin mining is being developed since 1965, currently existing active mines (with measures for erosion and sedimentation control) and inactive (without control measures). The sediment emission from the latter to the hydrological net...
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...

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...
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...
This paper was developed from an original experimental design that aimed to study plant community assembly in a roadcut under mediterranean conditions. We investigated the effect of different conventional treatments in attenuating environmental filters constraining secondary succession in man-made ecosystems.
QuestionsHow does the response to environmental filters change across the life cycle of pioneer plants through the early process of community assembly? Is there a threshold at any of the life-history stages during roadcut primary colonization?LocationA very steep, sun-exposed, low-fertility and low water retention roadcut in a Mediterranean contine...
Summary This paper reports on bedload flux and texture monitored in a natural, steep, sandy ephemeral channel draining a small gullied sandy watershed, the Barranca de los Pinos (1.32 ha), Spain. Bedload flux was continuously monitored with two independent Reid-type slot samplers; bedload texture was determined from the sediment collected in the sa...
Mining reclamation tries to reduce environmental impacts, including accelerated runoff, erosion and sediment load in the nearby fluvial networks and their ecosystems. This study compares the effects of topography and surface soil cover on erosion on man-made slopes coming from surface mining reclamation in Central Spain. Two topographic profiles, l...

In recent decades, changes that human activities have wrought in Earth’s life support system have worried many people. The human population has doubled in the past 40 years and is projected to increase by the same amount again in the next 40. The expansion of infrastructure and agriculture necessitated by this population growth has quickened the pa...
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...
Póster presentado en la XII Reunión Nacional de Geomorfología, Santander 2010-1012
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...
This paper describes a methodological procedure for organizing geoheritage information, aimed at geoconservation and geotourism planning and management in protected areas. This method has been applied in a real-life process to declare the Covalagua and Las Tuerces sites as protected areas in the province of Palencia, in Northern Spain. Although the...
Soil and vegetation are interacting factors controlling erosion. Soil degradation processes may affect the normal tree and shrub development and inversely, vegetation can modulate the velocity and intensity of soil development or denudation. A dendrogeomorphological approach can be used to study these interactions, allowing to obtain a date and est...
The assessment of gully erosion poses a great challenge because of the complexity and connectivity of the geomorphic processes involved. This study focuses on the quantification of sheet erosion rates in a set of slope gullies located on the northern piedmont of the Guadarrama Mountains (Spanish Central System). In order to delineate accurately the...
Gullies developed on sandy lithologies are scarce and few studies have been reported on these landscapes. This paper presents an approach to study such singular landforms. The studied gullies appear on the slopes of a group of mesas and cuestas of Upper Cretaceous sediments located in the Northern piedmont of the Guadarrama Mountains, Spain.Landfor...

The assessment of gully erosion is a challenge due to the complexity and connectivity of the geomorphic processes involved. In general, eroded materials by weathering processes are transported from slopes to gully bottoms by mean different hydric processes. Next, fluvial processes yield these sediments to the nearby fluvial networks. As consequence...
A mining reclamation model based on geomorphic principles, called ‘catchments on slopes’, is described. The model establishes an expert handling of open-cast mining runoff by means of a desing which splits off the slope landforms in small catchments. Aditionally, criteria for the handling of superficial deposits and soils are integrated. A clay slo...
