Effects of stone-made wind shelter structures over an arid nebkha foredune.

Beach users often use a range of strategies to shelter from the wind and blown sand. This involves building structures made of stacking stones. Different from other portable wind blockers, stone-made wind shelters can remain in the landscape for a long time.

Environmental variables affecting an arid coastal nebkha.

Foredunes in arid coastal dune systems comprise nebkhas, which originate by interactions between vegetation and aeolian sedimentation. While continuous foredunes in temperate climates have been widely studied, knowledge of interactions between biotic and abiotic drivers in foredunes formed by nebkha is still scarce. With the aim of exploring variables affecting arid foredunes, a range of morphological, sedimentological, and vegetation characteristics were measured on a single nebkha formed by a Traganum moquinii plant located in the foredune of Caleta de Famara beach (Lanzarote, Canary Islands).

Assessing the scenic quality of transgressive dune systems on volcanic islands. The case of Corralejo (Fuerteventura island, Spain).

The formation of transgressive aeolian sedimentary systems on hot-spot volcanic islands results in globally singular conditions. The natural attractions and landscape features of these spaces can result in the concentration of urban-tourist developments in their surroundings, altering their physical integrity and their ecological and scenic functionality. This has been the case of the Corralejo dunefield in Fuerteventura (Canary Islands, Spain), where the strong pressure exerted by tourism is endangering the area's natural and landscape resources.

Nebkha development and sediment supply.

This study examines the role of sediment supply in controlling the formation and the spatial patterns of nebkha, numbers and sizes, present in foredunes fronting coastal dunefields of the arid northwest African and the Canary Islands coasts. Sediment supply is estimated qualitatively and quantitatively by various measures, and the number and size of nebkhas are obtained on a range of beach-dune systems. In the case of the Canary Islands, LiDAR data and orthophotos with high spatial resolution (0.

Spatiotemporal analysis of the impact of artificial beach structures on biogeomorphological processes in an arid beach-dune system.

The research hypothesis considered in this study is that decisions adopted on beach use and management in arid environments can result in significant changes in the biogeomorphological processes of the beach-dune system of which it forms part. Different information sources and geographical information systems were used to make a spatiotemporal analysis of possible correlations between the presence of beach equipment, services and uses in the backshore area of an arid beach-dune system, such as the beach named Playa del Inglés (Gran Canaria island, Spain) and environmental changes detected in the same area. The period considered in the study covers from 1961 (before the development of the mass tourism on the island) to 2018.

Decadal monitoring of Traganum moquinii's role on foredune morphology of an human impacted arid dunefield.

Foredunes in arid zones have been little studied, being significantly different than tropical and temperate foredunes. In the case of the foredune of the arid Canary Islands' dune systems, Traganum moquinii is the predominant plant species, forms nebkhas and nebkhas fields, and acts as a structuring element in the dune field. In this work, the eco-anthropogenic evolution of the foredune surface, and the morphology and distribution of Traganum moquinii species in the Maspalomas dunefield (Gran Canaria, Canary Islands) are analysed, to understand the role that this plant species plays on the foredune's geomorphology and on the biogeomorphological processes altered by human actions.

A DIY Low-Cost Wireless Wind Data Acquisition System Used to Study an Arid Coastal Foredune.

Environmental studies on coastal dune systems are faced with a considerable cost barrier due to the cost of the instrumentation and sensory equipment required for data collection. These systems play an important role in coastal areas as a protection against erosion and as providers of stability to coastal sedimentary deposits. The DIY () approach to data acquisition can reduce the cost of these environmental studies.

An historical ecological assessment of land-use evolution and observed landscape change in an arid aeolian sedimentary system.

Coastal areas worldwide are undergoing major changes and degradation due to a set of combined natural and anthropogenic stressors. In arid aeolian sedimentary systems these changes can be even more acute given their sensitivity to perturbances in landscape dynamics. While in many such areas recent (20 year) observations have been made regarding measurable differences in dune coverage and stability, few studies have assessed and quantified the long-term relationships of transitioning exploitation and land-use changes in order to fully evaluate their importance.

Climate as a control on foredune mode in Southern Australia.

Foredunes are formed by aeolian sand deposition in vegetation on the backshore of beaches. In this paper, the foredune mode (nebkha, discontinuous foredune, and continuous foredune), and transgressive dunefield development is studied along the Great Australian Bight (GAB), 2668 km of coastline. Orthophotos are used to classify the foredune mode, coastal landforms and the vegetation, through geographic information systems (GIS), with fieldwork support.

Beach vegetation as an indicator of human impacts in arid environments: Environmental conditions and landscape perception in the Canary Islands.

Human occupancy of beaches is an important cause of environmental and landscape transformations, some of which are identifiable through vegetation analysis. Commonly, arboreal vegetation has been socially perceived in a positive way, as it contributes to the creation of environments appreciated as beautiful and natural. This type of vegetation has been recreated in urban coastal areas worldwide, including those located in arid environments where it is not always common or endemic to these areas.

Measuring geomorphological vulnerability on beaches using a set of indicators (GVI): A tool for management.

A system of indicators has been developed to evaluate beach geomorphological vulnerability (GVI) through: intrinsic susceptibility, the agents that model them, and their ability to remain stable over time. The method is applied to 34 beaches on the island of Gran Canaria (Spain) that experience different levels and conditions of human occupation, marine incidence, landforms and sediments, and spatial evolution that have been recorded since 1960. In contrast with other studies, the analysis of these dimensions (and their relationships) allows a diagnosis of the geomorphology of the beaches with an integrated approach.
