“…The urban growth due to the mass tourism [21], the continuous construction of marinas and commercial ports, promenades and groynes had an extraordinary impact on the Mediterranean coasts [2,11,20]. Therefore, governments should provide solutions, such as beach nourishment for protection against erosion [13].…”

The historical evolution of sandy beaches on the coast of Alicante (Spain) has been analysed from aerial images from 1956 to 2019. The beach nourishments carried out in the 1990s to avoid coastal damages and to improve the touristic offer were studied. Shoreline evolution and beach surface has been obtained using GIS. The change of the sediment composition, from gravel to sand, due to the fills has caused a relevant imbalance. Beach nourishments failed its main aim of avoiding the shoreline erosion, causing environmental damages to the nearby Posidonia oceanica meadows.

“…Os dados que relacionam a intensidade pluviométrica de um local podem ser considerados modelos de valores de energia potencial disponível para transforma-se em energia cinética responsável pela erosividade da chuva (Acquaotta et al, 2018;Mioto e Silveira, 2019). Neste cenário, se pode afirmar que quanto maiores os valores de intensidade pluviométrica, maior a erosividade da chuva, na qual é possível criar uma escala de erosividade da chuva que retrate a influência do clima nos processos morfodinâmicos (Crepani et al, 2001;Oliveira e Selva, 2019).…”

“…Vale ressaltar, que as precipitações pluviométricas são bastante escassas e se concentram em um curto período para essa região e, geralmente, ocorrem na forma de chuvas torrenciais. Estas chuvas são a principal causa das perdas de solo no semiárido brasileiro, provocando mudanças na consistência do terreno e o assoreamento dos corpos hídricos superficiais (Mioto e Silveira, 2019;Tinôco et al, 2019).…”

“…A erosão é tão antiga quanto o planeta Terra, sendo geológica e procedente de fenômenos naturais que agem constantemente na superfície terrestre, como eventualidade natural do processo de remodelação do relevo, e estabelecendo um processo positivo para a formação do próprio solo (Ozsahin et al, 2018;Poesen, 2018). A ação antrópica quebra essa harmonia, rompendo o equilíbrio natural desse processo, e dando origem a erosão acelerada (singularizada apenas como erosão), fenômeno que gera grandes prejuízos à sociedade (Poesen, 2018;Efthimiou et al, 2020;Borrelli et al, 2021).…”

A degradação dos solos constitui um dos principais problemas da atualidade, sendo decorrente, na maioria das vezes das ações irresponsáveis do ser antrópico sobre os recursos naturais, nesse cenário, o geoprocessamento se apresenta como uma importante ferramenta de investigação, servindo de base para identificação dos níveis de degradação ambiental, bem como na classificação de terras e na elaboração de mapas cartográficos que auxiliem no planejamento público, e em novas pesquisas acadêmicas. Neste estudo, teve-se por objetivo avaliar a susceptibilidade à erosão hídrica na Bacia Hidrográfica do Rio Piancó, por meio de geotecnologias. Em síntese, a sequência dos procedimentos metodológicos utilizados nesta pesquisa foram: levantamento bibliográfico, criação de um banco de dados georreferenciados, atribuição de pesos as classes de susceptibilidade à erosão do solo, elaboração de mapas temáticos e geração de um mapa final de vulnerabilidade à erosão hídrica. A partir dos resultados, foi possível identificar áreas de incompatibilidade legal e averiguar que 66% da área de estudo apresentou grau de vulnerabilidade medianamente estável/vulnerável e que outros 19% da área enquadraram-se de moderadamente vulnerável a vulnerável, indicando assim, a necessidade da adoção de medidas mitigadoras a fim de reduzir a vulnerabilidade dos solos nesses locais. Por fim, pôde-se concluir, que o uso de geotecnologias associado a modelos empíricos é eficaz na classificação de vulnerabilidade à erosão hídrica. Analysis of Susceptibility to Water Erosion in a Hydrographic Basin on the Brazilian SemiaridA B S T R A C T Soil degradation is one of the main problems nowadays, being the result, in most cases, of the irresponsible actions of anthropic being on natural resources, in this context, geoprocessing presents itself as an important research tool, serving as a basis for identifying levels of environmental degradation, as well as in the classification of lands and in the elaboration of cartographic maps that assist in public planning and in new academic research. In this study, the objective was to evaluate the susceptibility to water erosion in the Piancó River Hydrographic Basin, through geotechnologies. The sequence of the methodological procedures used in this research were: creation of a georeferenced database, assigning weights to classes of susceptibility to soil erosion, thematic maps elaboration and generation of a final map of vulnerability to water erosion. From the results, it was possible to identify areas of legal incompatibility and ascertain that 66% of the study area had a moderately stable / vulnerable degree of vulnerability and that another 19% of the area classified themselves as moderately vulnerable to vulnerable, thus indicating the need the adoption of mitigation measures in order to reduce the vulnerability of soils in these places. Finally, it was concluded that the use of geotechnologies associated with empirical models is effective in classifying soil vulnerability to water erosion.Keywords: Environmental vulnerability.

“…The dry beach represents a buffer zone that absorbs, reflects and dissipates energy delivered by waves to the shore specially during storm events, protecting in this way the areas behind it from the impact of erosion and flooding [40] and, therefore, dry beach characteristics have to be taken into consideration in coastal sensitivity determination [41]. In addition, foredunes are one of the most relevant coastal ecosystems that work as natural defenses able to reduce flood sensitivity/vulnerability [42][43][44], as they often protect large sections of low-lying coasts against flooding during extreme storms [45][46][47]. Therefore their maintenance/emplacement has been considered as an effective coastal protection measure that is included among possible "Disaster Risk Reduction" (DRR) strategies in several European directives [43,[48][49][50][51].…”

Coastal environments are complex systems that are influenced by a combination of natural processes and human activities. Scientific interest in the effects of coastal erosion/accretion and climatic change-related processes greatly increased in recent decades due to the growing human development along coastal areas. This paper investigates the state and evolution of beach-dune systems for the 1977-2001 and 2001-2019 periods of the Mediterranean coast of Andalusia (Spain) using two different proxies: the dune toe line, which was used to track foredunes evolution, and the high-water line, which was used to assess shoreline evolution. Results showed a general erosional behavior of the studied beach-dune systems and identified cases where the main trend was altered through human interventions. In the 1977-2001 period, 54% of foredunes showed erosion, 24% accretion and 22% stability while and 34% of shorelines showed erosion, 40% accretion and 34% stability. In the 2001-2019 period, 42% of foredunes showed erosion, 28% accretion and 30% stability, and 40% of shorelines showed erosion, 34% accretion and 26% stability. Combining the evolution classes of each proxy (dune toe/shoreline) allows the behavior of both shoreline proxies to be assed together and provides insights additional to those derive from the use of a single proxy. In this regard, Erosion/Erosion (EE) was the most frequent behavior, with 25% and 27% in the first and second periods respectively, and Accretion/Accretion (AA), with 17% in both periods. Erosion of foredunes combined with stability or accretion of the shoreline (ES and EA) were the most common pairings in the first period, while stability of dunes combined with accretion of the shoreline (SA) and Stability/Stability (SS) dominated in the second period. The results obtained provide additional insights on the nature and drivers of coastal change that aid local coastal managers and administrations in understanding erosion processes. The method can be applied at other areas around the world where a similar data base is available.
