Simulating the evolution of stakes on Réunion Island in a context of coastal risk
2017
This paper describes a model and a simulation tool which aim at help decision-makers and planners dealing with their processes for territorial prospective analysis. It is based on a practical study case, located on Réunion Island (France). This study has been carried out within the VULNERARE research program, granted by Foundation de France: one of VULNERARE aims is to estimate and assess Réunion's vulnerability in the next 30 years, in relation to coastal risk. This paper is specifically focussing on the dynamics and the future state of two important stakes: population and urban structures. Will urban development of littoral zones increase? How fast and which type of population will be exp…
Isolation and characterization of hydrocarbonoclastic bacteria from Algerian coast
2017
Backgrounds The contamination of marine environments by hydrocarbons represents a global concern with consequences on ecosystems and human health. The removal of HC by physical and/or chemical methods is expensive and disrespectful of the environment. The use of HC degrading bacteria is a good alternative for environmental remediation (bioremediation). Objectives The Algerian coastline is exposed to several types of pollutions, including hydrocarbons. The aim was to explore the bioremediation potential of its contaminated harbors for the first time. Methods To identify the hydrocarbon degrading bacteria seawater samples were collected in Sidi fredj harbor (Algeria) and used to enrichment cu…
Palermo. Una città, una visione
2019
The city of Palermo is open towards South West. It is from that directions that all the connections to Europe arrive. Yet the importance of that area has been rarely acknowledged. Marcello Panzarella, architect and professor of architecture has carefully studied that area. Students'work and his own research work span more than a decade. Its outcome is contained in the book, which is also a real urban project for Palermo
Global Coastal Permeability database (GCPdb)
2023
The Global Coastal Permeability Database contains both the input and output data of the Global Coastal Permeability Model developed by Tschaikowski et al. (2023) and available at DOI: 10.5281/zenodo.7845568. The model is implemented in R and calculates the coastal permeability for each shoreline segment of the global shoreline vector created by Sayre et al. (2019) with a 30-meter resolution and covering a spatial extent of 180.0°W to 180.0°E longitude and 60.8°S to 83.7°N latitude. The coastline is separated into three sections (A: coastal aquifer section, B: shoreline section, C: shallow section), and permeability values and ranges are provided for each section. Permeability values were de…
Using optical satellite and aerial imagery for automatic coastline mapping
2020
The continuous availability and rapid accessibility to multispectral data from satellite platforms within the Copernicus Programme represents a great opportunity for users in different fields of applications as: Agriculture, observation of coastal zones, monitoring land cover change. The aim of this paper is to identify a suitable method to map coastline using Sentinel-2 optical satellite image. The method provides the use of two indexes developed in remote sensing field for water environment: NDWI (Normalized difference water index) and MNDWI (Modified Normalized difference water index). Starting from the construction of maps of these indexes and, identifying appropriate threshold values, …
An Approach for the Validation of a Coastal Erosion Vulnerability Index: An Application in Sicily
2022
In recent decades, coastal erosion phenomena have increased due to climate change. The increased frequency and intensity of extreme events and the poor sediment supply by anthropized river basins (dams, river weirs, culverts, etc.) have a crucial role in coastal erosion. Therefore, an integrated analysis of coastal erosion is crucial to produce detailed and accurate coastal erosion vulnerability information to support mitigation strategies. This research aimed to assess the erosion vulnerability of the Sicilian coast, also including a validation procedure of the obtained scenario. The coastal vulnerability was computed by means of the CeVI (Coastal Erosion Vulnerability Index) approach, whi…
“Promenade along the coast: Paul Nash and Dave McKean revisit Dymchurch”
2019
This paper examines the specificity of the coastline as a natural, cultural and medial boundary and interface. It focuses on how the motif of the coastline is depicted and remediated in the works of English artists Paul Nash and Dave McKean: between 1919 and 1925, as he was coming to terms with the aftermath of the First World War, Nash created a series of pictures depicting Dymchurch on the coast of Kent in England; McKean’s 2016 commemorative graphic novel Black Dog: The Dreams of Paul Nash is a biographical exploration of Nash’s youth, of his experience of the war and of his recovery in the immediate post-war period. The interplay between memories of the trenches and the landscape of the…
Bases metodológicas para el uso de la modelización en la enseñanza y comprensión de la dinámica litoral
2017
[EN] This paper proposes the use of modelling to improve the understanding of certain coastal environmentalproblems. In particular the methodological basis that was used to build a consensus teaching model, in-cluding environmental and human factors that determine the dynamics of coastal sediments, is included.The development of the consensus model had the collaboration of experts in coastal sedimentology andecosystems as well as teachers of di erent educational levels (from Primary to University), which helpedselect the ages to which the modelling could be applied, helping also in developing the graphical model thatwould be the base for a future educational intervention
