Multi-Hazard WebGIS Platform for Coastal Regions

Abstract

The combined action of waves, surges and tides can cause flooding, erosion and dune and structure overtopping in many coastal regions. Addressing emergency and risk management in these areas require a combination of targeted campaigns and real-time data that measure all phenomena at stake and can be used to develop comprehensive monitoring platforms. These monitoring platforms can support the development of prediction tools that address all hazards in an integrated way. Herein, we present a methodology focused on multi-hazard coastal alert and risk, and its implementation in a tailored WebGIS platform. The MOSAIC platform offers a one-stop-shop capacity to access in-situ and remote sensing data, and hydrodynamic and morphodynamic predictions, supported by numerical models: SCHISM and XBeach. Information is structured on a local observatory scale, with regional forcings available for the correct interpretation of local hazards effects. This implementation can be further applied and extended to other coastal zones. The MOSAIC platform also provides access to a detailed database of past hazardous events, organized along several risk indicators, for the western coast of Portugal. The combination of features in the platform provides a unique repository of hazard information to support end-users for both emergency and long term risk planning actions.

Comprehensive Analysis of the Use of Web-GIS for Natural Hazard Management: A Systematic Review

“…Integrating remote sensing with machine learning techniques has been employed to monitor natural hazards in coastal areas [53]. Platforms like the MOSAIC [54] utilise predictive models such as SCHISM and XBeach to interpret local coastal hazards effectively. Additionally, modelling soil erosion in catchments showcases the potential of these technologies in enhancing soil-related hazard risk assessments [55].…”

Geo-Informatics for the Future: A Systematic Literature Review on the Role of WebGIS in Infrastructure Planning and Development

“…Specific initiatives and immediate information that assess all relevant phenomena and may be utilized to create thorough monitoring platforms are needed to address catastrophe and risk mitigation in these areas. In Rocha et al's study [29], the WebGIS system's capabilities and features were created with a focus on the needs of future users, and its infrastructure was created using open-source and free applications for GISs in line with the Open Geospatial Consortium and the European legislation INSPIRE. The created WebGIS enables multi-temporal and multiple-sized analysis to assess and track saltwater quality, enabling local authorities to schedule the necessary corrective steps.…”

“…These surveillance systems can aid in the creation of forecasting algorithms that take into account all dangers together. In the article, the authors provide a technique for assessing multi-hazard coastal warning and risk and how it may be applied to a specific WebGIS platform [29].…”

Current and Future Multirisk Analysis in Climate Change Scenarios with Riskcoast WebGIS

“…According to Forzieri et al [2], the study of multiple hazards poses two major challenges: hazards are not directly comparable, as their processes and description metrics differ, and hazards can interact, triggering cascading effects and coupled dynamics. The significance of examining multiple hazards is especially pronounced in coastal regions, as they are exacerbated by climate change [9,10]. These areas are particularly exposed and susceptible to climate-related threats.…”
