Web-Based Platforms for Landslide Risk Mitigation: The State of the Art

Abstract

Web-based platforms (WBPs) are online spaces where the user can interrogate and analyze data series gathered in quasi-real time from monitoring network/s. These online tools are increasingly used by government agencies, local authorities, contractors, and researchers for visualization, management, control, and analysis of monitoring data. In the risk mitigation framework, WBPs must incorporate specific tools and functions to be integral to non-structural mitigation activities. This is particularly important for the mitigation of landslide-related hazards, that sometimes are challenging to address with structural solutions. The state-of-the-art paper considers the evolution of WBPs for risk mitigation from a pioneering research topic of a decade ago to the current applications that are sometimes comprised within commercial packages. First, we describe what nowadays represents the WBP requirements regarding usability and data visualization for proper data communication. Next, tools for data management and solution regarding interoperability and data analysis are discussed. Lastly, considerations on data filtering in the context of alert and alarm triggering are presented. To be a reasonable alternative to structural mitigation works, non-structural solutions such as monitoring for alarm triggering or early warning must be dependable and stable. We have synthesized the fundamental requirements of monitoring networks devoted to risk mitigation with the expression “5 Rs”: robustness, redundancy, reliability, resilience, and responsiveness.
