Coastal storm surge risk analysis

Coastal storm surge risk analysis is a comprehensive framework that combines scientific, technical, and socio-economic analyses to assess and manage the risks associated with storm surges.

The outcomes of coastal storm surge risk analysis are critical for informing a wide range of policy and planning decisions. These include designing and implementing coastal defense structures, developing land-use policies to limit development in high-risk areas, enhancing building codes and standards, planning evacuation routes and strategies, and setting insurance premiums. Moreover, it supports the development of comprehensive disaster risk management and climate adaptation plans, aiming to reduce the vulnerability of coastal communities and increase their resilience to storm surge and other climate-related hazards.

GIS-based layered mapping for storm surge analysis

GIS tools are essential for mapping and analyzing the spatial relationship between storm surge hazards and coastal assets, facilitating exposure and vulnerability assessments. We can use GIS tools to overlay storm surge forecasts with maps of coastal areas, highlighting vulnerable locations, critical infrastructure, and population densities to assess potential impacts.

The TranzAI platform provides a layered mapping system that enables detailed, multi-layered assessments of impacts to critical infrastructure, public health systems, and other key assets. Each layer represents a different aspect of the coastal zone, such as road networks, public health facilities, residential areas, critical infrastructure (e.g., power plants, water treatment facilities), and ecological zones. The system allows users to toggle between layers or view multiple layers simultaneously for a comprehensive analysis.

Critical infrastructure risk assessment

Critical infrastructure risk assessment is the cornerstone of storm surge risk analysis and, more broadly, climate risk analysis due to the fundamental role that infrastructure plays in the functioning of the society, economic stability and public safety. This assessment is essential due to the interconnectivity of infrastructure systems and the cascading effects that can result from their failure during climate-related events.

The TranzAI platform provides a dedicated infrastructure data management ontology and direct access to data sources that provide detailed infrastructure geometry and location. This powerful combination enables users to achieve unprecedented levels of accuracy and insight in their analysis of infrastructure vulnerabilities and the potential impacts of climate events. By leveraging this ontology, we ensure that data is structured and categorized in a way that reflects the complex interdependencies and characteristics of different infrastructure components. This structured approach facilitates more nuanced risk assessments, predictive modeling, and scenario analysis.

Scenario planning

Developing scenarios based on different combinations of sea-level rise and socio-economic conditions helps in understanding potential future risks and testing the effectiveness of mitigation strategies.

The TranzAI platform approach to managing scenarios through parameterized queries offers a sophisticated and dynamic method for analyzing the impacts of climate events under various future conditions. This system allows users to explore a wide range of scenarios by adjusting variables related to the intensity of climate events and the vulnerability of infrastructure.


The TranzAI platform provides a comprehensive coastal storm surge risk analysis framework that combines scientific, engineering, and socio-economic analyses to assess and manage storm surge risks. It plays a critical role in improving coastal resilience by informing evidence-based decision making and promoting sustainable coastal management practices.
