The Coastal Risk Index is
the platform for assessing
coastal resilience
The Coastal Risk Index – the CRI – harnesses the power of data to enable financial institutions, investors, insurers, and policymakers to better assess coastal risk and improve decision-making in the climate crisis.
Better Data
Better Data
The CRI provides the foundation for better understanding coastal risks, enabling more informed decisions about building resilience in coastal communities. It goes beyond physical flood risk and economics to include social drivers and incorporate the crucial role of nature.
The CRI is an open-source platform providing a detailed set of global flood maps, using hydrodynamic models, to understand current and future coastal flood risk and the flood reduction benefits of natural habitats. Social vulnerability data highlights where reefs and mangroves are critical to reducing risk for climate vulnerable coastal communities.

The CRI is designed to inform financial institutions, insurers, policymakers, and other decision-makers about climate risks and resilience strategies for coastal areas. This platform enables communities to be more resilient while protecting and restoring nature.

The CRI provides data on the benefits of resilient ecosystems to climate vulnerable coastal communities. This data supports decision-makers in integrating Nature-based Solutions into tools that minimise risk, build resilient communities, and restore ecosystems.
The Future of
Coastal
Flooding
The Coastal Risk Index provides a detailed way to assess coastal flooding in the context of climate change, modelling flood hazard and storm surge in current conditions and in possible future climate scenarios.
The following map shows the CRI’s data on the impact of losing mangrove protection (on the left), as the extent and depth of flooding increases if mangroves are not present (on the right). By quantifying the value of reef and mangrove ecosystems for their flood resilience benefits, the Index can help catalyse their restoration and protection across the world.
These visualisations map the future with (left) and without (right) mangroves present to demonstrate the importance of coastal habitats for reducing risks. Taller and darker columns indicate higher flood depths. Swipe using the middle arrows to compare the two scenarios for Naga City, Philippines and Cape Coral, Florida.

About
This Platform
Using models and data developed by IHE Delft and University of California Santa Cruz, the CRI demonstrates flooding at 90 metres resolution in different scenarios and intensities. Explore the initial maps to understand where communities are most at risk, now and into the future and where mangroves and coral reefs play a crucial role in reducing economic, social and biodiversity impacts.

User Benefits
The CRI is open to all. Users can view flood hazard maps for any coastal area and understand the avoided costs nature provides to both people and assets. Users can also examine areas of high social vulnerability and where investing in coastal Nature-based Solutions plays a role in protecting communities.
Financial institutions, insurers, governments, and banks can leverage the data and insights on this platform for policy and product development.
-
Insurers
Integrate ecosystems in risk models to develop new products and more accurate pricing while working with clients to manage their risks.
-
Financial Institutions
Understand how ecosystem health affects investments in the long-term, map future liabilities, and develop innovative finance solutions that incorporate nature.
-
Governments & Policymakers
Assess exposure of their communities and identify opportunities for significant restoration benefits to target resources and protect people, infrastructure, and society.
-
Development
BanksManage long-term risks to investment portfolios, target development assistance towards Nature-based Solutions, and gain a clearer understanding of economic benefits of coastal habitats.
Features
The CRI is the platform for understanding coastal resilience. Taking these initial maps a step further, the aim is to develop a full data platform that allows users to interact with the underlying data, to dive deeper into insights on coastal flooding and the role of Nature-based Solutions. These concepts showcase the future direction of this interactive platform. What is shown on these screens is not interactive, but illustrative of the features and functionality the full CRI aims to develop. The final platform may differ from what is shown here.
