Coastal Flooding Resilience

Global Challenge

Plan for and adapt to more frequent, widespread and severe coastal flooding

Coastal flooding is a growing, global concern

Rapidly growing cities are making more people vulnerable to rising sea levels.

Today, approximately 3 billion people — roughly half of the world’s population — live within 200 kilometers of a coastline. By 2025, that figure is likely to double.

Coastal development may destroy natural barriers such as islands and wetlands, can promote erosion and flooding, and often positions more buildings and people in the path of potential destruction.

Proper coastal flooding resilience planning can help improve the long-term sustainability of coastal communities.

According to The Global Risks Report 2019, published by the World Economic Forum, the most frequently cited risk interconnection was the pairing of ‘failure of climate-change mitigation and adaptation’ and ‘extreme weather events.’

MIKE Powered by DHI’s coastal flooding technology offers the greatest ability to not only UNDERSTAND VULNERABILITIES but to DEVELOP REAL SOLUTIONS to help protect a community from flood danger.

Here are the ways we can help:


Visualise the potential magnitude of flood danger to your community with user-friendly online tools to help launch climate adaptation strategy planning


Tap into a variety of data portals for reliable environmental data on water levels, currents, wind and waves to better understand local conditions for proactive flood risk management planning


Pick and choose from a curated selection of eight software modules to analyse, model and simulate flood risks unique to your community to design appropriate flood defences


Convert the knowledge gained from your models into actionable information through the creation of flood forecasting and warning systems to protect and alert the community of impending flooding and real-time inundation mapping for disaster relief


Adapt to changing climate conditions by optimising the control of flood defenses with a real-time operational control system or making informed recommendations on retreat

A mix of coastal adaptation measures can potentially reduce the magnitude of coastal impacts

Futureproof your investment with a more holistic solution that pushes the limits of decision support

Take a robust, multi-layered approach to coastal adaptation

Collect and Collate Data

Gather data on Metocean conditions

Map the coastline

Use satellite derived bathymetry to build a picture of the historical evolution of the coastline

Build a Model

Reveal hydrodynamic and morphological condition change

Identify vulnerable areas and establish coastal flood risk management plans

Understand how to protect your beaches from coastal erosion ensuring the integrity of natural buffering systems

Build a real-time system

Make robust flood warning accounting for all important forcings such as tides, storm surge, and wind waves

Produce highly actionable information for emergency situations and disaster relief e.g. high fidelity flood maps, probability of contracting illness from water borne diseases

As sea levels rise and urban vulnerabilities increase, mainstream investment in adaptation and resilience will follow.

There are many coastal flooding tools that can help evaluate flood risk. However, understanding risk in itself is just the beginning.

The amount of actionable information gained from layering MIKE Powered by DHI’s complementary tools and modelling software enables true adaptation to be achieved.

Adapt based on real-time data

Optimise the operation of your flood control defenses on the fly

Operate urban infrastructure to protect from saltwater intrusion

Auto-calibrate water levels against live satellite imagery to more accurately predict the scale of potential flooding
