Solutions to Global Challenges

Empowering Coastal Resilience Planning Through Modelling

Benefit from prevention planning rather than crisis management

The issue

Many of us have chosen to live in low-elevation coastal zones putting ourselves at risk for the effects of flooding and coastal erosion. Despite the well-known challenges related to climate change, we continue to do so in rapidly growing coastal cities. This is a shared concern for coastal communities around the world – however, it is not too late to take action.

Why it matters

While coastal hazards are luring in the horizon, the devastating impact of these disasters can be prevented. Soft and hard coastal protection acts as a line of defense. As such, continuous and innovative upgrades are necessary to respond to rising challenges. Coastal resilience adaptation planning helps communities adapt and improve long-term sustainability against loss of lives and properties.

How we can help

Through advanced software technology, DHI strives to share our understanding of complex physics to serve coastal communities trying to adapt worldwide. Digital twins of coastal environmental settings can support you in mitigating coastline instability and flooding. Partner with DHI and de-risk the challenges of living in coastal areas.

Integrated solutions

Shoreline management decisions must be based on a sound understanding of complex natural processes. At DHI, we incorporate the latest scientific and technological advances into the building of custom solutions to help solve coastal instability and flooding related challenges.

Investigation of natural coastal protection schemes

Natural forces continuously reshape the coastline. Here at DHI, we promote soft engineering as an effective coastal protection strategy. By harmonising marine infrastructure with nature, we can help you design unique artificial coastal elements such as beaches, headlands, cliffs and lagoon environments. Explore our free Shoreline Management Guidelines eBook, which explains complex coastal phenomena in an easy-to-read manner to further support your shoreline management and waterfront development schemes in achieving sustainability and adaptability to climate changes.

Ensurance of realistic coastal design schemes during early planning

The early creative stages of conceptual architecture and planning fosters solutions that may or may not be appropriate in a given coastal setting. A new interactive platform providing rapid answers to solutions that would survive from feasibility to implementation has recently been launched. Using quick up-front first-order analyses, DHI powers your early decisions with DHI Coastal Screener. This simple, yet robust tool enables any coastal development stakeholder to master coastline dynamics effortlessly and avoid nature-defying solutions.

Creation of a shoreline morphology digital twin

Traditional shoreline evolution modelling has inherent shortcomings in the parametrisation of spatial effects. Although captured by detailed coastal models, their applicability is restricted to short time scale applications, on the order of hours to days. MIKE 21 Shoreline Morphology (SM) bridges the gap between including complex spatial effects and predicting shoreline dynamics that span years to decades. Open the door to new possibilities for simulating long- term shoreline morphological response in complex environments, in relation to both geomorphological setting and marine infrastructure.

Online planning of flood protection and emergency response

For easy access to dynamic flood and damage loss maps, look no further than DHI FloodRisk. This new web-based system with a user-friendly interface, enables anyone to test different climate scenarios, experiment with a mix of mitigation measures and even quantify their consequences. Use DHI FloodRisk in Early Warning mode to evaluate emergency response scenarios with different mobile protection measures. Now, safeguarding against coastal flooding and preparing climate change adaptation has never been easier.

Re-establishment of important coastal habitats

Seagrass is an important habitat in coastal and estuarine waters from both an ecosystem management and coastal protection perspective. It creates shelter, provides breeding grounds for key species, ambers re-suspension, traps sediments and dampens waves if present in significant meadows. By combining hydrodynamic modelling, wave modelling and ecosystem modelling, DHI has developed tools designed to assess areas where seagrass restoration initiatives are most likely to succeed.

Development of synergies between coastal and environmental protection

Coastal protection is often developed with the single aim of protecting against sediment loss. However, by applying an environmental design approach, coastal protection measures such as stone reefs can act as an important ecosystem hot spot while at the same time optimising their investment. Stone reefs are considered an oasis. They create habitats for a wide range of flora and fauna and attract birds and fish, making them preferred locations for anglers and divers.

An insider’s perspective on tackling coastal erosion

Between climate changes, expanding coastal cities and the growing recreational use of beaches and nearshore areas for surfing and other watersport activities, rising sea level is making coastal erosion a major challenge. We’ve asked an insider to share his perspective on trending integrated solutions which address both the risk to infrastructure and beach amenity.
