MIKE 21 Shoreline Morphology
Long-term shoreline evolution modelling

MIKE 21 Shoreline Morphology

Support advanced engineering studies on coastal morphology and evolution


The MIKE 21 Shoreline Morphology (SM) module offers best-in-class functionality for modelling the morphological evolution of coastal areas and shorelines. It enables users to simulate changes in coastline profiles, beach erosion, sediment transport, and shoreline dynamics over time due to natural processes or human interventions.


Engineered for environments featuring large curvatures, offshore reefs, breakwaters, and beyond, MIKE 21 SM serves as an essential resource for crafting resilient shoreline models and refining port layouts. Through its fusion of 1D shoreline evolution with 2D sediment transport modeling, MIKE 21 SM equips users to address complex engineering challenges effectively. Embraced by coastal engineers, researchers, and environmental consultants, it's pivotal for managing coastal hazards and preserving environments.

Areas of application

Climate change resilience and impact

Predict shoreline changes due to rising sea levels and intensified storms by integrating tidal dynamics and river sediment impacts.

Coastal engineering studies

Optimise coastal defenses by modelling the impact of structures like artificial reefs on shoreline stability and erosion.

Coastal erosion strategies

Predict erosion trends and evaluate the effectiveness of shoreline protection measures by modelling  interactions with sediment dynamics.

Environmental Impact Assessments

Provide detailed forecasts of shoreline adjustments to evaluate environmental impacts of coastal and offshore projects.

Optimisation of dredging operations

Assess the effects of dredging on shoreline morphology and mitigate sedimentation issues with bypass operation schemes.

Ship navigation planning support

Improve navigational safety and efficiency by modelling the impacts of dredging on shoreline stability and sediment redistribution.

Wave impact assessments

Examine the impact of wave dynamics on shoreline configuration, supporting the design of wave-resilient coastal structures.
