Coastal Flood Modelling Software

Analyse, model and simulate flood risks

Gain powerful insight from hydrologic and hydraulic models to assess the potential impact of coastal flooding on the built and natural environment to help design appropriate flood defences.

Choose the modules you need for maximum flexibility

The modular structure of MIKE Powered by DHI software offers the most advanced functionality with maximum flexibility as you can pick and choose which combination of modules are best suited for the nature of your work and intended outcome. Alternatively, select from one of our pre-bundled software subscriptions.

Get started with these Core Modules

MIKE Preprocessing & Postprocessing (PP) and MIKE 21 Hydrodynamics (HD) are the foundational tools for performing all coastal flood modelling work.

Transform raw data into an understandable format
  • Begin your data visualisation journey with an integrated work environment and compatible routines to ease data input, analyses and presentation of modelling results
  • Use PP to create efficient model mesh using mixed elements
  • Features a tidal and boundary condition generator
  • Convert wave spectra data into model format
  • Generate 2D time-varying hurricane or cyclone wind forcing files to perform storm surge modelling

2D modelling of hydrodynamic processes
  • A central component to most modelling tasks, understand coastal inundation through the simulation of water levels and 2D free surface flow in response to boundary conditions
  • Seamlessly represent storm surge caused by wind and pressure
  • Model sub-grid features such as culvert, weirs and dikes
  • Simulate wave driven currents
  • Couple MIKE 21 HD with 1D river channel and 1D urban drainage network models for more robust flood studies

“By using MIKE21 HD to model future storms influenced by climate change, we can use the results for sustainable planning to control the risk of flooding in the Limfjord.”

Add Supplemental Modules for increased functionality

Choose from a curated selection of supplemental modules with specialised features and configurations that allow you to address any coastal flooding challenge.

Analyse and predict wind generated waves
  • Simulate the growth, decay, and transformation of wind-generated waves and swell
  • Assess wave climates in offshore and coastal areas in hindcast and forecast mode
  • Includes the main physical phenomena including wave-wave interaction, white-capping, dissipation, refraction and shoaling
  • Couple with Hydrodynamics (HD) and process engines for enhanced optimisation
  • Features a tidal and boundary condition generator
Simulate wave breaking, wave run-up and overtopping
  • Perform 3D simulations of all physical transformation wave processes for coastal flood studies
  • Understand the impact of strongly nonlinear waves and infragravity waves caused by breaking waves
  • Calculate wave transmission and reflection through the representation of a porous structure with natural porosity versus using semi-empirical formulas
Assess changes to shoreline morphology
  • Undertake long-term shoreline morphodynamic simulations in 2D environments for complex bathymetries or coastal structures which are challenging for standard one-line shoreline models
  • Combine cross shore profiles with 2D modeling including hydrodynamic, wave forcings and sand transport techniques
  • Calculate dune erosion during storm events

Predict the fate of sand due to currents

  • Make short and long term predictions of sediment transport capacity and resulting bed level changes for non-cohesive sediment (sand) due to currents or combined wave currents
  • Perform fully dynamic coupled morphological simulations with HD, Wave, and ST modules

Predict long-term coastal evolution

  • Efficiently simulate a wide range of wave and current scenarios along straight or nearly straight coastlines
  • Make predictions of coastal profiles, sediment budgets and long-term coastline evolution by accurately calculating littoral drift for robust coastal zone management

Simulate mud transport, settling and deposition

  • Efficiently simulate a wide range of wave and current scenarios along straight or nearly straight coastlines
  • Make predictions of coastal profiles, sediment budgets and long-term coastline evolution by accurately calculating littoral drift for robust coastal zone management

“DHI’s new powerful MIKE 3 Wave FM model has been an extremely valuable tool for assessment of coastal flooding due to wave overtopping. In addition, the 3D visualisation of the results has been a game changer for illustrating the risk prone areas to the many stakeholders.”

Analyse the impact of flood water on urban infrastructure or a river channel network

These modules are also compatible with MIKE 21 and can help address water quality, saltwater intrusion, contaminated water overflows, infiltration, and fluvial flooding concerns.

Simulate distributed rainfall and infiltration in urban areas

  • Perform flood impact assessments and create hazard maps using this core element of MIKE FLOOD
  • Couple with MIKE HYDRO River, MIKE URBAN collection systems, and MIKE 21 2D surface flow to create an all encompassing three-way modelling tool for more dynamic coastal flooding studies

Model the impact of flooding on urban infrastructure

  • Simulate unsteady flow in pipe and channel networks taking into account overland flow and sewer networks
  • Locate and manage contaminated water overflows in a coastal flooding event
  • Model the inflow of seawater, as normal water, in a pipe network

Perform wet weather management tasks

  • Analyse rainfall dependent inflows and infiltration mitigation as a response to urban flooding
  • Includes multiple rainfall-runoff models such as time area method, kinematic wave and linear reservoir
  • Features a Rainfall Dependent Infiltration (RDI) module

Model the impact of flooding on a river network

  • Model river hydraulics, water quality, flooding, forecasting, catchment dynamics and runoff
  • Understand the impact of coastal flood water on your river channel network and the use of river water (e.g. potable water extraction)
  • Manage river flood control structures in a fully integrated way

Perform water quality and ecological studies

  • Analyse the impact of flood water on water quality for remediation planning and permitting
  • Make spatial predictions of ecosystem response to contaminated flood water including agricultural productivity
  • Assess the public health risk of exposure to waterborne diseases

Calculate flood damage costs and risks

  • Assess and document the impact of flooding on a city due to rising sea levels and/or extreme rainfall events with this user-friendly, yet powerful tool
  • Create damage and risk maps based on GIS data to provide valuable input to decision makers for prioritising between various mitigation options
