Cloud-based sediment modelling tool

Quickly predict dredging-related sediment spill plume dispersion for more proactive environmental impact assessments.


Sediment spill from dredging activities may affect sensitive and protected species as well as natural habitats. To reduce ecological risks, ensure regulatory compliance and optimise operations, dredging operators need an efficient way to conduct quantitative and precise impact assessments.
PlumeCast helps to predict sediment spill quickly through a web browser using state-of-the-art simulation software. This makes it easier to assess potential consequences on the environment and expedites approvals for new dredging activities. Save time and money with PlumeCast’s flexible assessment process and standardised spill control procedures that are scalable between projects. Anyone can use it as no special modelling expertise is required!

Assess potential impacts early

Quickly screen predicted sediment spill during the planning stage as required for an Environmental Impact Assessment (EIA)

Proactively manage spills during operations

Forecast spill plumes for the following days and use those results to guide your mitigation strategy

Anyone can use the application - no special modelling expertise required

You don’t need a modelling expert on your team to use PlumeCast thanks to its straightforward and easy-to-use interface.

Have confidence in the accuracy of the results

PlumeCast uses MIKE Powered by DHI’s proven technology and cloud-optimised computational engines to model hydrodynamics, sediment dynamics and shading effect on bottom vegetation

Save time and money

Complete the approval process faster with a subscription to PlumeCast versus the higher cost and learning curve associated with traditional modelling software

Key application areas

Use PlumeCast to:
  • Support an Environmental Impact Assessment (EIA) as required to obtain dredging approval
  • Optimise your dredging strategy
  • Screen potential impacts for designed scenarios
  • Assess the effectiveness of mitigation measures such as silt curtains
  • Forecast spill plumes during operations to proactively manage potential impacts

Get started!

PlumeCast is easy to use. Simply enter the details of your dredging operation and execute the simulation. You will soon have results in hand that can be animated for easy visualisation and sharing with others.

It’s all about quality

At DHI, we have designed technology for solving complex challenges in offshore, coastal and marine water environments since 1964.

We answer the demands of today’s market and customers asking for better and actionable data and information.

PlumeCast builds on the analytical capabilities of MIKE Powered by DHI’s hydrodynamic, sediment and ecosystem dynamic engines by translating simulation results into actionable information.
