Fast assessment of dredging impacts in any water environment

DHI PlumeCast - an online application for the modelling of sediment spill

In order to obtain approval from the authorities to undertake dredging activities, companies are usually required to predict the expected sediment spill and assess potential consequences on the environment.

This is where DHI PlumeCast comes in. This new cloud-based service is used for the fast screening and impact assessment of dredging operations in the planning phase. It is also used in the operational phase to forecast spill and proactively manage spill impacts.

DHI PlumeCast will completely transform the way sediment spill is being modelled in any water environment. Its simple interface means that advanced models can now be operated by non-modellers through an easy-to-use web browser.


Sediment spill from dredging activities may affect sensitive and protected species and natural habitats. Quantitative and precise assessments of the impacts not only help to optimise dredging operations and compliance, but also reduce the risk for unforeseen effects on the marine ecosystem.

Imagine having the ability to conduct fast screening and assessment using state-of-the-art simulation software through a web browser. At the same time, you will be able to ensure flexibility in the assessment process as well as standardised spill control that is scalable between projects.

The process is so simple – no special modelling expertise required.

Planning stage

Impacts can be simulated upfront for quick screening and environmental impact assessment (EIA) required for approval of projects

Dredging operation

Forecast spill plumes for the following days and use results for proactive management of spill impacts

User friendly interface

The straightforward and easy-to-use interface makes the online platform attractive for non-modelling experts

Based on state-of-the-art models

The hydrodynamics, sediment dynamics and shading effect on bottom vegetation are modelled using MIKE Powered by DHI’s cloud-optimised computational engines

Significant savings

Today, the process of modelling impacts from sediment spills is costly and time consuming. With a subscription to DHI PlumeCast, you can significantly reduce the time and costs on your application for approval.

Key application areas

DHI PlumeCast can be used in:

  • Environmental Impact Assessments
  • Optimising dredging strategy 
  • Screening of impacts for designed scenarios
  • Operational spill control and management

Get started!

DHI PlumeCast is easy to use. In just a few simple steps, you can run a dredging scenario, assess it quickly and share the results with others. Simply start by keying in details of the dredging operation, execute the simulation job, view the results and animate it after.
