Fast assessment of dredging impacts in any water environments

DHI PlumeCast - an online application for modelling of sediment spill

In order to obtain approval from the authorities to undertake dredging activities, it is usually a requirement to predict the expected sediment spill and assess the potential consequences for the environment.

DHI PlumeCast is for fast screening and impact assessment in the planning phase. It is also used in the operational phase to forecast spill and proactive management of spill impacts.

The new truly cloud-based service is about to completely transform modelling of sediment spill in any water environments. In fact, the service allows advanced models to be operated by non-modelers 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 optimize dredging operations and compliance, but also reduce the risk for unforeseen effects on the marine ecosystem.

Imagine screenings and assessments that are easily accessible for non-modelers in a web browser, but still based on state-of-the-art and recognized simulation software.

Ensuring flexibility in the assessment process and standardized spill control that are scalable between projects.

Planning stage

Impacts can be simulated up-front for quick screening and impact assessment (EIA) required for consenting.

Dredging operation

Forecast spill plumes for the next 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-modeling experts.

Based on state-of-the-art models

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

Significant savings

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