DHI PlumeCast
Plume dispersion assessments made simple
DHI PlumeCast is a cloud-based marine plume dispersion assessment application designed for analysing sediment plumes and modelling conservative or non-conservative substances such as bacteria and heavy metals. It equips consultants, regulators, utilities, and contractors with the tools to make fast, informed decisions—without requiring complex modelling expertise. By combining advanced environmental modelling with real-time data integration, DHI PlumeCast streamlines planning and compliance, reduces costs and optimises every stage of marine project operations—from design to execution.
The cloud-based platform eliminates the need for costly software installations and IT maintenance. Intuitive visual reporting tools make it easy to share results with regulators and stakeholders through secure, controlled access to the platform.
