通过三维CFD模拟、室内实验和现场测量，对湍流近场溢流尾流的掺混有了更深入的了解。重点一直放在最常用的挖泥船上：一艘拖吸式料斗挖泥船(TSHD)。近场溢流疏浚羽流混合很重要，因为它决定了远场疏浚羽流的特征和沉积，这对于评估疏浚工程的环境影响是必不可少的。在这项研究中，确定了最重要的近场混合过程。这些见解被转化为可用于日常疏浚工程实践，并用于改善(影响减少溢流扩展)概念，以减少对环境的影响。
3D CFD simulations, lab experiments and field measurements are used to get more understanding of the turbulent near field overflow dredging plume mixing. The focus has been on the most often used dredging vessel: a trailing suction hopper dredger (TSHD). Near field overflow dredging plume mixing is important because it determines the far field dredging plume characteristics and deposition which are essential to know in order to be able to assess the environmental impact of a dredging project. The most important near field mixing processes have been identified in this study. The insights are translated to be usable in every day dredging engineering practise and used in the IMPROVE (IMPact Reducing OVerflow Extension) concept to reduce the environmental impact.
