This report describes the work performed on the experimental setup and initial characterization of the Alternative Low Power Hybrid Ion Engine (ALPHIE) plume performed at the Universidad Politécnica de Madrid (UPM) Plasma Laboratory. First, a general background of plasma thrusters is presented, followed by a review of relevant plasma parameters...

The search for life in other celestial bodies has always been a topic of great interest within the scientific community. The curiosity to know if we are the only ones in the universe or not has driven the development of many engineering projects. This Master Thesis is meant to do its bit in this research field. Europa, a moon of Jupiter, is...

Europa, the second of Jupiter’s Galilean moons, has attracted strong interest from the scientific community. This is because it could harbour a sub-surface ocean of liquid water beneath its icy surface, which could be habitable. Recent observations indicate the existence of water vapour plumes at Europa’s south pole. The in-situ measurements of...

By its very nature dredging is an environmental impact, since dredging includes the excavation and/or relocation of sediment in a river, sea or estuary. One of the environmental impacts related to dredging is increased suspended sediment concentration (SSC) levels, forming plumes of sediment. These so called dredge plumes originate from spillage...

Dredge plumes and ecology have become increasingly intertwined in recent history; one of the more prominent reasons behind this is the influence of clouds of fine sediments released in the open water due to dredging (`dredge plumes') on for `sensitive receivers' such as coral, seagrass and mangroves. An Environmental Risk Assessment (ERA) in...

Becker, J.H. (author)
Nowadays, the ecological effects of dredge plumes are usually managed based on the precautionary principle. Predictions of suspended sediment levels are made, which have to be compared to thresholds set by the responsible authority. Failing to comply may cause a project to be delayed and thus lead to additional costs. The precautionary principle...

This Master Thesis presents a numerical model analysis of the response of the Rhine ROFI on wind direction and speed. The aim of this study is to gain a further insight in the physical processes of the Rhine ROFI. Previous work on the Rhine ROFI focused mostly on tidal effects (straining and mixing) and inertial motions (earth rotation). Other...

The overflow mixture of hopper dredgers contains fine sediment which when released in the environment forms a so-called plume. The spreading of this sediment and the related turbidity increase and sedimentation pattern can be of environmental importance. Understanding the behaviour of these plumes is therefore important. The first phase of the...

Arentz, L. (author)
The data content of remote sensing (RS) images of sea surface temperature (SST) and normalized water-leaving radiance (nLw), for the year 1998, with respect to the River Rhine plume, is investigated. Questions that this study tries to answer are: is it possible to identify the plume from the available RS images, and under which conditions is...
