Thaking things further in the SPM journey: Creating the new journey into Strategic Portfolio Managment and successful implementation through new tool design for useability

Organisations have a lot of trouble with managing their portfolio.<br/>The portfolio is the set of projects the company is currently running. The consultancy Jigseye provides tools for that purpose called Strategic Portfolio Management (SPM). They created tools to support organisations in creating that overview and the next step to manage it as...

Suspended sediment behaviour of a reallocation pilot study in the port of Rotterdam: Gaining insight into the sediment dynamics of a reallocation pilot study, by using model hindcasts and measurements

The port of Rotterdam is located within the Rhine-Meuse estuary where a substantial amount of fine sediment transport takes place. Therefore, the port of Rotterdam is subject to significant siltation, requiring maintenance dredging to guarantee a sufficient nautical depth of fairways and harbour basins. To optimise the dredging strategy in the...

Trench Siltation near the ETM of a Well-mixed Estuary

To exploit its socio-economic functions, engineering measures are regularly applied in estuaries. Estuaries are, however, known to be very complex systems. Stemming from this complexity is the generation of a so-called estuarine turbidity maximum (ETM), which poses great siltation problems to the engineering measures. An engineering measure,...

Calibration of optical backscatter sensor for measurements of sediment transport through the Marsdiep inlet

In highly dynamic and vulnerable tidal systems such as the Wadden Sea, the importance of understanding natural processes and how they are hampered by anthropogenic pressure is highly demanding. Within these processes the sediment transport is one of the most challenging movements to be monitored. With this in mind, suspended particulate matter ...

Suspended Sediment Modelling in the Port of Rotterdam

This Master thesis presents an improved model for the transport of fine suspended sediment (SPM) in the Rhine region of fresh water influence (ROFI) and in the Port of Rotterdam. It is known that the transport of SPM in the Rotterdam harbor depends on marine as well as fluvial processes. SPM transport inside the harbor has been modelled in the...

Mooring Line Failure Detection of a Single Point Mooring System: a Model-Based Approach

Infant mortality is a significant problem in mooring design. The objective of this thesis is to design a generic fault detection system for mooring line failures, which can accurately detect a mooring line failure within a certain time frame. The research is done through Catenary Arm Leg Mooring (CALM) buoy systems, as this thesis is a Proof of...

Approach to the use of uncertainty for management purposes - study Case: Quantification of the uncertainty in the turbidity for the ecosystem of the Wadden Sea

Around the world, areas with unique ecosystems are prone to harmful factors deteriorating their environment. Management of these areas need knowledge on the ecological status of these areas, to make decisions for future problems. They need easily accessible information on indicators describing the conditions of these areas. Obtaining this...

Embedding carbon impact assessment in multi-criteria supplier segmentation using ELECTRE TRI-rC

In the past decade, there has been an increasing interest in green supply chain management, which integrates environmental thinking into supply chain management. Assessing a supplier’s potential for improvement is very important when an organization wants to achieve certain environmental targets concerning their supply base, taking into...

Scanning Probe Microscope-Based Fluid Dispensing

Advances in micro and nano fabrication technologies have enabled fabrication of smaller and more sensitive devices for applications not only in solid-state physics but also in medicine and biology. The demand for devices that can precisely transport material, specifically fluids are continuously increasing. Therefore, integration of various...

Parallel, Miniaturized Scanning Probe Microscope for Defect Inspection and Review

With the device dimensions moving towards the 1X node, the semiconductor industry is rapidly approaching the point where 10 nm defects become critical. Therefore, new methods for improving the yield are emerging, including inspection and review methods with sufficient resolution and throughput. Existing industrial tools cannot anymore fulfill...

Ultra thin films for sensing and heating of microprobes

This dissertation aims to advance the current state of cantilevers with integrated metal thermal and deflection sensing elements. Metallic sensing elements enable the use of alternative substrate materials (such as polymers), that tend to exhibit higher compliance properties and are more robust (less brittle) compared to Si or Si3N4 cantilevers....

On sedimentation processes in a stratified estuarine system

Schnelle Rasterkraftmikroskopie durch moderne Regelungstechnik und mechatronische Systemintegration

In atomic force microscopy (AFM) high-performance and high precision control of the scanning-system is crucial. At high imaging speeds the dynamic behaviour of the scanner may cause imaging artefacts limiting the maximum imaging rate. This contribution discusses recent improvements for faster imaging by utilizing modern mechatronic and control...

Process-based and Surrogate Modelling of Fine Sediment Transport in the Dutch Coastal Zone

Coastal zones which are known as the interface between continents and oceans are vital and important to human beings because a majority of the world's population live in such zones (Nelson, 2007). Coastal systems are among the most dynamic and energetic environments on earth and they are continuously changing because of the dynamic interaction...

A Hybrid Approach to Combine Physically Based and Data-Driven Models in Simulating Sediment Transportation

The objective of this study is to develop a methodology for hybrid modelling of sedimentation in a coastal basin or large shallow lake where physically based and data driven approaches are combined. This research was broken down into three blocks. The first block explores the possibility of approximating a physically based model using a data...

Modelling the seasonal dynamics of SPM with a simple algorithm for the buffering of fines in a sandy seabed

This paper discusses the application of a simple algorithm for the buffering of fines in a sandy seabed. A second layer is introduced in which fines may be stored during calm weather and from which fines may be resuspended during storms. The algorithm is applied first in a one-dimensional vertical (1DV) point model at a location in the North Sea...

Modelling of Cohesive Sediment Transportation, Deposition and Resuspension in the Haringvliet Mouth.

In the Dutch coastal zone, where the marine environment is characterized by shallow depths and highly energetic hydrodynamic conditions, the cohesive sediments, or mud, play an important role in the local morphology. For instance, mud deposits and high concentrations of suspended particulate matter (SPM) occur frequently, especially during...

Report of meeting on measurement of suspended solids in the Meuse

On June 19/20, 2007 a visit was paid to a suspended particulate matter (SPM) sampling and monitoring site in the Ourthe river (Liège region), between the confluence with the Vesdre river and the mouth of the Ourthe in the Meuse river. The next day, a workshop was organised in which backgrounds, methods and procedures for SPM sampling and...
