De Koning, R.J. (author)
The study into sand wave dynamics in South Channel has commenced after large dune forms were observed in monitoring campaigns following the channel deepening project of the Port of Melbourne. The project involved deepening of the harbour berths and channels, but more importantly, it involved the deepening of South Channel in Port Phillip Bay....

The large-scale 3D printing technology created by a group of partners led by DUS Architects allows fabricating components made of thermoplastic polymers with Fused Deposition Modelling technique. These components can be used as moulds for concrete elements, providing freedom of form and unprecedented optimization opportunities. In this report...

In hydrological models evaporation is often still quite uncertain. Potential evaporation is used as input, but the modelling of plant stresses is not always accurate enough to describe the behaviour in reality. In situ measured actual evaporation data is rare, and doing measurements is time consuming and expensive. With the advance of satellite...

This study shows how historical topographic maps of the Zuid-Limburg mining area can be used to estimate the effects of mining activities on vertical ground surface motion. Coal has been the most important energy supplier for the Netherlands from the 19th century until the discovery of the large Slochteren gas field. After 1960, mining of coal...

In this study the prediction of stratocumulus occurrence by the Large-Eddy Simulation model DALES was investigated. The performance of DALES was compared with that of the large-scale weather model RACMO. A method was developed which can consistently initialise the model by assimilation of observations in addition to large-scale weather model...

Many reservoirs are considered unsuitable candidates for Enhanced Oil Recovery. Surfactant-Foam flooding, also referred to as Low-Tension-Gas flooding, could be a solution to enhance the oil recovery in tight, saline or high temperature reservoirs. SF-flooding combines reduction of the oil-water interfacial tension by surfactant, with mobility...

Enhanced oil recovery by gas injection can show excellent displacement efficiency but may suffer from poor sweep efficiency. A promising method to overcome poor sweep efficiency in gas-injection enhanced oil recovery processes is foam injection. The effect of oil saturation on foam stability is complicated and not fully understood. Complexity in...

Simulation of reservoir operations is important to investigate the effects of climate change and changes in human water demands on water availability in the future. Several reservoir simulation models exist, however it is unknown in which situations what type of model could be applied. This study tries to give an answer to the question how...

Doff, J.M. (author)
The goals of this thesis were to understand the impact of uncertainties and modeling methods on the resulting stress and strain patterns and to see how 3D stress patterns can be linked to what was seen in the field. In 3 types of models simulations were done to carry out this goal. These are the 2D perturbation model, the 2D static model, and...

In the region of the Riau Islands of Indonesia fresh water scarcity is one of the challenges the local community is facing. In order to increase the catchment of fresh water the choice is made to turn Bintan Bay, part of the Riau Islands, into a fresh water reservoir. Hereby collecting the fresh water runoff from local rivers. It is however...

Offshore sand waves of several meters high and hundreds of meters long are formed in shallow seas due to the tidal currents. These sand waves can, amongst others, influence the burial depth of cables of offshore wind farms and obstruct navigation channels. For the Far Large Offshore Wind programme (FLOW), one of the goals of Deltares is to...

Broekema, Y.B. (author)
In this study a modelling approach was investigated that takes into account the effect of short wave grouping on long wave motions, calculating sediment transport and morphology with multiple fractions and a layered bed stratigraphy. After extensive testing and validating this model using data collected in a wave flume in Hannover this model was...

The interaction between vegetation and the morphodynamics is considered to be an important process in salt marsh formation and succession. Therefore, the contribution of vegetation modelling on the long-term morphological development of salt marshes is assessed by implementing a vegetation growth model in the morphodynamic modelling software...

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...

Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...

This master thesis comprehends a study on khettaras, historical subsurface drainage tunnels, in East Morocco. A numerical groundwater model was set up to simulate these systems and to get a better understanding of their behaviour. Subsequently, the model was used to simulate the effect of several scenarios: increased use of pumped wells in the...

A common practice for hydrologists to determine the performance of a hydrological model and its parameter values, is by calibrating the model parameters on observed discharge data, but this data is not always available. For this reason, other data should be used as complementary data in order to reduce the uncertainty of outflow and processes in...

Pathogens are present in our urban water system, and may pose a health risk to swimmers and playing children. Although the knowledge of pathogens has increased over recent years, little is known about their behaviour in the urban water system. The goal of this thesis is to investigate this. First, the behaviour of pathogens under the influence...

The Altiplano Basin (Bolivia) exhibits one of the best examples of dryland river systems with a low gradient, where it is possible to obtain field data to build 3D high-resolution geological models of different sediment bodies. This study presents the development and understanding of a 3D geological model for crevasse splays deposited in this...
