The beach at Ngapali, Myanmar is eroding, resulting in a shoreline which moves landward. The coastline gets closer to the vegetation each year and during the monsoon season, at high tide, it reaches the palm trees completely. The assumption is that this is due to people shovelling truckloads of sand from the beach to use for construction, this...

The use of fibre reinforced composite polymeric materials for primary helicopter structures has been increasing over the last decades due to their attractive properties; high performance and lightweight inducing more fuel savings than their metallic counterparts. With respect to the joining methods; structural adhesive bonding is preferred when...

A very common observation is the episodic erosion of beaches during storms and the slow recovery (accretion) afterwards (Yates et al. 2009). Morphodynamic models parameterize physical processes in order to relate the fluid motions (hydrodynamics) to the bed level changes (morphodynamics) over a wide range of spatial and temporal scales. Despite...

This work is carried out in collaboration with Dunea and TU Delft. The aim of this study was to optimize the ripening period of slow sand filters and to identify the indicators of ripening. Combination of full scale and column scale slow sandfilters...

Great Lakes Dredge & Dock (GLDD) is one of the biggest dredging companies in the USA which provides engineering services in dredging and land reclamation. GLDD came up with an idea to develop a working model that can estimate spillage when using a cutter suction dredger (CSD) for cutting soft material like sand. The main reason for this is...

The Sand Engine is a new innovation in coastal protection, a mega feeder nourishment. This pilot project was constructed in 2011 along the Delfland coast, which is historically prone to erosion. Since its construction, the Sand Engine is intensively being monitored to track the morphological development.<br/><br/>The objective of this thesis is...

With the implementation of new legal aspects for dune safety assessment in 2017, the current method, Duros+, is no longer feasible to represent the desired processes. This 1D deterministic, volume-balance model cannot simulate processes like inundation and overwash, which are crucial to fulfil the new requirements for dune safety assessment....

Sand replenishments, or nourishments, have been the prevalent strategy of the Netherlands for coastal protection since 1990. In consideration of the expected sea level rise and potential increases of storm surges as a result of climate change, an innovative pilot project known as the ‘Sand Engine’ has been implemented. In contrast with...

Dams are an essential part of the Dutch flood defence works to protect the hinterland from flooding by the sea. Sand closures are the construction of closure dams with sand as the main building material. The rising and falling tide generates a current through the closure gap, which increases in strength as the gap becomes smaller. This current...

This document describes a study into the influence of alongshore bathymetric variability on currents which form a risk to bathers. Changes to coastal zone management along the Delfland Coast have given rise to questions on the influence of alongshore bathymetric variability on bather risk. Extensive measurement data is available from two...

This report describes and analyses small scale plough process. This research is initiated by Deltares and the Delft University of Technology as an experimental way to gain insight in the ploughing of the river bed in rivers. The main target of this thesis is to gather information on the plough process as applied in the maintenance of the Waal...

After the Deepwater Horizon oil spill in 2010, oil was released into the Gulf of Mexico and partly reached the shorelines. Here, it mixed with sand in the surf zone to form sand and oil agglomerates (SOAs). These cm-sized particles are heavier than water and are therefore found on the seabed. Years after the initial formation of these particles,...

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....

A landfall operation is conducted whenever a pipeline reaches the shore, during this operation the pipeline is pulled onto shore with the help of a steel wire rope. Allseas engineering has experienced several cases of landfalls during which the friction forces along the steel wire rope rose to excessively high levels. These cases occurred at...

The objective of this research is to explore the feasibility of detecting sandy beaches at a high spatial level, using satellite images. A pixel-based classification scheme of the four classes selected (sand, mud, vegetation and gravel) is conducted, using Landsat 8 Top-of-Atmosphere images (years 2014 and 2015) and Google Earth Engine. Moreover...

Landfall operations are conducted for connecting an offshore pipeline with process facilities on the shore. During a landfall operation an offshore pipeline is pulled by means of a steel wire rope on the shore with a velocity of 7 cm/s. During this process the steel wire rope interacts with the soil located on the seabed and on the shore....

The increase in complexity of geotechnical problems demanded for more advanced physical modelling and instrumentation approaches. Physical modelling under normal gravity (1g) or in centrifuge has been an important instrument to overcome various scale issues that govern soil related experiments. However, limitations in the size, especially for...
