Hydraulic engineering

The Netherlands lies on the water and many structures are located on the border of land and water, such as harbours, quay walls and locks. The interaction between water and soil - always important in geotechnical engineering - becomes doubly important here because the water also touches the structure 'from outside'.

Design guideline Geotextiles under stone revetment (2017)

In hydraulic engineering, there appears to be no effective design philosophy that ensures damage-free installation of geosynthetics under set and loose poured stone in hydraulic structures. In particular, preventing damage to the geosynthetic during stone pouring has never really been well mapped. The publication Design guideline Geotextiles under stone revetment offers a change in this.


Handbook Dredged material in geotextile tubes: Accelerated dewatering and application in practice (2017)

This handbook brings together the practical experiences gained and provides an overview of the main advantages and preconditions when using dredge tubes for the accelerated dewatering of dredged material. The focus here is on use where the dredge tube has been applied as a construction element.

Storm surge barrier with movable floor doors (2014)

As part of the MOSE project, a new storm surge barrier in the Venice Lagoon to close it off from the Adriatic Sea, a system of eight caissons has been sunk near Chioggia. Movable flood doors will be placed in these so that the system can be closed during extremely high tides.


Handbook on inner-city quay walls (2014)

Inner-city quay walls are often centuries-old masonry structures founded on wooden piles. They often still function without problems, but defects and sometimes even collapses are also observed. This handbook therefore aims to provide a unified safety philosophy for designers, with tools for inspection, management and maintenance.


Handbook Quay Walls (2013)

This handbook provides state-of-the-art guidance on the design, construction and management of quay walls in harbours. Designing with finite element programmes is also possible using this handbook.


Handbook of hydraulic fills (2012)

In many parts of the world, sites are reclaimed for ports, industry and sometimes housing. With the knowledge disclosed in this handbook, a sophisticated design of such sand fills can be made. The handbook is a source of information for clients, consultancies and contractors.


Implementation of geosynthetics in hydraulic engineering (2011)

Because it is not always clear who monitors the quality of geosynthetics and how such inspections should be carried out, CUR Recommendation 115 has been drawn up. This provides clarity on material properties, quality controls and implementation aspects. The aim is to improve the quality of the execution, thus enhancing the properties of these products.


Stability of granular filter structures (2010)

In hydraulic engineering, granular filter structures are used in many places as protection against erosion. In bridge piers, for example, this type of fractured stone construction is common. The filters consist of layers of granular material of different grades. With filters, both the internal stability in the filter material and the stability of the boundary layer between base and filter material must be guaranteed. Because loads on existing structures are greater than had been assumed in the past, and because a lot of highly graded gravel from river floodplains is expected to enter the market, further research was needed on interface stability in filter structures. This research resulted in new formulae for geometrically open filters. These formulas and their derivation are presented in this CUR report 233.


Delft Cluster: Sustainable development of the coastal zone (2008)

Results of research into, among other things, geotechnical processes in the coastal zone. This has, for example, developed innovative techniques for sedimentation prediction. The Delft Cluster research programme (2003-2011) was set up to promote the development and dissemination of knowledge for the civil engineering sector.


Delft Cluster: Stone settlements (2007)

Research into the knowledge gap concerning the contribution of clamping to the stability of stone revetments under wave attack. Among other things, tensile and shear tests were carried out in the field to verify the bedding model for clamped stone settlements. The Delft Cluster research programme (2003-2011) was set up to promote the development and dissemination of knowledge for the civil engineering sector.

Geocontainers suitable for building large-scale sand bodies

Dumping gigantic sandbags onto the seabed using a so-called split bucket. Research by Delft Cluster shows that this is a suitable method for the construction of a second Maasvlakte or a large-scale sludge storage depot at sea. The condition is that the placement accuracy requirements are not too strict.

Sensible sand separation

For optimal utilisation of dredging deposits, it makes little sense to apply sand separation at sand contents of 60% or lower. That is one of the results of Delft Cluster's study 'Development of underwater soils'.

STOWA

The Foundation for Applied Water Research (STOWA) is the knowledge centre of regional water managers in the Netherlands. STOWA develops, gathers and disseminates knowledge needed to properly implement the tasks facing water managers. Examples include climate adaptation, proper implementation and execution of the WFD and safe regional water defences. The knowledge can be in applied technical, natural scientific, administrative-legal and social-scientific fields. STOWA 's website features reports, software, current themes, news and discussion forums on water management.
