Watershed management index based on the village watershed model (VWM) approach towards sustainability

Sriyana, Ignatius (author), de Gijt, J.G. (author), Parahyangsari, Sri Kumala (author), Niyomukiza, John Bosco (author)

In the current study, we examine the Indonesian government's watershed management program, which was established in 2001. In 2005, the Coordination Team for Rescue of Water Resources (CTRWR) was established to execute the program on a national level. However, at the time, field implementation was a sectoral interest due to the lack of program...

The potential of using performance information in the assessment of existing quay walls

Den Adel, N. (author), de Gijt, J.G. (author), Wolters, H. J. (author), Schweckendiek, T. (author)

The design of new and assessment of existing quay walls is subject to large uncertainties. Dealing with these uncertainties is a crucial part of the engineering process. The way uncertainties are addressed has a large impact on construction and maintenance costs and on the reliability ultimately obtained. Especially in the assessment of...

Some learning cases in the Port of Rotterdam

de Gijt, J.G. (author), Brassinga, H. E. (author), Roubos, A.A. (author)

This paper present several cases in the Port of Rotterdam where both in the design and construction phase several different did not marched as expected. These cases are interesting for both the design as well the construction phase of a project. People will make mistakes however the mistakes describes in this paper have to be judged in time...

Relationship between the construction costs and the reliability index of quay walls

Wesstein, R. (author), de Gijt, J.G. (author), Heeres, O.M. (author), Roubos, A.A. (author)

Structures, such as quay walls, have to meet a particular level of safety. Consequently, in the Eurocode standards, three reliability classes are distinguished, each corresponding to a target reliability index and set of partial factors. In this study, more insight is acquired into the relationship between the quay wall's construction costs...

Effect of noises removal and spatial resolutions of Digital Surface Model (DSM) in flood inundation model

Yunika, A. (author), Kok, M. (author), de Gijt, J.G. (author), Huizinga, J. (author), Ginting, S. (author)

Digital Elevation Model (DEM) is an important component in flood inundation modelling as a part of flood risk analysis. However, Digital Surface Model (DSM) which still contains noises of artefacts is more common to be available than DEM. Then DSM misleads the inundation extent. This study will evaluate a measure to obtain a bare-earth...

Stability Analysis Quay Wall at the Amazonehaven, Port of Rotterdam

Mourillon, Nadevah K.N. (author), de Gijt, J.G. (author), Bakker, K.J. (author), Brassinga, Henk (author), Broos, E.J. (author)

The stability of any structure is an important aspect in civil engineering. This aspect is the subject of the researched quay wall at the Amazonehaven, port of Rotterdam. The quay wall with a relieving platform structure had in various section, over the entire 900m length of the quay, large deformations at the toe of the combined wall. The...

Lowering the Beneluxtunnel

Weeda, Tomas (author), de Gijt, J.G. (author), Bakker, K.J. (author), Braam, C.R. (author), Broos, Eric (author), Jonkman, Sebastiaan N. (author)

As a result of the persistent increase of container vessel dimensions, future problems regarding navigation draught in the presence of tunnels are becoming more likely to occur. Hence, possible solutions to this problem have been investigated for the Beneluxtunnel. Several design options have been elaborated to determine the technical and...

Specifying risk management standard for flood risk assessment: A framework for resources allocation

Yunika, A. (author), Kok, M. (author), de Gijt, J.G. (author)

General risk management standard, e.g. ISO 31000:2009, approaches risk as a coin with a pair of two sides, i.e. the threat and the opportunity. However, it is hardly the case of flood events which mainly come as threats. Despite the contrary, this study explores the potential applicability of the available risk management standards specifically...

The gelsluice, an innovative idea for the present sluice structures

de Gijt, J.G. (author), Heester, B.A. (author)

Sluices have been built worldwide since in 984 when the first sluice was built in China to speed up the operations in the Grand canal. Since that time different types of sluices have been developed world wide both in size and material use and their own shipping and structural characteristics. One of the main drawbacks of the present sluice...

Evaluation of performance of analytical and numerical methods to account for liquefaction effects on the seismic response of anchored quay walls

van Elsäcker, W.A. (author), Besseling, F. (author), Lengkeek, H.J. (author), Brinkgreve, R.B.J. (author), de Gijt, J.G. (author), Jonkman, Sebastiaan N. (author)

Liquefaction induced by earthquakes has shown to have potential devastating influence on seismic performance of anchored quay walls. Therefore, measures to mitigate liquefaction are commonly part of the design of quay walls in<br/>seismically active regions. Such mitigation measures are costly. Moreover, these measures are difficult to implement...

Widening a harbor basin, demolition of a deep see quay wall in Rotterdam

Broos, E.J. (author), Sibbes, R. (author), de Gijt, J.G. (author)

The rapid development in containership dimensions creates a huge challenge for ports. But for one port basin in Rotterdam this challenge was too big. The nautical restrictions for the Amazonehaven would start at such moderate conditions that the basin would be closed for Ultra Large Container Ships (ULCS) about a 100 days a year. As this basin...

Model Solutions for Performance-Based Seismic Analysis of an Anchored Sheet Pile Quay Wall

Habets, C.J.W. (author), Peters, D.J. (author), de Gijt, J.G. (author), Metrikine, A. (author), Jonkman, Sebastiaan N. (author)

Conventional seismic designs of quay walls in ports are mostly based on pseudo-static analysis. A more advanced alternative is the Performance-Based Design (PBD) method, which evaluates permanent deformations and amounts of (repairable) damage under seismic loading. The aim of this study is to investigate the suitability of this method for...

Resilience to flooding: Draft building code

A significant issue associated Flood Defence Systems (FDS) is the difficulty of predicting how these structures will behave when inevitably they have been loaded beyond their designed capacity by a flood. The flood can cause these structures to fail catastrophically with loss of life and substantial damage to property. For a limited incremental...

Reliability of quay walls using finite element analysiscalibration of partial safety factors in quay wall design by probabilistic plaxis calculations

Wolters, H.J. (author), Bakker, K.J. (author), De Gijt, J.G. (author)

During the last two years, CUR committee 183 has worked on the upgrade of the Dutch Quay Walls handbook (CUR 211), which is to be published in 2013. Two of the main elements that are considered in this new edition are the addition of Finite Element analysis (FEM) as a method for design, comparable to the description in the Handbook Sheet-Pile...

The feasibility of removable prefab diaphragm walls

Amaarouk, R. (author), De Gijt, J.G. (author), Braam, C.R. (author)

A diaphragm wall is a cast in-situ reinforced concrete retaining wall applied in, among others, quay walls. The main advantages of this type of retaining wall are that it can be made in almost every preferred length and that it can resist high structural loads. However, there are several disadvantages: sufficient concrete cover on the...

A comparison of a 3 dimensional probabilistic method of berthing structure design and the traditional method of a berthing structure design

Kool, J.J. (author), De Gijt, J.G. (author), Groenewegen, L. (author)

Finite element method (FEM) is increasingly applied as a first choice tool for designing structures. The same trend is seen in probabilistic designing. Consequently, the application of the combination of these two methods is discussed in this paper.In this study the presence of potential overcapacity in a structure has been studied. As an...
