Keynote lecture at the ICSE2006. Various types of scour can confront the engineer, who has to design and construct a hydraulic structure in a marine environment. The engineer is interested in the magnitude of the scour to be expected and its development in time. He hopes that such information, if at all available, is accurate and that he can...

Riad, K. (author)
It has long been observed that at most canal bifurcations the water diverted to the branch does not carry sediment in direct proportion to the rate of flow. Usually, the major part of sediment reaching a bifurcation is diverted into the small branches. This phenomenon has always bothered engineers responsible for the maintenance of irrigation...

Making use of a mathematical model solving the complete NavierStokes equations for steady flow in coiled rectangular pipes, fully-developed laminar flow in shallow curved channels is analysed physically and mathematically. Transverse convection of momentum by the secondary flow is shown to cause important deformations of the main velocity...

Alternate bars in rivers and streams develop as a result of differences in length scales involved in the adjustment of flow and sediment transport to irregularities of the bed. The amount of field evidence supporting theoretical insights is highly limited. Here, we present results from a large-scale field experiment in a 600 m long straight...

The objective of the study is the characterization of the non-uniform geometry of a mountain river and the development of a method that identifies this geometry. Identification of the geometry enables simplification of a certain river section in modelling, which can be applied in a wide range of applications, for example the prediction of water...

In order to predict waterlevel changes in rivers due to floodwaves and local bedshapes for navigation, the local behaviour of the riverbed should be known. In many cases the bed of a river ~onsists of dunes, which propagate downstraam due to the sediment transport along the dunes. In this report mainly the watermovement but also the sediment...

Bij overstroomde kribben in een rivier met uiterwaard zijn grootschalige horizontale wervels te verwachten. Het tijdsgemiddelde langssnelheidsprofiel in dwarsrichting is bepalend voor het ontstaan van grootschalige wervels. In het kribvak vindt een grote richtingsvariatie in ruimte en tijd plaats. Deze variatie zorgt voor een grote uitwisseling...

The flow in a river bend has a large influence on the cross-sectional profile of the bend. Due to the curvature of the bend a secondary flow, which is perpendicular to the main flow, occurs. The secondary flow is directed outwards in the upper part of the cross-section and inwards in the lower part of the cross-section. It causes by means of the...

In 2000 the Dutch government chose a new point of view for the Dutch rivers: “Room for the River”. This viewpoint is the basis for a new approach of high water protection in the Netherlands. Instead of strengthening and raising the dikes, solutions must be based on space and spatial quality. One of the suggested measures is the addition of...

Van Liebergen, J.C.G. (author)
This study contains two topics which are important for the use of a one-dimensional computer model, calculating morphological changes in time. Firstly, for a good prediction of the morphological changes by the model a good reproduction of the water movement and the sediment movement is necessary. One of the conditions for a good reproduction of...

Sinds begin jaren negentig wordt gewerkt aan plannen voor het Grensmaasgebied. Het Grensmaasgebied wordt gevormd door een gedeelte van de rivier de Maas, namelijk vanaf Maastricht tot aan Maaseik. Een van de maatregelen die voortkomt uit de Grensmaasplannen is rivierverruiming. Bij deze verruimingswerken komen grote hoeveelheden delfstoffen vrij...

Eerkens, J.W. (author)
In one-dimensional river modelling it is common to schematise the cross-section into a rectangular cross-section with a constant width. If a quasi-steady flow is assumed, the equilibrium longitudinal profile is known and unique: the bottom slope is constant and equals the water surface slope. However, numerical calculations at DELFT HYDRAULICS...

In een rivierbocht treedt een zogenaamde spiraalstroming op, waardoor het typische dwarsprofiel van een rivierbocht ontstaat: diep in de buitenbocht en ondiep in de binnenbocht. Hierdoor is slechts over een kleine breedte voldoende vaardiepte aanwezig en vormen bochten in de Waal een knelpunt in de rivier voor de scheepvaart. In het Waalproject...

The rivers on the slopes of the Kelud volcano in Indonesia are marked by steep slopes and fine sediment. Therefore often supercritical flow and large sediment transports occur. In this exploratory study a mathematical model has been developed for this type of rivers. The properties of this model are examined with an analysis of the...

This report consists of five major parts. In Part I agiobal description of the project is given. In Part 11 the results of the definition study are presented and in Part 111 the results of the functional and technical design. Part IV gives a description of the two developed computer programs (ODIRMO and CREADATA). In Part V the test cases for...

Van oudsher heeft Nederland te maken met rivieroverstromingen. Door de eeuwen heen werd er voortdurend strijd tegen het water gevoerd. Bedijkingen moesten de bedreiging van overstromingen beheersbaar maken met als gevolg dat sedimentatie en dus ophoging van het land nu plaats vindt in het winterbed van de rivieren. De rivieren komen hierdoor...

The importance of the Rhine and its branches is unquestionable. It has an important role as an attraction point to human activities and as a navigation channel from the North Sea into Europe. The present report is one of the numerous studies made for the Rhine branches, in this case the River Waal. The main "tool" used during this work is SOBEK,...
