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...

A two-dimensional horizontal mathematical model of the flow and bed topography in alluvial channel bends is presented. The applicability of the model is restricted to channels of which the width-depth ratio is large, the Froude number is small, bed load is dominant and grain sorting effects are negligible. First order analyses of the...

De Vries, M. (author)
In river engineering morphological predictions have to be made to study the implications of changes in a river system due to natural causes or human interference. It regards here time-depending processes. Characteristic parameters of the river have to be forecasted both in time and space. The morphological processes, however, are extremely...

Termes, A.P.P. (author)
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...

Olesen, K.W. (author)
The paper presents a linear perturbation analysis of a horizontal two-dimensional mathematical model for the flow and bed topography in straight alluvial rivers with dominant bed-load. A sediment transport model including effects of transverse bed slope, secondary (helical) flow and secondary flow inertia is employed. The stability and the...

De Vriend, H.J. (author)
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...

l model whithout this restriction this has been done by taking more grain fractions into consideration. (Model for non - uniform or graded sediment). This extension of the mathematical model for uniform sediment is described in chapter 1, where the basic equations of the model for uniform as well as for non - uniform sediment are derived. The...

Ribberink, J.S. (author)
In Chapter I a derivation of the equations and an extension of the mathematical model will be carried out. The sediment-mixture is separated in a number of fractions - each with a representative grain size - and the equations describing the sediment-movement are split up for every fraction separately. In order to get some insight in the new...

De Vries, M. (author)
Rather than reporting on a specific topic of current research in the broad field of sediment transport and river morphology, the writer will give a general contemplation on the state of the art. This will not be a review in the usual sense. The alloted space would then be filled easily with references. References will only be made here if it...

Uitgaande van de Reynoldsvergelijkingen met de bijbehorende randvoorwaarden wordt een vereenvoudigd wiskundig model afgeleid voor ondiepe bochtige rivieren. met als voornaamste uitgangspunten: - de vertikale afgeleiden van de snelheden zijn groot t.o.v. de horizontale - de schuifspanningseffekten overheersen de traagheids- (advectieve) effekten....

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...
