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...

The quantitative determination of bed-material-transport by means of tracers has been considered. For a stationary-stochastical transport-condition the dispersion of tracers has been described by a diffusion-equation of the gradienttype. The parameters of the dispersion-model are derived from the measured concentrations by a least-squares...

Collegedictaat f10. In deze handleiding kan slechts een eerste kennismaking met de problemen worden gegeven, die samenhangen met het transport van sedimenten als gevolg van de waterbeweging. Door de interactie van waterbeweging en sedimentbeweging is er sprake van gecompliceerde processen, die zich slecht ten dele theoretisch laten benaderen. Er...

In this thesis first a general derivation is given of the 'macro'-equations of mass- and linear-momentum balance that govern the mo'mentum transfer from a Newtonian fluid to rigid particles in a fluid-solid mixture. In particular, attention is paid to a) the attenuation of viscous-momentum transfer from the boundary to the interior of a granular...

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...

Als T.O.W. onderzoek is door het Waterloopkundig Laboratorium een onderzoek uitgevoerd waarbij enkele moderne zandtransportformules zodanig zijn aangepast dat de gecombineerde werking van golven en stroom in rekening kan worden gebracht. Uit dat onderzoek bleek dat de aangepaste White-Ackers formule het beste aansloot bij een serie modelproeven...

The Subcommittee 6 of the Technical Committee 113 of the International Standardization Organization (ISO) is dealing with measurements of sediment transport in open channels. As a back-ground paper for TC113 this report is written on the BTMA, internationally named the Arnhem Sampler. The BTMA has been developped jointly by Rijkswaterstaat,...

The probabilistic design method of a cover layer of pipe line under the horizontal bottom is described. By assuming that the water velocity at the bottom is Rayleigh distributed, probability of bottom shear stress was derived. With a combination of the probability function of bottom shear and a simple sediment transport formula given by Madsen...

Galappatti, R. (author)
A new depth averaged model for suspended sediment transport in open channels has been developed based on an asymptotic solution to the two dimensional convection-diffusion equation in the vertical plane. The solution for the depth averaged concentration is derived from the bed boundary condition and the computation of transport rate and...

An experimental study was carried out in the framework of a research project concerning the development of a mathematical model for morphological computations in rivers in case of non-uniform sediment. The study consists of a series of laboratory experiments in a straight flume under steady, uniform (equilibrium) conditions with a restriction to...

Many harbors in the world suffer from siltation in their basins and in many cases removal of the deposited sediment leads to high costs. This siltation results from a net transport of sediment into the harbor caused by the water motion in the harbor entrance. The water motion is very complex and of a three-dimensional nature. Three main...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is steady. The bed topography is measured by means of a profile indicator. The bed topography is characterized by a slowly damped oscillation of the transverse bed slope. Downstream of the bend entrance a pool and a...

The research that has been presented in this report is a part of an ongoing study on the siltation of tidal harbors. The study deals with the water motion in the harbor entrance, which motion causes the siltation. As yet, too little is known about this complicated time-dependent water motion. The data obtained during the research will be used to...

Bed-levelling experiments are conducted in a straight laboratory channel. The experiments involve a significant fraction of suspended sediment transport. The purpose of the experiments is to provide data for modelling of the direction of sediment transport on a transverse sloping alluvial river bed, specifically in presence of suspended sediment...

Derivations and analyses of basic equations for I-dimensional sediment-laden flow (concentrations up to about 10% of volume) on a mobile bed are presented . Equations of mass and momentum conservation have been derived by means of a control section as well as by depth integration. Therefore a three-layer approach has been used (i.e., bed layer,...

An entrainment model for fluid mud is derived by integrating the equation for turbulent kinetic energy across the mixed layer and introducing some modelling assumptions. The resulting entrainment model is similar to models of mixed-layer deepening in lakes and reservoirs, but in addition accounts for the work needed to entrain bed material. Two...
