Over the past decade, deep-sea mining (DSM) has received renewed interest due to scarcity of raw materials. Deep-sea mining has been spurred by the need for critical resources to support growing populations, urbanization, high-tech applications and the development of a green energy economy. Nevertheless, an improved understanding of how mining...

Columbia River estuary is being conducted by the U.S . Geological Survey. The necessity for information on water discharge, suspended and bed sediments, and radioactivity prompted the development of new measurement techniques and equipment suitable for estuarine conditions. Flow velocities and directions throughout the entire depth at a single...

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...

Ph.D thesis of Shields, original version in German. This document is the basis of all modern sediment transport formulae, and develops the concept of bed shear stress.

Different measures will be executed in the framework PKB “Room for the River” in order to lower the water levels in the river area during normative high discharges. The plan Ontpoldering Noordwaard is one of them and has as aim to inundate parts of the Noordwaard during high discharges. Water coming from the Nieuwe Merwede as result of high...

This report presents an edited collection of memoranda prepared over the past forty years on several aspects of inlet hydraulic and sedimentary characteristics, and is being published because of its general value to the GITI, as well as for its potential use in stimulating other researchers studying tidal inlets.

Considerations on fluid motion in and around closure gaps, two-dimensional local scour in loose sediments, local scour caused by vortex streets, behaviour of dumping material when exposed to currents, results of model tests applied to an actual project *** The closure of the final gaps is the most difficult part of the construction of the dams...

White, W.R. (author), Paris, E. (author), Bettess, R. (author)
Rational regime relationships for the width, depth and slope of a river in equilibrium are developed using the Ackers and White sediment transport formula and the White, Paris and Bettess friction relationships, together with a principle of maximum sediment transporting capacity. This concept of maximising the sediment transporting capacity is...

The principal features of the numerical model developed herein for calculation of flow and sediment-transport distributions in alluvial-river bends may be summarized as follows: i. The secondary-flow strength and the bed topography are uncoupled from the calculation of distributions of lateral shift velocity and streamwise velocity. This is...

In this report analytical solutions are developed for the bed load transport in rivers under unsteady conditions. A parabolic and a hyperbolic model are developed.

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...

Prins, A. (author), de Vries, M. (author)
Often the need is felt to schematize a river regime by one single discharge, the Dominant Discharge, and to use this discharge for prediction of changes in a riverstretch as a consequence of riverworks. This article discusses some methods, as given in literature, to determine the Dominant Discharge and gives a way to compute this discharge by...

The present report gives a summary of all the data collected during the field campaign at the beach and in the nearshore zone near Egmond aan Zee, the Netherlands in 1990. The field experiments are executed with the overall goal to improve the knowledge of the processes which govern the depositional and erosional responses of the surfzone,...
