White, W.R. (author), Mill, H. (author), Crabbe, A.D. (author)
In 1972 Ackers and White (Refs 24 and 25) proposed a new sediment transport theory and tested the theory against f1ume data. This data consisted of about 1000 measurements with particle sizes in the range 0.04 < D(mm) < 5 and sediment specific gravities in the range 1.07 < s < 2.65. Subsequent phases in this investigation have included (i) the...

Kamphuis, J.W. (author)
The selection of scales for models with short waves, long waves and unindirectional current is discussed with particular emphasis on boundary layer motion and movement of sediment. The paper attempts to outline the present state of the art and to provide a framework for future research in the area of coastal sediment transport models at Queen's...

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 aims of this paper are: 1. To publish some available coastal measurements and computations of more than local importance. 2. To investigate the influence of groynes in practice. 3. To investigate the motion of the gullies in the outer deltas. The following conclusions are drawn: 1. The gross littoral drift along the Dutch coast is of the...

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...

This report shows the results of a detailed analysis of the various littoral processes which affect the California Coast between Pismo Beach and Santa Barbara. The method involves the concept of a sand budget based on the transport rates of all significant littoral processes. Each process is examined to assess the sedimentary contributions ...

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...

Belly, P.Y. (author)
Sand movement on the coast by wind action can be a major factor in some areas, yet very little is known about the basic mechanisms of movement by wind. With the growing use of artificial placement of sand material for beach restoration and protection, movement of sand by wind in the area shoreward of the waterline has become more and more a...

Meyer-Peter, E. (author), Müller, R. (author)
In the following paper, a brief summary is first of all given of the results and interpretation of tests already made known in former publications of the Laboratory for Hydraulic Research and Soil Mechanics at the Federal Institute of Technology, Zurich. After that, an attempt is made to derive an empirical law of bed-load transport based on...
