A one-meter wide, meandering flume with movable sand bed was utilized in these experiments. Uniform flow was established at discharges of 20, 35, and 50 l/sec. Velocities near the bed, the distribution of sediment in transport, bed geometry, and strength of secondary flow were determined at each discharge . Bed shear stress was assumed to be...

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...

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...

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 ...

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...

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...

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...

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...
