Cornish, B.A. (author)
With the aid of a grant from the Water Research Foundation of Australia, the Water Research Laboratory has undertaken an investigation into surface treatments for small farm dams Vegetal cover with natural gr asses and low cost soil and bitumen admixtures are under study. As a preliminary to laboratory and field testing, a survey of available...

This is a progress report on the Homer Spit Beach Erosion Study. Information is presented regarding the rapid acceleration of the erosion processes due to the subsidence of the Homer Spit during the 27 March 1964 earthquake. The effect on existing groins both before and after the quake are discussed. Immediately after the quake, emergency...

The study area encompasses 18 miles of Oregon coastline known as Clatsop Beach, which lies between the Columbia River south jetty and Tillamook Head, south of Seaside, Oregon. The physical changes (including man-made changes such as jetty construction which was initiated in 1885) that have occurred in the area since 1792 are described and...

Wave and sand movement conditions must be right for a coastal groin to produce the beneficial effects it was built to achieve. Some groins produce no shoreline improvement; some groins prove harmful; some that act beneficially also cause harm elsewhere, and disputes follow. Design data are sparse, so experience and judgment become important...

Model studies formed a basis for investigating the hydraulics of bywash spillways for farm darns When constructed in natural earth such spillways are trapezoidal in cross section The surface of the spillway needs protection from scour and this protection is usually in the form of grass. These tests extended to variations in spillway geometry and...

The time scale of local scour is of importance in many model studies of practical problems. The use of a time scale is justified by the similarity in experimental scouring holes under different conditions. A time scale is derived from experiments with a wide range of length scales, velocity scales and material scales. The influence of velocity...

As part of a program of research aimed at improving the design and construction of farm dams, the Water Research Laboratory, has with the aid of a grant from the Water Research Foundation of Australia, undertaken a study of the protection afforded to spillways by various low cost surfacing techniques. These include vegetal cover by natural...

This report is the fourth in a series dealing with the use of natural grasses and bituminous and soil admixtures for surfacing farm dam bywash spillways. When the work reported here was completed, the test channels were demolished to make way for new construction, and no further tests of this nature are contemplated. The previous report (Yong...

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...

Carstens, T. (author)
The gravity platforms in the North Sea, sitting directly on granular seabeds, may be undercut by scour and need scour protection. Conventional methods of protections are developed for structures 1or 2 orders of magnitude smaller and seem unnecessarily conservative when scaled to these larger sizes. The reason is that some of the flow details...

Gossé, J.G. (author)
A knowledge of the distribution of sediment in terms of bed and suspended load is essential for a good working description, both qualitative and quantitative, of a coastal sea. A variety of physical, chemical and biological processes in coastal waters are directly connected to, or influenced by, the sediment regime present there. Physical...

The terms 'wash load', 'suspended bed material load' and 'bed load' are not clearly defined but, if applied with care, provide a useful basis for sub-dividing the total discharge of sediment in a river for the purpose of measurement. The accuracy with which each of the three types of sediment transport must be measured will depend on their...

Erosion of banks and dikes subjected to water motion can be prevented, for instance by application of cellular concrete revetment blocks. This type of revetment combined the merits of a closed block revetment and a slope revetment consisting of loose materials. Advantages are high permeability, high stability against wave attack and low block...
