Ter oplossing van het, aan de "Staatscommissie inzake hooge waterstanden als gevolg van de afsluiting der Zuiderzee" voorgelegde probleem, heeft de voorzitter dezer commissie, de groote natuurkundige H. A. Lorentz, als eerste een betrouwbare en practisch uitvoerbare methode gegeven tot het berekenen. van getijverschijnselen in zeeannen. Deze...

Groen, P. (author)
The behaviour of internal waves in vertically inhomogeneous fluids has been studied theoretically by various authors, from the point of view of general hydrodynamics as well as of meteorology and of physical oceanography (see the list of references, which, however, is not meant to be complete). For mathematical reasons most of them assumed...

Tests have been done in a laboratory flume, to evaluate the influence of vertical rods of 3 mm dia on the hydraulic and sedimentological characteristics of the flow. The first two tests have been done with some 10 cm waterdepth. In both tests the s ame flow rate and sediment transport was used, the only difference between the tests being the...

The paper describes a series of tests made in the Columbia River Estuary model at the U. S. Army Engineer Waterways Experiment Station concerning enlargement of the navigation channel at Mi ller Sands Bar. Tests were conducted to determine the effects of enlarging the channel and to determine the effectiveness of various combinations of proposed...

de Jong, J. (author)
On March 24, 1969, the new wind-wave flumes at the Delft Hydraulics Laboratory (Figures 5 and 6) were officially opened by the Director-General of the Rijkswaterstaat. The design work started in 1964, and the building and installations 1tlere completed in November 1968. A general description of this equipment and some insight into its underlying...

Ferguson, H.A. (author)
The hydraulic model is playing an increasing part in the process of hydraulic designing and it seems even to have taken over the dominant position that experience and tradition had held for such a long time. But, however important the model tests have become, they are not the only means available to the designer, nor does he have to rely solely...

Wind-wave flumes have been added to the laboratory facilities since a long time, in order to simulate natural wind lv-aves. Most wind-wave flui'nes have been equipped in addition with mechanical (regular) wave generators to avoid extreme small model scales. For some time past a programmed (irregular) wave generator has been installed in one of...

Jensen, J.A. (author)
It is described why, and to what extent the practicing engineer makes use of model tests in his design of rubble mound breakwaters. Furthermore an example is shown from practice illustrating the application of models for investigation of wave penetration into harbours. Especially the way in which model tests can confirm and supplement...
