Hydrography of the Dutch Wadden Sea

Postma, H. (author)

In this paper an attempt has been made to describe for the Dutch Wadden Sea water movement, transport of suspended matter and the cycle of suspended organic matter. Stress has been laid on the fact that these are related subjects, which therefore ought to be studied in combination. The discussion was based on observations made in the years 1949...

Tidal computations in shallow water - Report on hydrostatic levelling across the Westerschelde

Dronkers, J.J. (author), Schönfeld, J.C. (author), Waalewijn, A. (author)

A survey is given of the established practice of tidal computations in the Netherlands. The dynamical analysis of tidal elevations and currents in shallow waters is of great practical interest when coastal engineering projects are undertaken, like the Zuiderzee or the Delta project, both in the Netherlands. Tidal computations have to be based...

Investigation of excess water-pressure under the asphalt facing of sand-cored dykes: Paper for 9the Conference of the International Association of Hydro-Environment Engineering and Research, Belgrade, 1961

Bischoff van Heemskerck, W.C. (author)

The excess pressures anticipated underneath the asphalt facing of a number of sea dykes were determined with the aid of plate-shaped electrical conductors and alternating current. As these excess pressures are influenced by factors varying from place to place in the prototype, a series of tests were carried out in which one or more of these...

Jet diffusion in stagnant ambient fluid

Abraham, G. (author)

Submarine outfall disposal of domestic and industrial sewage is a method of disposal of steadily growing importance. The flow from an ocean outfall is essentially that of a submerged horizontal or vertical jet. Thus a study of the hydrodynamics of such jets is needed to evaluate the dilution of the sewage flow. A study of this kind is presented...

On the time varying horizontal water velocity of single, multiple, and random gravity wave trains

Wells, D.R. (author)

In this dissertation some characteristics of the horizontal water velocity for single, multiple, and random gravity wave trains are studied. This work consists of two parts, an analogue study and hydraulic measurements. An important aspect in this work is to suggest the horizontal water velocity asymmetry as a criterion for sand movement by...

Water waves generated by underwater explosions

Jordaan, J.M. (author)

Explosion waves were simulated by plunging a parabolic surface of revolution in and out of an indoor t est basin 3 feet deep by 92 feet square. These impulsively-generated Water waves are found to be dispersive as evident from the following properties : The period and the celerity of the individual waves increase with travel time, and the...

The influence of wind on open channel flow

Plate, E.J. (author), Goodwin, C.R. (author)

The effect of wind shear stress on the flow in an open channel is investigated for the case where wind and water move in the same direction. The investigation is based on experimental data obtained with a unique wind water tunnel. A method is developed by which it is possible to separate water surface shear stress and bottom shear stress. . The...

Ocean temperature measurements for power plant design

Cheney, W.O. (author), Richards, G.V. (author)

For many years the Pacific Gas and Electric Company has been measuring water temperatures in the ocean and other bodies of water in connection with the design of thermal power plants. This subject is timely because of the widespread interest being shown in the field. Since the beginning of this temperature measurement work, various methods and...

The influence of Reynolds number on wave forces

Rance, P.J. (author)

Information, published to date, or. the effect of viscosity on wave forces is very indefinite. A series of experiments carried out in the Pulsating Water Tunnel at the Hydraulics Research Station Wallingford under closely, controlled conditions clearly defined the variation of primary forces with Reynolds Numbers up to 6 x 10 5 . Additionally...

Laboratory investigation of impact forces

Führböter, A. (author)

A special impact generator was constructed in order to produce water impacts with velocities which are not available in scale models with waves. The water impact was generated by a jet suddenly striking upon a measuring area. Even under same conditions of impact, stochastic scattering of the peak pressures was observed; but for all test series...

Statistical evaluation of wave conditions in a deltaic area

Svasek, J.N. (author), Battjes, J.A. (author)

Coastal engineering problems concerning wind waves and swell can be solved with the aid of hydraulic or mathematical models. The irregular wave field i.e. the state of the sea surface can be described in a sufficient way for engineering problems either by parameters such as significant wave height and mean wave period, or in the form of power...

Introduction to special section on Uncertainty Assessment in Surface and Subsurface Hydrology: An overview of issues and challenges

Montanari, A. (author), Shoemaker, C.A. (author), Van de Giesen, N.C. (author)

This paper introduces the Water Resources Research special section on Uncertainty Assessment in Surface and Subsurface Hydrology. Over the past years, hydrological literature has seen a large increase in the number of papers dealing with uncertainty. In this article, we present an overview of the different sources of uncertainty and the...
