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...

The engineer required to calculate theoretical wave characteristics such as wave profiles and wave forces and moments on piling, is confronted with a problem which includes (1) selecting one of a number of available theories and (2) calculating the required information which, for some of the theories, is a relatively complicated procedure. This...

The classical problem of describing the characteristics of deep water waves of finite amplitude is considered. The method of analysis initially follows that of Nekrasov, but differs in that a non-linear algebraic equation is derived. This equation is solved to the third, fifth and fifteenth order by means of a digital computer and the data is...

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...

A computational formula is developed for determining, from the sea surface spectral density, the spectral density function of the force per unit length at a point on a vertical pile. A surprisingly accurate and simple approximation for the formula is presented and used to explain the near proportionality between the spectral densities of force...

During the past few decades, industrial demands for buried shell have been rapidly increasing. Highway construction, the petrochemical industries, and cement manufacturers are among the major users of shell. Semi-fossil oyster shell is found in tidal embayments in deposits of varying thickness and is dredged from depths varying from two or three...

Momentum flux considerations are used to formulate a differential equation governing the growth, with distance, of the mean longshore current velocity in the surf-zone on a plane, impermeable beach due to monochromatic waves. The equation is solved for the flow situation downstream of a surf-zone barrier and is shown to compare favorably with...

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...

A semi-empirical study l~as made of the attenuation of water waves in a rectangular channel, the side walls of which had been provided with regularly spaced roughness strips. Such strips were found to be highly effective wave dampers. A dimensionless resistance coefficient could be deduced from the attenuation data; this coefficient was mainly a...

A method is presented for the evaluation of an orthogonal coordinate system of particular use in the study of the diffraction of long gravity waves near islands of irregular shape. The problem involves a conformal mapping of the island onto a coordinate plane in which the island contour is a unit circle. The mapping relation is evaluated by an...

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 city and harbor of Hilo, located on the northeast coast of the island of Hawaii, have been severely damaged by numerous tsunamis. Physical features which play an important role in the formation of tsunami bores at Hilo are the submarine ridge formations in deep water outside the bay mouth and the nearly vertical cliffs along the Hamalcua...

The construction of relatively short groins to trap fillets of sand along coastal reaches characterized by prevailing littoral transport has become a well-known practice in coastal engineering. Less common, but often equally important, is the use of long groins to form artificial headlands which trap sand more or less permanently in artificial...

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...

The maintenance of pole, stake, and pile structures in streams and waves has been important to man from antiquity. Because of the common occurrence of the flow of a fluid past a cylinder, and the simplicity of the boundaries, one might expect that long ago all related problems could have been solved . However, if one experiments with forcing a...

It is common engineering practice in a hydraulic model study involving both gravity waves and a solid structure to measure the hydrodynamic forces on the model of the structure and then calculate the resulting internal structural stresses. Because of the large variety of available elastic material, and the latest development in solid state...

An 80- mile reach of the central California coast, extending from the mouth of the Russian River in the north to Half Moon Bay in the south, was studied for the characteristics of sediment movement in the nearshore zone. From the results of a large number of beach and offshore sediment samples and other information, several techniques were...
