The most urbanized part of the Netherlands is situated below sea level and is protected by dikes. By act of parliament allowable inundation frequencies for each part of the country are fixed. In case of two dangers (river run-off and storm surge) it is a problem to determine design values for dikes. Guidelines are developed to solve these...

A reef breakwater is a low-crested rubble-mound breakwater without the traditional multilayer cross section. This type of breakwater, in essence, is a homogeneous pile of stone with individual stone weights similar to those used in the armour and first underlayer of conventional breakwaters. Because of their high porosity, reef breakwaters are...

The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at rhe Hydraulics Laboratory, Department of civil Engineering, university of Aalborg. The object was to study the stability/erosion of the breakwater head and the trunk, the latter exposed to both head-on and oblique irregular waves. To avoid too...

In the last fifteen years the techniques of wave generation 'have advanced to a great extent that it is row possible to exercise controls, on parameters such as wave grouping, wave asymmetries. etc .. , during the simulation process.. This paper describes some of these techniques that were developed at the National Research Council of Canada,...

A description is given of a model developed for the prediction of the dissipation of energy in random waves breaking on a beach. The dissipation rate per breaking wave is estimated from that in a bore of corresponding height, while the probability of occurrence of breaking waves is estimated on the basis of a wave height distribution with an...

The successful design of a marina with respect to seiche conditions presupposes two categories of knowledge. Of these the more difficult to obtain is an adequate description of the local long period wave environment. Somewhat easier, but equally important, is a detailed knowledge of the responses various basin configurations present as a result...

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...

A berm and dune project for shore and hurricane protection was recently completed at Wrightsville Beach, North Carolina. A navigation project provides for a channel 14 feet deep and 400 feet wide through Hasonboro Inlet which forms the southern boundary of Wrightsville Beach. It has been found infeasible to maintain the channel by dredging alone...

Basic principles bearing on the nature of beaches and processes that act to modify them are considered in the light of present coastal development demands. A working hypothesis is developed that applies the principle of the conservation of mass to the mechanics of granular- fluid media. This hypothesis appears to have general application to sand...

Over the past two or three years, Texas A &: M University has been operating facilities offshore of Panama City, Florida, to observe and collect environmental oceanographic data in the Gulf of Mexico. Waves are measured using Hytech resistance type wave staffs. The data is recorded more or less continuously in digital form on magnetic tape. The...

A brief review of groin types and their respective functional designs is presented. Illustrative examples of conventional groins and some of the variations in the basic groin types, which have been constructed in the United States, are shown for comparative purposes.

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...

The equation of continuity and the equation of motion for two-dimensional shallow-water waves are transformed into a set of difference equations which can be solved numerically to obtain the fundamental period and the periods of the higher modes of oscillation of a closed basin of arbitrary shape. From these periods and the difference equations...

Wind action on pre-existing ,waves is examined experimentally in a wind-wave channel, in which the pre-existing waves are generated mechanically by a paddle at the windward end of the channel. Air is blown over these waves, in the direction of ,·rave travel, at velocities up to about 30 feet per second, with the formation of wind-generated waves...

This paper presents a brief discussion of structural damage by tsunamis based primarily on damage produced by recent tsunamis along the northern California coast. Of these recent tsunamis, by far the most damaging was the one of March 1964; which caused approximately $11,000,000 damage at Crescent City, about $300,000 damage at other coastal...
