Optimum Solution

An artificial beach nourishment used to replenish an eroding part of a coast may seem expensive and the need for repetition may discourage coastal managers. However, careful considerations of capital and maintenance cost frequently prove that it may be, in fact, the optimum solution. An added advantage is that the recreational function of the beach is preserved. In spite of a great number of research-reports and publications on coastal processes and beach nourishment, the practical applicability of this knowledge is still in an initial stage, i.e. formulating the general concepts and trying to test their validity and practical applicability. On the other hand, the solution of many practical coastal engineering problems cannot wait until complete understanding of these processes and the existing knowledge on this subject (though limited) should be made available for designers and managers involved in coastal engineering. This was the main reason for the Rijkswaterstaat (Dutch Public Works Department) to prepare a manual on artificial beach nourishment. In 1983, this Department established the task-group 'Profile Formation of Beaches', with the aim to study the relevant aspects of beach nourishment. These aspects concern among other things the influence of a beach fill on the coastal morphology and the environment, and the design and execution of a beach nourishment scheme. The members of the task-group originate from various governmental departments, research institutes (Delft Hydraulics) and private organisations (Volker Stevin Dredging, Zanen Verstoep Dredging Contractors). In addition to the members of the working-group some other persons and organizations (also outside the Netherlands) have contributed to the final report. The results of the studies have been described in a Manual on Beach Nourishment (Manual, 1986). This manual contains both theoretical and practical information, and is intended for persons and organisations who are involved in the prevention of beach erosion. Nearly all available and relevant literature to this subject has been incorporated. The actual paper reviews part of the contents of the Manual and summarizes aspects related to the aim, the different types and the design process of beach nourishment schemes.

Gas Supply

The Bacton Sandscaping scheme is a large-scale beach nourishment, designed to protect the Bacton Gas Terminal from cliff and beach erosion while also reducing flood and erosion risk to the communities of Bacton and Walcott, buying the time they need for adaptation to coastal change. The scheme was inspired by the even larger Dutch Zandmotor project, translating the concept to the different geography and governance setting of the UK - it can be seen as the Zandmotor's 'little nephew'. The term 'Sandscaping' was introduced to illustrate the large-scale and ambitious nature of the concept: work at a large scale, designing to work with natural processes and to achieve multiple objectives.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/FA3DjdCgKrk

Sand Supply

A natural beach system is in equilibrium when there is a balance between sand supply and erosion such that the volumes of material entering and leaving the system are just equal. If the erosion rate exceeds the supply rate, a beach retrogrades; if the erosion rate is less than the supply rate, a beach progrades. Unfortunately, coastal engineering works, which are meant to improve the shore for commerce or recreation, often upset this delicate balance with very deleterious results: great accretions of sand and high dredging costs, accelerated beach erosion and much property damage. It is the task of the geologist to determine the secular equilibrium conditions of a beach system and to supply the coastal engineer with the information he needs to control the natural forces acting on the shore in such a way that this equilibrium is maintained. In order to accomplish this task, the geologist needs to make a thorough study of the source, transportation, and deposition of beach sediment. He must determine the stable position of the shore line and the profile of equilibrium of the beaches through detailed physiographic investigations. The geological report can and should close with the prediction of just what will happen to a natural beach system if man introduces a disturbing element.

Sheltering Effect

Golden Beach in Taiwan is a sandy beach attracting many beachgoers because of its wide sandy beach and beautiful sunset. In recent years, this beach has been eroded. The cause of the beach erosion is considered to be due to the wave-sheltering effect of the Anping Harbor breakwaters constructed 4 km north of the beach. Now the restoration of sandy beach is underway by the construction of groins as well as beach nourishment using sand procured from the downcoast deposition area. This study aims to investigate the cause of the beach erosion of this beach to work out the effective measures against beach erosion.

In the southern part of Sanur Beach in Bali, beach erosion has occurred between groins after extensive beach nourishment, resulting in shoreline rotation between the groins. The cause of shoreline changes was investigated by field observations, including a bathymetric survey and the sampling of seabed materials, and numerical simulations of beach changes were carried out using Noshi et al.’s model. It was concluded that the shoreline rotation was triggered by the dredging of the reef flat, which caused a change in the wave direction on the reef flat due to the diffraction of waves.

Large Scale Project

Beach erosion is prevalent on China’s 18,000 km-long coastline, which has been aggravating due to urban development, river-damming and soil and water conservation projects since late 1970s. Beach erosion threatens the health of beaches of bathing places throughout the world. An effective way to defense the beach erosion is beach nourishment. In this paper, the study on an experimental beach nourishment project, which was conducted to provide data and experience for a large-scale project, was detailed. Field survey was conducted to study the performance of the project. Before and after the project, 8 monitoring profiles had been kept measuring along with the berm positions. The beach profile measurement indicates that after a little retreat the beach got relatively equilibrium, while the berm measurement shown a broadened intertidal zone getting stable eventually. In a word, the filled beach was eroded a little but finally got relatively stable in the survey period.

The Many

In the consideration of problems of coastal engineering in general, and of shore and beach erosion in particular, one is quite naturally apt to immediately focus attention upon our ocean shores to the exclusion of inland areas. Many are perhaps not appreciative of the fact that the five inland fresh-water lakes comprising the Great Lakes system are bordered by eight states having a combined length of shore line of approximately 3,000 miles. (See Fig. 1) Only in recent years has there been a general awakening of interest in the many and varied problems of erosion which occur along these inland coasts. The purpose of this paper is to summarize the problems existing on the Illinois shore and to outline the steps which have been taken at the State level in seeking a solution to those problems.
