Order Of Magnitude

Methods for estimating wave overtopping of coastal structures are reviewed and compared with the very limited available data and with each other. The different methods yield results which can vary more than an order-of-magnitude. For vertical seawalls, the U. S. Army Engineer Shore Protection Manual method estimates more overtopping than Goda's method except in very shallow water. For sloped structures, the Shore Protection Manual method usually estimates less overtopping than Battjes' method and Owen's method. However, data for adequately evaluating how well these methods predict overtopping has not been published.

The 'Afsluitdijk' is a 32 km enclosure dam which separates the Wadden sea and the Lake IJssel. The dam currently undergoes a major rehabilitation to meet the requirements with regard to water safety. The Dutch Ministry of infrastructure and Water Management (Rijkswaterstaat division) has commissioned Levvel, a consortium of BAM, Van Oord and Rebel, to prepare the design and carry out the reconstruction of the dam including sluices and highway. The project includes reinforcement of the armour layers and wave overtopping reduction. As part of the contract Rijkswaterstaat prescribed the contractor (Levvel) to verify the design with large scale physical model tests (min. 1:3 scale). These tests were carried out in the Delta Flume of Deltares. Prior to the large scale tests, smaller scale tests (1:20) have been carried out to optimize the design with regard to armour stability and wave overtopping. The research described here focuses on the wave overtopping.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/kPga0wVCCIE

Protection Structures

Analysis of a large shoreline database (from 1878 to 2017) and recompilation of information on type/age of shore protection structures along the Northern Tuscany, allowed a deep insight of the progressive armouring of this coastal sector. The area experienced beach erosion since the end of the 19th century due to reduced sediment inputs from rivers and harbour constructions. Shore protection structures started to develop at the beginning of the 20th century, first to protect settlements and coastal roads, later to maintain a beach for tourist activity. The changing of the goal and the increasing awareness of the negative impact of some structures resulted in an evolution of coastal defence projects: initially, seawalls and revetments, later detached breakwaters and, more recently, groins. Today, a reduction in hard structures is perceived by removing or lowering detached breakwaters and groins below mean sea level. The forcing function of the growing tourism industry is producing a demand for projects and their design is detailed in this paper: results will be of use in the correct design of a long-term, general, erosion management plan to restore the natural sediment circulation patterns.

The purpose of this paper is to present the results of three years of field observations on low cost beach protection structures in use on the Great Lakes. The structures were studied in regard to their effectiveness as beach building and protective devices and with respect to their durability in resisting ice and wave forces. The term "low cost" refers to structures which cost between $10 and $50 per foot of frontage at 1952 prices.

Abstract. The shores of seas, lakes, bays and reservoirs under the action of wind waves, drifting level ice, rainwater, wind erosion and other factors are subject to intensive destruction. As a result of this, the areas of valuable agricultural land and other lands are reduced. The destruction of the coasts is accompanied by landslides, which reduce the area of settlements where residential buildings, urban buildings, industrial enterprises, park areas, roads and other communications are located. In such cases there is a need for the construction of special protection structures, which will protect coasts from destruction. There are two methods of coastal protection ‒ active and passive. Experience in coastal protection shows, that in many cases, these methods can be successful when applied jointly. The types of structures of shore protection structures are diverse. Therefore, the main task of designers is to choose the most optimal of them, taking into account the climatic, hydrological and engineering-geological conditions of the region construction. The aim of this work is to create a progressive method of construction of shore protection structures on shallow shores of the seas and in shallow reservoirs. This paper considers the existing and innovative designs of shore protection structures made of various materials, the conditions of their use and technical and economic characteristics are analyzed. Based on the analysis, a progressive method of construction of shore protection structures from gabions is proposed. The using of the proposed method for the construction of shore protection structures from a box type gabion will speed up the construction process of such structures, as well as reduce the volume of material at the base, which will lead to a significant reduction in the cost of construction. The mass of gabions in each project should be determined on the parameters of the waves of the design storm in accordance to the recommendations of standards.

Between the breakwaters of the harbour entrance of Rostock-Warnemünde, located at the Baltic Coast of Germany, a small marina is situated. In 1999 these breakwaters were modified in order to meet the nautical requirements of larger ships. From this time on, serious problems for the pleasure boats were observed due to wave disturbance. New structural measures like floating breakwaters and vertical walls (small length) showed only poor improvements. The objective of the investigations was the functional design of wave protection structures and a layout able to meet the user requirements on a modern marina with focus on competitive sailing sports. The investigations were assigned by the Sport Confederation of the Federal State of Mecklenburg-Vorpommern, Germany. To accomplish this objective, numerical simulations as well as small scale hydraulic tests were performed at the University of Rostock.
