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.

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

Abstract Maintaining and retaining a quality sandy beach is a primary requirement for attracting people and tourists in any coastal country. Tourism Enterprises Company (TEC) in Kuwait owns 230 m long sandy beach in Ras Al-Ardh Sea Club, Salmiya, Kuwait. The beach has been eroding because of strong hydrodynamics forces from waves and currents. TEC wants to develop a stable sandy beach of 30 m wide. Kuwait Institute for Scientific Research (KISR), Kuwait is assigned to carry out the required scientific studies. In order to make sure a stable quality beach will exist, KISR has carried out the needed studies, which involves the field measurements such as bbathymetry survey, current and tidal variations, physical characteristics of beach soil, beach and sea bed profile, establishing the design parameters such as waves, currents, tide and wind. Hydrodynamic model study using DELFT3D model for the present and for the proposed extended groin conditions with beach nourishment were carried out. Also numerical modeling using GENESIS model to understand the future shore line changes due to the proposed development was carried out. Design of Groins to estimate the weight of armor units and weight of inner layers were carried out. The particle size and quantity of sand needed for reclamation of 30 m wide beach was estimated. Based on the study, it is recommended that the sandy soil to be used for 30 m wide beach nourishment should have D50 greater than 0.42 mm (say 0.5 mm) and D10 greater than 0.25 mm. The borrow pit much be selected by keeping this soil characters in mind. It is recommended to use a submerged offshore breakwater in order to retain the beach sand in place and for reducing the maintenance nourishment. Otherwise, large quantity of the capital nourished beach sand will escape into the deeper water due to strong current coupled with waves and steep seabed slopes. Environmental Impact Study was carried out as per Kuwait Environment Public Authority requirements to bring out the impacts due to beach filling and the construction submerged offshore barrier and extension of east groin for a distance of 30 m. TEC will implement the recommendations for developing the beach in Ras Al-Ardh sea club and will be useful to attract more people to use this beach.

In recent decades, beach erosions have become severe at sandy beach in the world. The coarser sand nourishment has been noticed in Japan because of the stabilization of the beach coast. However the performance is not clear. Therefore in this study, laboratory experiments were conducted for the beach nourishment using the coarser sand. Through of this experiment, the effect of the coarser sand nourishment was investigated.

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.
