Climate change and beach erosion disaster "a study on beach protection in the gaza strip"

Abstract

The erosion threatens the coastal life, which affects people's economic, tourist and recreational life as well as the daily life. Marine life is an indispensable foundation in a coastal country such as Gaza. The main reason of the erosion is the sea waves; it's working on empty the beach sand, thereby flooding and scouring the area as it ebbs and removing part of the unconsolidated sand. The available data indicates that 350,000 cubic meters of sediment transport capacity on the Gaza beaches every year. This paper discusses coastal protection techniques from erosion included in this, slope protection, beach nourishment and offshore breakwater, and analyze their impacts on coastal protection to provides the best possible solutions in environmental, economic and engineering terms. The study focuses on environmentally friendly technologies such as Geotube & GeoWeb 3D, which helps in maintaining the beach and the environment at lower costs. Finally, the results showed that the use of Geotube submerged in two rows will work very efficiently in breaking waves to reduce beach erosion, as well, the use of GeoWeb will protect the slopes efficiently and maintain its stability Also. Through the results of the research, it was found that the use of GeoWeb reduces the impact of climate change and helps in developing the environment and improving the quality of the tourism aspects. Also results shows the role of these options in minimizing the impact of the global plastics crisis where recycled plastics can be used as raw materials in the manufacture of the GeoWeb and GeoTubes.
