Abstract
Global sea level has been rising over the past century, and its rate has increased in recent decades due to the human activities which lead to global warming. This increase in sea level will cause an advance in seawater (the retreating of shoreline), and it will interfere with the performance of coastal cities. One of the strategies for controlling shoreline changes, sea forward in coastal cities and coastal areas is the usage of geotextile tubes, which is not only an acceptable usage of materials but also an economical solution. In this research, we have attempted to predict the horizontal changes in the southern part of the Caspian Sea shoreline using the theory of eroded and deposited sediment volume balance under the effects of sea level rising. According to predictions, the shoreline retreat will not be perceptible for short periods (1–5 years); but it is significant for long periods of time (10, 20 and 50 years). Then, based on the previous section results, an optimum geotextile tube is designed according to the existing conditions of the Caspian Sea by developing a computer program. The geotextile tube stability has been studied due to the slope of the beach and toe scouring. Also, a geotextile sheet as an apron is designed with a specified domain which is placed under the geotextile tube to prevent toe scouring and stop the movement of geotextile tube.
