Risk mitigation[edit]
To counteract with the waves and the constant motion of the sea, wave blockers were built all around the palm island. They were 3 meters high and 160 kilometers in total length. Expanded over a length of about 11.5 kilometers, the base of these stoppers and the island as such were constantly monitored during construction process with the help of deep sea divers. They check for the proper alignment and placement of the rocks beneath the surface to ensure its stability. Shape of the island as it got developed in the middle of the sea was constantly monitored using the global positioning system (the satellite was placed about 676 kilometres from sea level into space). The sand on top of the island was sprayed by a technique called rainbowing.[13] Here the sand from the dredging ships was sprayed on to the land. The whole island was set such that there was no stagnant water between the island and the water breakers. So in order to achieve this, there were small structural modifications done on the breakers that outlined the island. Hence making the sea water to move through in and out of the breakers without causing any damage to the island.[14] To prevent erosion of the soil from the island, there were constant maintenance setups to spray soil along the coast of the island and also along the Dubai coast. Coastal ecology was recovered with the help of nature itself. These changes began attracting newer species of fishes and also reef formations. Every 6 weeks sea divers go down under water to check the marine life as part of their monitoring process. Precautions were also taken to prevent the process of liquifaction of the sand on the island (below the upper surface). This process of liquifaction was caused due to movement of the rocks and sand and also under water erosions before and after construction. Vibro-compaction technique was the method that was employed to prevent the process of liquifaction.[15] This was carried out in order to hold the composition of the island's base together and also to make a strong foundation for further constructions.[16]
