Palm Islands [SEP] Construction effects and repercussions
The construction of the Palm islands along the coast of Dubai has caused several large environmental changes: a reduction in the area's aquatic life, erosion of the coastal soil, and irregular sediment transport along the shore. There is also a dramatic change in wave patterns along the coast of Dubai due to the rock walls constructed around the palm islands: instead of hitting the shores directly, the waves move in an unusual manner around the new obstruction. This has led to the weakening of the shores of Dubai. The origin of most of the environmental damage stems from disturbed sediment from construction of the Palm islands.
