Dredging in the Maldives – How Satellites Can Help
DREDGING IN THE MALDIVES Copernicus Sentinel 2 data is being used in the Maldives to improve the efficiency of dredging for sand so saving ship time on site and reducing negative environmental impacts derived from damage to endangered coral reefs. THE CHALLENGE The Maldives comprise 26 atolls and over 1000 islands sitting on either coral structures or sandbars. It is the lowest lying country in the world with its highest point at 2.4m. Offshore, there are many further reefs sitting just under the surface. The atolls are separated by navigable channels which are subject to change as are the islands themselves as changing currents erode or deposit sand. The low-lying islands are very vulnerable to damage from rising sea-levels and increases in the frequency of violent storms. Coastal protection and reclamation of land lost to the sea is a permanent process. There is an almost constant need for either the dredging of channels or the depositing of sand to protect island areas. To avoid transport costs, wherever possible, engineering works for construction of barriers are made using sand obtained by dredging the sea-floor. Hence, up to date maps of the sea-floor are valued to help know where the sand can be found and extracted with good operational efficiency (ie the extent of the sand area) whilst causing minimal environmental damage (destructing coral reefs or disturbing important sea vegetation). The maps also help to navigate the ships with the knowledge of where they can move safely. However, in many parts of the world, including the Maldives, the available hydrological maps are out of date or simply not accurate enough to give reliable guidance for modern dredgers. -
