The Pearl-Qatar project involved the detailed design of the reclamation works for the 400 hectares new island, requiring approximately 13.5 million m3 of fill, and the associated sea defence structures for the 40 km of new shoreline.
Numerical hydrodynamic model studies were completed to determine the hydrodynamic design basis and to ensure proper water exchange in the various coves of the island as well as in the surrounding waters.
Different beach environments
The development includes private beaches along most of the perimeter, which adds to the aesthetics and exclusiveness of the development.
Different concepts have been developed to create a variety of beach environments that are optimised to suit the local conditions and requirements. Along the shores facing north and east, relative long pocket beaches have been introduced.
The sand is retained between large groyne structures. Private open beaches have been separated by beach breakwaters at one of the shorelines facing southwest.
Terraced beaches Generally, terraced beaches have been used where the wave impact is oblique and an open beach would be eroded.
The terraced beach type consists of a low crested revetment behind which a sand beach is constructed.
Venice-type development
Concrete block-gravity quay walls are applied in the western cove and along the channels in the Venice-type development at the north-west shore to facilitate mooring of boats and to create the confined channel system.
The eastern end of the island features nine individual islands, each with a private beach and boat harbour.
