Construction of the arms of the marina at The Wave, Muscat in Oman has been completed on schedule and is safer than mandated, according to the developer.
“Seafront developments face challenges that need to be dealt with,” said The Wave, Muscat CEO Nick Smith.
“Threats from rising sea levels, global warming and climate change are concerns on everyone’s mind when purchasing a water-front home. At The Wave, Muscat we have applied stringent rules and have incorporated long term plans in the preparation and design stages to mitigate the impact of these issues.”
The primary protection to the marina and development will be provided by the Offshore Reef Breakwater. This structure is 2km long, located 1km seaward of the marina and will comprise over 1 million m3 of rock materials and about 18,000 individual concrete armour units called Core-Loc.
The Core-Loc units weigh 12 tonnes each and heavier 16.5 tonne units are used at the ends of the breakwater which are subjected to more severe conditions during a storm. The finished height of the breakwater will be +7.5m above Chart Datum.
“We have implemented detailed risk management plans, which have gone beyond the traditional EIA studies and recommendations, which keep us abreast of possible impacts of environmental change,” said Smith.
“The construction at the marina is an example of The Wave, Muscat going above and beyond the standard design practices in order to give our residents complete peace of mind and ensure the longevity of the project.”
During storms, sea swell will be transmitted through the rock structure of the breakwater together with waves generated by over-topping of the breakwater and diffraction (the motion of the waves bending around obstacles) round the ends of the breakwater.
The marina and development will be protected from these swells and waves by the East and West Revetments. These structures are 0.7km and 1km long respectively and will be +5.9m above Chart Datum comprising rock armour of up to 8 tonnes size.
The marine structures have been designed considering wave and wind events up to a one in 250-year return period which could result in a significant wave height of 5.95m for the breakwater.
Seismic events and the future rise in sea level has also been accounted for in the design. Significant wave height is defined as the highest of one in every three waves.
The Wave, Muscat comprises residential, commercial, hospitality and leisure units set around a 6kms long natural beach, a Marina and a boulevard.
