[STUDY] Sand quality in Dubai

[STUDY] Sand quality in Dubai
| admin |

Is there a difference in sand quality along our Dubai coastline? 

Guides to the best beaches in Dubai can easily be found online, but there is little on the quality of the sand, even though sand beaches are popular with residents and tourists alike. 

Filip Stefanovic, Technical Engineer at Ecocoast, carried out a study to investigate the quality of the sand along the coast of Dubai, in the United Arab Emirates. Sand quality sampling activities were done on eleven selected beaches, including the beaches of Bluewaters Island, JBR, One&Only Royal Mirage, Club Vista Mare, Madinat Jumeirah, Jumeirah Beach near Burj Al Arab and between the first and second groyne, La Mer, Secret, Kite and Sunset beaches.

Altogether, 44 samples were collected from backshore and foreshore, and tested by a specialised laboratory, in order to determine particle size distribution and particle density of sand, which constitute an important aid to understand coastal processes, and more importantly, how best to replenish sand on a beach that is eroding.

Among the key findings of the study are:

  • Majority (over 60%) of the tested beaches have a particle density higher than 2.65 g/cm3, both at backshore and foreshore areas. 
  • Mean grain size (D50) of backshore samples of all beaches range from 0.212 mm to 0.475 mm. Sand at the backshore is generally finer than sand at the foreshore.
  • The coefficient of uniformity of sand particles varies. Both backshore and foreshore samples show a Cu coefficient lower than 2.0, or between 2.0 and 3.0. 
  • Beach sand has a palette of different colours. Dubai beaches are mainly composed of off-white, light grey, yellow golden and reddish sand.
