  3. Erosion at Dubai • According to data collected, it is said that every two years, 50 meters of the coast is being eaten by the ocean. I am specifically talking about Umm Suqeim 1. • They are investing on protecting homes, places like: • Umm Suqeim 1 • Jumeirah Beach • JumeirahHarbour • Mina SiyahiHarbour and more

  4. THE PROBLEM!! • In Umm Suqeim 1, there are hotels, restaurants and most importantly, houses at the beach front. This places could be damaged and gone if no one takes action against beach erosion. • That is why Jumeirah Coastal Zone Management Plan (It also describes measures to protect other places like JumeirahBeach or Mina SiyahiHarbour) comes and meets the requirements like fast population growth, increasing tourism and the extending urban development along the coast.

  5. Main topic Umm Suqeim 1 Erosion

  6. How it is effected

  7. Solutions • Groynes • Extensions to the groynes • Offshore breakwaters • Offshore islands • Extensions of an up drift spur • Extensions to the breakwaters

  8. Description For Solutions • Groynes are built basically to prevent longshore drift. A groyne is like a barrier to stop the sedimentbeing carried away by water. It holds the sand together. • Breakwaters are similar to near shore islands or groynes which are designed to reduce the wave energy. There are different types of breakwaters, headland, detached or a single break water. Breakwater Groyne

  9. The best solution • I think the groynes(sandbags relating to Umm Suqeim1 problem) is a good solution because it is quick and simple. Well, maybe it is not that simple but it is definitely less expensive then making offshore islands or an extension on a spur. • It is also quick and could be easily redone or extended if the sandbags gets damaged, I am not saying it is not expensive and that it takes 3 minutes to make the required amount of sandbags. No, you could be sure it costs quite a lot to bring the sand over (even though we are in the desert) and they are not only putting 5 sandbags on the beach are they? I am sure there is a huge amount of sandbags required to protect the coast in Dubai being eroded.

  10. Filling sandbags with two to five tons of sand

  11. They dig a shallow base before placing the sandbags on the shore, forming a soft groyne

  12. The sandbags are positioned 100 meters away from the shore, forming protective groynes.
