When building a large sxale land reclamation, the safest way is to shift the existign profile over the required distance of the reclamation project, up to a depth of say 20 m. This way the profile in cross-shore direction does not change and therefore also cross-shore sediment transports will be the same as before the land reclamation was made. A large disadvantage however is that a very large amount of material is needed for realising hte reclamation. This makes the reclamation very costly.
