At present too little use is made of the opportunities that the design and construction of land reclamation offer for the underground storage and recovery of fresh water. The managed aquifer recharge systems in the coastal dunes of the Netherlands are a good example of successful subsurface water storage. And it is to be expected that the sandy deposits of land reclamations could serve a similar purpose. This in turn will contribute to a sustainable development of land reclamations.
An increase in the quantity of dredged material combined with a decrease in available land for disposal has led to extensive research for unusual ways to improve and use the dredged soil.
When expanding populated urban centres, old inner city land or the hinterland is often expensive, uneconomical or unavailable. Building new land in nearby water offers viable opportunities.
