The works consist of dams, sluices, locks, levees, and storm surge barriers. The works were initiated after the North
Delta Works Law (Dutch: "Deltawet"). This required the government to keep risks of catastrophic flooding within these limits and to upgrade defences should new insights into risks require this. The limits have also been incorporated into the new Water Law ("Waterwet"), effective from 22 December 2009. The Delta Project (of which the Delta Works are a part) has been designed with these guidelines in mind. All other primary defences have been upgraded to meet the norm. New data elevating the risk assessment on expected sea level rise due to global warming has identified ten 'weak points.' These have been upgraded to meet
