The works consist of dams, sluices, locks, dykes, levees, and storm surge barriers located in the provinces of South Holland and Zeeland. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised. Along with the Zuiderzee Works, the Delta Works have been declared one of the Seven Wonders of the
Water resources management in modern Egypt Nile sediments. Furthermore, agricultural land losses will occur as a result of soil salinization. The extent of vulnerability of the Nile delta to increases in sea level varies. One study estimates that 30% of the Delta and Alexandria coast is vulnerable, 55% is "invulnerable" and 15% was artificially protected in 2003. High-risk areas in and near the Delta include parts of Alexandria, Behaira, Damietta and Port Said governorates. According to Omran Frihy, a retired coastal researcher, authorities are spending US$300 million to build concrete sea walls to protect the beaches of Alexandria. Sand is being dumped in some areas to
