Zuiderzee Works Zuiderzee Works The Zuiderzee Works () is a man-made system of dams and dikes, land reclamation and water drainage work, in total the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large, shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders. Its main purposes are to improve flood protection and create additional land for agriculture. The American Society of Civil Engineers declared these works, together with the Delta Works in the South-West of the Netherlands, as among 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
